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

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.
