Your Electrical SwitchBoard your backup defence for Electrical Safety

Fuses, Circuit Breakers and Safety Switches

These devices are found in your Switch board understanding these devices and how to use and maintain them will help your management and understanding of Electrical Safety in the Workplace.

Primary Overload response devices (Fuses & Circuit Breakers)

Fuses and circuit breakers are built to fail in conditions of excess current which can overload the electrical wires in your home. These overloads are often caused by faulty appliances. When an overload occurs, the fuse melts before the wires can overheat, which reduces the risk of fire. Circuit breakers will often trip quicker and more importantly they can be reset to help diagnose and remove faults.

  • Always replace a blown fuse with the correct fuse wire.
  • Never use fuse wire that is heavier than the recommended gauge.
  • Never use any other type metal or wire.
  • If fuses keeps blowing, or a circuit breaker trips, check your appliances are not faulty.
  • If fuses continue to blow, or circuit breakers continue to trip after appliances are unplugged, there could be a problem with your wiring. Contact a licensed electrician immediately.

Safety Switches

Safety switches look similar to circuit breakers, but they provide extra protection from electric shock. Safety switches monitor the flow of electricity and if any irregularity is detected, the electricity supply is immediately cut off.
Homes with children or backyard workshops should consider installing safety switches to reduce the risk of electrical accidents. New homes are required to have safety switches installed. Licensed electrical contractors can install safety switches in older homes at a reasonable cost. You can also purchase portable safety switches for appliances and extension cords. Useful particularly when using power tools outside ie Electric Lawnmowers, Hedge trimmers, Drills, circular Saws etc

How to protect your valuable company data on your computers during power interruptions?… Have you considered buying a UPS

Uninterruptable Power Supplies (UPS) Buying Tips
Summers here! … and Summer In Australia means Power Shortages and often leading to Blackouts (no power) or brownouts (low power ie low voltage and current) sometimes these are planned by the Electricity Suppliers to share the extra load during Hot Days… sometimes they occur unplanned because of overloaded or failed equipment either way Your expensive computer or in the case of a business your Server and the data in it could be rendered useless. UPS is the easiest way to protect your hardware and data. For a better and more thorough protection, you need a UPS. It isn’t intended to power you through a blackout though. For that, you would need a generator. Rather, a UPS will let you save your work and power down safely.
A UPS is designed to protect your computer you against such power fluctuations and more importantly, power up your computer even when there is no electricity. Here are a few tips that should help you make a more informed UPS purchasing decision.
Power Outlets
When purchasing a UPS, make sure the power rating is right for your equipment. If you buy one that is rated too low, you might run out of juice before you can power down. Most UPS devices are designed to provide 10 minutes of power. When selecting a UPS, you need to look at the VA rating — or amps multiplied by voltage (240v). The amp rating should be listed on your computer. Add up the VA ratings of everything you will connect to the UPS, then purchase a UPS with a VA rating 20-25% higher. If you are a home PC user, look for a UPS with a 1000-1400 VA rating.
Choose a good length Of Backup time
Don’t expect your UPS to keep your PC running all day. Most UPSes are engineered to provide you a backup time of around 10 to 20 minutes. What they essentially do is save your work when there is a power outage and avoid an abrupt shutdown that could mess up your computer settings. Choose the UPS that meets your backup time demands.
Other features of a UPS
When you are buying a UPS, ask the vendor about more features than just power. This will help you in finding the UPS which has that one additional option that will help you in your buying decision. Of course, the best feature is Automatic Voltage Regulation (AVR) which isolates your PC from voltage fluctuations that lead to computer disturbances. A UPS with AVR conditions the incoming power before being fed to the PC’s Switch Mode Power Supply (SMPS). Most UPSes also automatically initiate a scheduled shutdown sequence when the power is lost, after saving your work, to prevent damage to the computer hardware.
Warranty
Obtain a guarantee before buying a UPS. Undue delays in replacements can affect business. Some vendors offer onsite warranties, where they replace the batteries at your place. If you are planning to use the UPS at work, go for a longer warranty term.
Battery replacement
The general rule is three years. But if you are experiencing low backup times more frequently, you could get the battery replaced immediately if it’s under warranty. If you are facing no problems, expect your battery to work for three years. Its advisable to buy replacement battery cartridges while you are buying the UPS. These cartridges will breathe new life into UPS systems suffering from expired or weak internal batteries.
Power up
Contrary to the myth, its perfectly fine to leave the main switch on even when you are no longer working and the computer is shut down. However, its best to pair your UPS with a voltage stabilizer for additional safety.
Software reporting
The software provided with the UPS is not always accurate with its reports. So don’t listen to it when it says your battery needs to be replaced even though you’ve never experienced low backup times. These faulty reports shouldn’t worry you because they may be trying to get you to purchase the company’s product more frequently (a common problem with print cartridges.) The software is good at its essential function of shutting down the PC properly and saving your work, but you may be the best option to determine whether its time to change the battery.
Tips and tricks
Do not overload the UPS by, for example, connecting external devices like the printer, scanner and the fax machine. NEVER plug a printer into the battery backup system. To optimize the charge of your batteries, you should discharge them completely at least once a month. And lastly, make sure the UPS is properly grounded all the time to prevent any electrical disasters.
Shop around compare specifications against Price..
Standby UPSs are available in the range of 300VA to 500VA for office use, and up to 2KVA to 3KVA for workstations and large servers. Inexpensive standby UPSs ranging in price from $50 to $125 are used by millions of users of personal computers all over the world. Some of them include brands like Belkin, American Power Conversion (APC), Cyber Power, Data Shield, EFI, NCR, SAFE, Pacific Power, Sola and UP Sonic.
Conclusion
Basically , there are two kinds of UPS systems. The Standby Power System (SPS) and Online UPS System. If you are a home user, go for the relatively cheaper SPS. The price of an online UPS is three to five times that of a standby UPS with the same power rating. For servers, buy an online UPS (online means outgoing power is always drawn from the battery). Expect to pay between $150 and $1,000 for an online UPS. The higher the VA rating, the more you’ll pay. You might also want to consider buying one with advanced-battery features. These features include intelligent-battery management, battery-replacement indicator, and hot-swappable user-replaceable batteries.
Remember
An UPS isn’t intended to power you through a blackout.. For that, you would need a generator. However an UPS is a cost effective way to let you save your work and power down safely.

Safety Switch, AKA RCD Breaker. Your first line Defence for Electrical Safety

Safety Switch 101
The best single safety investment you can make for your Workplace or dwelling is to buy a Safety Switch. Installing a Safety switch is the most effective method of preventing injury or death caused by electric shock. A safety switch works by detecting tiny differences in current through electrical wiring, and it can detect a potential path to earth. Take the example of a person holding a faulty appliance that has an electric charge thereby providing a path to earth. A truly effective Safety Switch will detect that leaking electrical path and shut all the power down in mere milliseconds, quite often before the sensation of electrocution is felt, thereby preventing a harmful or potentially fatal electric shock. Safety switches are Electro-mechanical devices and over time can be subject to failure. They should be tested regularly to make sure they are in working order.
Safety Switches can be prone to trip under certain conditions… There are a number reasons why a safety switch will trip. The Top 5 reasons are:

IMG_2847
An Appliance Fault
When an appliance becomes damaged or develops a fault, it may start to leak excess electrical current. This excess current will be detected by the safety switch and cause it to trip. The easiest way to determine if this is the problem is by unplugging all electrical appliances at the power point, resetting the safety switch and then reconnecting the appliances one by one until the faulty appliance can be identified. Always use caution when dealing with possible faulty appliances and if in doubt contact an electrician.
Intermittent or Nuisance Tripping
As the amount of electrical appliances we have in our home increases, so does the likelihood of Nuisance Tripping. If there are a large number of appliances plugged in to the home at one time and a small amount of current leaks from each, the current adds up to become more substantial. This may mean that the safety switch is continuously on the verge of tripping. If there is the tiniest change in electrical current from the electricity company this can push the switch to its limit causing it to trip. This can become more of a problem in older homes where the electrical wiring is not in good condition. Limiting the amount of appliances plugged in at one time can help minimize this type of tripping.
House Wiring Fault
Faulty wiring poses the most threat to our safety and presents the worst fire risk. Fortunately, a safety switch dramatically reduces these risks. All wiring deteriorates over time and can become dangerous, so older houses are obviously more at risk. A safety switch will detect any fluctuation in electrical current caused by damaged wiring and trip, cutting off electricity immediately and stopping the wiring from burning out. A qualified electrician can assess your electrical wiring and may suggest repair or replacement.
Faulty Safety Switch
Sometimes the cause of a safety switch tripping can be the switch itself. As with any electrical appliance, a safety switch can become defective with age or mistreatment. Safety switches should be checked every six months to ensure they are working effectively. A qualified electrician can offer advice on how to do this, or do it for you if you are unsure.
Electrical Storm
An Electrical Storm can also be the cause of a safety switch going off. When lightning strikes your home, power lines or a power station it may cause a power surge which can cause a safety switch to trip. If this occurs, it is best to wait until the storm passes before resetting the switch. If in doubt always consult an electrician.
Without the right safety equipment and safety precautions, electricity can be deadly. Always check with an electrician if you are unsure why your safety switch has gone off.

My Safety Switch has tripped… What should I do NOW !?

A Simple step by step guide to fault finding a tripped Safety Switch.

Note: Some types of appliances may cause incidental or nuisance tripping of your Safety Switch or RCD device. Typically Water Heaters, Electric Jugs and Kettles, Steam Irons, Dishwashers, washing Machines, Swimming Pool Equipment, Auto Defrost Refrigerators and Freezers.
Most Important: If your Safety Switch has turned off, it has done so for a reason. It has detected a leak of some electricity. This may be through a faulty appliance or it may be a fault in the house wiring. These instructions will help you find that leak.

1. First try to turn the Safety Switch on.[Marked Residual Current Device]
2. If it stays on then the fault was intermittent or transient and we can do nothing at this stage. Refer to Note above.
3. Think of what you were using at the time.
If the Residual Current Device trips off again, got to point 5.
4. Turn on the Residual Current Device.
5. If it won’t stay on then you will have to unplug all appliances!
This includes any outside power points or power to outbuildings.
6. At this point the Residual Current Device should stay on. [If not you will need to call an Electrician.]
7. If the Residual Current Device stays on then turn the Circuit Breakers on one at a time.
8. When you come to the leaking circuit, the Residual Current Device will turn off.
9. Unplug all appliances that are plugged in to power points that do not work.
Turn the Residual Current Device on. If it won’t stay on then you will have to call an Electrician.
10. If it stays on, then one of the appliances you have unplugged is faulty. Plug the items in, one at a time until you find the faulty one.

Remember Do not fix any Electrical device yourself, give the device to a suitably qualified electrical repair workshop or if under warranty consult with the manufacturer for the possibility of repair under those warranty conditions.

Understanding the Danger of Electrical shock

The 2  Major hazards attributed to electrical equipment and wiring are electrical shock and fire. Electrical shock occurs when the body becomes part of the electric circuit, either when a part of your body comes in contact with both of the active component (Active/Neutral)wires of an electrical circuit, or one wire of an energized circuit and the Earth wire (or grounded wire)…., or a foreign conductive object that has become energized by contact with an electrical conductor.

The severity and effects of an electrical shock depend on a number of factors, such as the pathway through the body, the amount of current, the length of time of the exposure, and whether the skin is wet or dry (ie sweat). Water is a great conductor of electricity, allowing current to flow more easily in wet conditions and through wet skin.

240V can kill!The effect of the shock may range from a slight tingle to severe burns to cardiac arrest. The chart below shows the general relationship between the degree of injury and amount of current for a 50-cycle hand-to-foot path of one second’s duration of shock. While reading this chart, keep in mind that most electrical circuits can provide, under normal conditions, up to 20,000 milliamperes of current flow. So only a very small percentage of current leaking to earth can cause harm if touched by your body… as little as 30 milliamperes of current can KILL !!!

Current
Reaction
1 Milliampere Perception level
1-5 Milliamperes Slight shock felt; not painful but disturbing
6-29 Milliamperes Painful shock; “let-go” range
30-150 Milliamperes Extreme pain, respiratory arrest
151-4,300 Milliamperes Ventricular fibrillation
4,300+ Milliamperes Cardiac arrest, severe burns & even death

In addition to the electrical shock hazards, sparks from electrical equipment can serve as an ignition source for flammable or explosive vapors.

Even loss of electrical power can result in extremely hazardous situations. Flammable or toxic vapors may be released as a chemical warms when a refrigerator or freezer fails. Fume hoods may cease to operate, allowing vapors to be released into the work area.  So take care with your electrical equipment and consider all contingencies in the operation of that equipment.

What you need to do to manage Electrical Risk in the Workplace

Managing electrical equipment and installations

A business needs to ensure that:

  • power circuits are protected by appropriately rated fuses or circuit breakers
  • electrical leads are not arranged so that they are easily damaged, run across floors or doorways, or over sharp edges
  • only leads and tools designed for wet or damp conditions are used in those conditions
  • circuits where portable equipment may be connected are protected by RCDs
  • if any current protective device (RCD or circuit breaker) is triggered, the system is not re-energised until the reason has been identified by a competent person
  • equipment identified as unsafe is disconnected or isolated and labelled as unsafe and not reconnected until it is repaired and tested as being safe
  • regular visual inspections and testing of electrical equipment, including RCDs, occurs. The nature and frequency of inspection and testing will vary depending on the electrical risks.

Fire Hazards heaters, clothes dryers & electric blankets

Each winter heaters, electric blankets and tumble dryers cause a large number of house fires in Australia. Have you checked and kept up your maintenance by simply following these valuable tips

Removing hazards and safe use of heaters

  • Never leave heaters unattended. If a fire starts it could spread through your home before you are able to respond.
  • Keep flammable materials at least a metre away from the heater. The majority of house fires are caused by people hanging clothes or towels to dry on or in front of the heater. Clothes, upholstery, curtains and other material that could catch fire should be kept more than a meter from any heater at all times.
  • Make sure portable heaters are secured upright and not left in locations where people or pets could knock them over.
  • Avoid using portable heaters on table tops unless they are secure and designed for that purpose. There is a risk of heat damage to the table top and if it falls off it could damage the heater and start a fire.

Electric heater safety tips

  • Don’t plug electric heaters into powerboards, double adaptors or extension cords with other appliances. Heaters consume large amounts of power and may overload the supply and cause a fire.
  • Before using an electric heater check the condition of the appliance and power cords for obvious damage. If there is damage contact an electrician or the service technician to fix it.

Gas heater safety and correct use

  • Never use gas heaters designed or marked for outdoor use inside. They are a fire risk and can also release toxic gases which can accumulate inside and potentially harm you. Using LPG cylinders indoors to provide fuel for unflued heaters or other gas appliances is dangerous and is not recommended.
  • Unflued heaters must not be used in bedrooms, bathrooms or small rooms that have no permanent ventilation. Toxic gases can build up inside and potentially harm you.
  • Never use your gas oven or stove as a room heater.
  • Always check your gas heater is working correctly. Signs of problems with gas heaters may include difficulty when lighting, yellow flames, unusual smells or noisy or inoperable fans.
  • Regularly service your gas heater according to the manufacturer’s instructions. Always use a licensed gas fitter for this task.

Clothes dryer safety

  • Ensure that the lint filter is cleaned regularly. Lint that has built up can catch fire.
  • Follow manufacturer’s instructions and only place suitable materials into the clothes dryer.

Electric blanket safety

Do you really need them they can be dangerous and not certainly not recommended for use with children (eg Bedwetting) If you really need to use one then every year take it out and give it a thorough check.

  • Electric blankets should be rolled when stored away. Folding an electric blanket can damage element wires within the blanket
  • When using a blanket for the first time after storage, lay it flat on the bed and check for hot spots as it heats up. Only add sheets once you are sure the blanket will operate safely at a maximum temperature.
  • Electric blankets that are not properly maintained can cause fires.
  • Avoid using double adaptors or power boards wherever possible.
  • Older electric blankets might be damaged and may not have the safety features of modern blankets, so consider replacing them.
