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

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.

What to look for when Buying a Smoke Alarm

 Which Type Of Smoke Detector I should buy?

Photoelectric or Ionisation?

The latest advancement In Smoke Detection Technology is the Photoelectric alarm they are widely regarded as being superior to ionisation alarms in most aspects. Not only do they respond faster than other alarms  and are less likely to cause annoying false alarms. Photoelectric alarms are particularly effective at detecting smouldering fires, which provides the earliest possible warning of a fire developing in an enclosed area.

If a smoke alarm has symbol a radioactive warning symbol, then it ionisation smoke alarm.

How many do I need to buy?

It is generally recommended that you should install smoke alarms in all rooms where people sleep and the hallways leading to sleeping areas.

In most states of Australia residents must have at least one working smoke alarm installed on each level of their home. This includes owner occupied, rental properties, relocatable homes, caravans and campervans or any other residential building where people sleep. Contact your Local Fire Authority

Are there approved smoke alarms?

The Australian Standard symbol on the packaging shows if the alarm is approved and safe.Smoke Alarms must meet the requirements of Australian Standard AS 3786.

Hard-wired or battery operated?

In some circumstances your alarms cannot be hard-wired, then it is recommended that these photoelectric alarms run on 10-year lithium batteries. Inbuilt 10-year lithium batteries last as long as the smoke alarm so you don’t need to worry about replacing them every year – you simply replace the entire smoke alarm unit once every 10 years.

Hard-wired smoke alarm

A hard-wired smoke alarm consists of a 240-volt smoke alarm connected to a home’s electrical system with a battery back-up power supply.

Battery operated smoke alarm

Most smoke alarms come with a battery but not all batteries are the same:

  • 10 year lithium batteries: These batteries are recommended and last as long as the smoke alarm.
  • Lead or alkaline batteries: Need to be replaced yearly.

Where can I buy them?

Available at most major supermarkets and hardware stores buy approved smoke alarms meeting Australian Standard AS 3786.

Strobe light and vibrating pad alarms

Strobe light and vibrating pad smoke alarms are available for people who are deaf or hard of hearing. For more information contact the Deaf Society in your local state of Australia

So what is tested and what are we looking for when doing a Test and Tag regime?

Many of our clients organise regular test and tagging services simply because it is easier and safer.

A regular program of testing and tagging comprises of: (standard 10/15Amp 3 wire cabled appliance and plugged multi phase equipment)

A visual check to ensure the integrity of the Electrical cord and Appliance construction

  • The Technician looks for Cuts and breaks in appliance and power cables may present as an  electrical hazard.
  • An inspection of the integrity of the appliance housing looking for cracks and holes which may expose personnel to an electrical hazard.

A series of electrical tests are then conducted to detect the unobservable faults not found by the visual inspection process, and forms an integral part of the inspection/testing process.

The equipment is turned off to allow the technician access to the appliance plug. All tests are performed by disconnecting the appliance from the building power and connecting the plug to an insulation tester or a Portable Appliance Test-set built for the purpose of performing the tests automatically and uniformly. These Tests are:

  1. Earthing continuity test: (specifically for metal shrouded appliances) to ensure there is adequate connection between the earth pin on the plug of the appliance and the metal cover shrouding the appliance.
  2. Insulation resistance test: to ensure that no path exists with the appliance/lead for electrical current to transit from the active wires to earth.
  3. Continuity Loop test: to make the sure that the active circuit which powers the appliance has a good solid connection and in no way presents as an electrical hazard.
  4. Polarity Test: (only for items which distribute power: leads, power-boards, adapters etc) to ensure that the wires of an extension cord/power board appear the same order of connection at the plug as the do at the socket end.

Other Equipment Tests Include:

 RCD test to test the tripping time of a RCD to ensure your safety switch or RCD does work properly and switches off in a fault situation quick enough to save personnel from Harm.

3Phase Test: usually high powered workshop and building site equipment with multiple active wire connections (tests performed on 3phase test are similar to that of standard appliance tests outlined above)

Emergency Exit sign test: Tests the ability for an emergency exit sign to stay on when power is off 90 minutes is the expected time, if it fails to reach the expected time then the circuitry/ battery will be in need repair or replacement .

That is it, in a very basic overview if you need to know more please either contact us or contact Safe-Work SA (South Australia) http://www.safework.sa.gov.au/  1300 365 255 or The Workplace Safety Authority in your local area.

What Do I need Surge Protector or UPS?

Surge protectors … will protect your equipment from sudden  and dangerous in creases  or spikes in Voltage… They effective in shunting the excess power to earth in the event of the voltage increasing beyond 240 Volts (Australian Single phase appliance line voltage) … so that your equipment safe by making sure only a designated amount of power actually reaches your connected equipment. You can buy them as single-outlet units or multi-outlet power boards.

Surge_protection_board

An Uninterruptible Power Supply ( UPS) has that same qualities , but they provide a back-up power supply for a limited amount of time in case of a blackout or in some more sophisticated units  brown out protection (power goes low <240V) smoothing out any power fluctuations. This means if the power fails you have a good amount of time to save your work on your computer and shut it down normally.
