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

  1. Always replace a blown fuse with the correct fuse wire. Never use fuse wire that is heavier than the recommended gauge.
  2. Never use any other type metal or wire.
  3. If fuses keeps blowing, or a circuit breaker keeps tripping, check that your appliances are not faulty.
  4. 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 and RCD devices

Safety switches or RCD device look similar to circuit breakers and will have a test button to provide a test for the correct earth tripping of the device. The purpose is to 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. It is imperative that commercial premises have them installed and tested regularly.. New homes and Commercial premises 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  and these portable RCD should also be tested on a regular Basis!

Electrical Risk Assessment in test & tag

Electrical Risk Assessment is a necessary step prior to determining a Test & Tag interval of testing

After the work area has been determined as either electrically non-hostile or hostile, a regular inspection schedule can be developed. It is recommended that regular workplace safety inspections are synchronised with the checking periods which are required for electrical equipment.

Non-hostile electrical environment This is a workplace that is dry, clean, With equipment and leads are away from danger from sharps and flexing  or anything else that may result in damage to electrical equipment or the flexible supply cord. In accordance with Safe Work Australia: Code of Practice – Managing Electrical Risks in the Workplace, electrical equipment used in electrically non-hostile operating environments does not require tagging. It is sufficient to visually inspect equipment and cords for damage prior to use and thereafter on a regular basis.

Hostile electrical environment This is a workplace where the equipment or appliance may be subjected to events or operating conditions which could result in damage to the equipment or a reduction in its expected lifespan. What is a Hostile Environment? Is the electrical equipment, when used in normal operation, exposed to any of the following items that might result in damage to the equipment or reduction in its expected life span:

  • Mechanical damage?
  • Moisture?
  • Heat?
  • Vibration?
  • Corrosive substances?
  • Dust?
  • Sharps?
  • Grease/Oil?

If ‘YES’ to any of the above, the environment is considered ‘hostile’ according to the Australian Standards AS/NZS 3760  for testing & tagging.. Just as a general guide see the table Below… It is taken from the Australian Standards AS/NZS 3760  for testing and Tagging and it forms the basis of State and Industry testing and tagging requirements. Below is a key for identifying the categories in the table and the type of environment in which they are found.

Why does my Safety Switch keep tripping?

Electrical Safety Switch Tripping possibilities

Electrical Safety Switches  are RCDs ( Residual Current Devices)  that remove the supply to an electrical circuit when the circuit under protection has detected a leakage to earth. The RCD/Safety Switch responds in mere mili -seconds; avoiding an unsafe condition and thereby potentially preventing electrocution or Fire hazard.

Possible Causes Of Safety Switch/RCD Tripping

Faulty appliance – unplug all electrical appliances, does the RCD reset OK? If the RCD resets OK plug the appliances back in one at a time. Reset the RCD as you plug each appliance back in to find the faulty appliance.

Items with motors or pumps starting – many items with motors or pumps, for instance showers and pond pumps, cause momentary electrical spikes that are big enough to trip RCDs. Seek advice from a qualified electrician.

Older washing machines – aging washing machine heating elements can cause momentary electrical spikes that are big enough to trip RCDs.

Certain wash cycle phases – some cycles of the washing machine, for instance the spin cycle, can cause momentary electrical spikes that are big enough to trip RCDs.

Certain dishwasher cycles – some parts of the dishwasher cycle draw a lot of current, a faulty component, for instance the motor, can trip an RCD.

Overloading a washing machine – too many items in a washing machine can cause certain wash cycles, for instance the spin cycle, to trip an RCD.

Fridges and freezers cooling – the fridge or freezer cooling motor starting.

Turning an heating element on after a long time of being off – moisture in heating elements can trip an RCD, for instance in a sun bed or electric fire. Try resetting the RCD a few times so that the heating element can cause the moisture to evaporate.

Moisture in outside electrical distribution boxes – remove the supply and dry the distribution box. Check the weather seals have not perished.

Moisture in outside electrical sockets – remove the supply and dry the electrical socket. Check the weather seals have not perished.

De-frost timer on a fridge or freezer – a faulty defrost element on a fridge or freezer can cause ‘nuisance’ RCD tripping.

Water heating elements – faulty water heating elements can cause nuisance RCD trips when thethermostat tells them to heat the water.

Moisture in wiring – moisture in the electrical wiring is a common cause of RCD trips. Have you just emptied a bath? Taken a shower? Is it raining – rain can get into the electrical wiring under the floors or in the loft.

As you may have found this list contains certain  conditions that may give clue to an RCD tripping. In most cases this concerns appliances or situations that involve at least one or a combination of  three conditions 1) Moisture leaking electricity to earth in the appliance or premises wiring. 2) A heating element that is either faulty or drawing sudden electrical surges. 3) An appliance with an electric motor that is either faulty or drawing sudden electrical surges.

If you have trouble sourcing constant or intermittent RCD/Safety Switch Tripping then Contact us and we can send a Qualified Electrician around to check it they can source and fix it on the spot.

Workplace Power Tool Safety Update:

Workplace Power Tool Safety Tips

Introduction:

Power Tools are time saving convenient devices that assist us in building and maintaining our World. However it also contributes to large amount of injuries recorded in Australia every year. Many of these injuries are often easily avoidable and attributed to carelessness, a lack of proper tool maintenance or simply not reading the operating instructions.

Power Tool safety 101

  •          Wear safety gear

Always wear the appropriate safety gear, particularly safety eye wear. Flying shards and debris create unpredictable trajectories and a sudden occurrence can not only cause damage to your eyes but force you to loose control of the powered tool you’re operating.

In addition to eye wear, workplace noise is also often overlooked. However the cumulative time of exposure to above normal decibel levels in the workplace can do irreversible damage to your hearing.

Other safety gear such as gloves and appropriate clothing/ safety footwear are just as important, and should be part of formal personnel safety plans.

  •          Read the operating instructions

Being unfamiliar with the safe operation of the power is often the cause of power tool injuries. Before using anew power tool ensure you read the operation, safety and maintenance instructions of the particular tool. The key here is to familiarize both yourself and your team with new equipment when it is introduced to the fleet or job. In particular, built in safety devices and kill switches should be highlighted. Remember to also use a RCD power breaker/power board when working with high powered tools.

  •          Electrical Safety and Power Tool operation

When workers use portable power tools and electrical leads that are electrically faulty or damaged they may suffer electrical shock, which could result in death, heart problems, internal organ damage or burns. To reduce risk of injury or death, electrical leads and power tools should be visually inspected prior to use, and avoided if equipment appears to have been modified or damaged. Tools should only be plugged into socket outlets that are protected by a residual current device (RCD) or a portable RCD is used.

Electrical hazard found on Site

Cut Lead Exposed wires found on Circular Saw at Warehouse

Workers should ensure power circuits are protected by the appropriate rated fuse or circuit breaker to prevent overloading and potential overheating. Electrical leads should be arranged so they do not run across the floor or ground, through doorways and over sharp edges. Where the lead arrangement is dangerous, lead stands or insulated cable hangers should be used to keep leads off the ground. Leads and tools should never be used in damp conditions unless they are specially designed for use in those conditions. Ensure your Tools are Tested and Tagged regularly to pick up electrical faults and potential hazards.

  •          Report all accidents

It’s important to report all accidents and injuries in the workplace. This not only creates a culture of continuous learning, but also helps to future proof against lengthy compensation claims.

In South Australia, It is a legal obligation to notify Safe-Work SA of any work-related injury that requires treatment as an inpatient in a hospital immediately after a workplace  injury (disregarding any time taken for emergency treatment or to get the person to hospital).If you are reporting work-related injuries or incidents to Safe-Work SA the 24 hour Emergency, Dial 1800 777 209.
