Top benefits of having Ground Fault Circuit Interrupters

GFCI or ground fault circuit interrupter switches protect our homes and everyone in it from receiving electrical shocks. They work by being able to compare the very small differences in the input current from the positive or hot side with the output current on the neutral or negative side. Talk with your friendly local electrician on the Gold Coast about your individual needs.

If the device detects just a few milliamps of leakage or difference, then it will shut off the power to that device. This can happen in 20 to 30 milliseconds which can save a person from serious electrical damage.

Where should a GFCI device be installed?

A GFIC device should be installed on any circuit here moisture or water is present as this moisture greatly increases the likelihood of an electric shock happening such as:

  • Kitchens or any size
  • Laundries and anywhere there is either a wash tub or clothes or washing machine
  • Utility areas where water may be used
  • Bars and service areas
  • Boathouses and bathing sheds
  • Pools, hot tubs spars and sauna’s
  • Decks and any outdoor areas including covered outdoor areas
  • Workshops, garden sheds, garages and any accessory buildings
  • Basements, crawl spaces and anywhere where water can get to

These are the top benefits of having a GFCI device installed in your home:

  • Shock prevention

The most obvious thing a GFCI device does is prevent electrocution or shocks using its inbuilt sensors. This monitors the electrical flow and instantly shuts down the power supply it a fault is detected preventing an electrical shock.

Fire Protection

A ground fault circuit interrupter does just what its name implies, it detects any electrical flow that leaves a circuit to the ground, a major cause of electrical fires. Your fuse link or circuit breaker will also do this, but having your electrical circuits protected by GFCI devices you will enjoy peace of mind knowing and never having to worry about having an electrical fire in your home.

Prevents Damage to Appliances

Many electrical appliances are used constantly so over time they suffer a reasonable amount of wear and tear. This is not only on the outside, but can extend to the internal wiring where the electrical insulation is prone to breaking down. This can cause a small amount of electricity to leak into the appliance and escape.

If the appliance outer area is made from a non-conductive material such as plastic, you’re unlikely to get a shock as you would if it was made from metal, but this leakage will begin to damage that appliance. One of the main reasons that a computer hard drive can fail is directly related to this issue of electrical current leakage

Having a GFCI device installed on the circuit will mean any electrical leak will be detected immediately and the circuit shutdown so no damage can occur, preventing the loose of any important information stored there.

Your electrician on the Gold Coast is the person you should contact to find out about having GFCI devices installed on your electrical circuits to protect your family, home and all your appliances. They will completely eliminate the worry of electrical shocks and fires in your home.

Benefits of having Knob and tube wiring in your home

If you have an older style home it may have been wired using knob and tube wiring. Talk with your local electrician on the Gold Coast about the condition of the wiring. This is a form of wiring that used porcelain knobs and tubes to insulate the wires around your home.

This form of wiring, although not used anymore in Australia had some benefits to the consumer. Mainly that it was much cheaper to purchase and install than any other types of wiring systems before the 1950’s. The wires were installed under floors, in ceilings and in the lining of walls where they were not accessible or posed a danger of electrocution.

This system worked well for loads of up to 10amps as it kept the wires cool as the heat generated as the current passed through dissipated quickly.

Labour

When used (Pre 1950) labour costs were much lower than the present day and the most expensive part of any job was the materials. Once the labour cost increased to the stage where today it is much more than the normal material costs, as installing knob and tube wiring is very labour intensive it became much less popular and eventually stopped being used.

Porcelain

Porcelain insulators are extremely resilient with a very long lifespan that provides excellent insulation protection. The porcelain knobs help prevent the wires from being over tensioned when they are installed, allowing the wires to remain trouble free for a long time.

Disadvantages of Knob and Tube Wiring

There are only two wires the phase, hot wire or positive and the neutral. In the 1960’s the third wire, a ground wire was introduced for safety. This ground wire protects lives and property from surges and overloaded circuits.

Insulation

The knob and lube system requires that the wires are not covered with any type of material such as insulation or in the case of pests, having nests built or stacked around them so they are not able to cool down adequately in the air.

The natural rubber insulation on the wires over time breaks down and no longer provides adequate protection, allowing to the possibility of electric shocks and short circuits

Increased Power Usage

The power needs of homes and other building has dramatically changed since knob and tube wiring was used. Most of these types of circuits were used for lighting as there were few electrical appliances. A 10 amp knob and tube wiring with a 60amp electrical system is just not able to cope with the demands of a modern home. Ask your friendly electrician on the Gold Coast to check your home and the wiring.

Most homes today require between a 150 to 250 amps service capacity and if your home still has knob and tube wiring it was probably modified improperly and poses a fire of electrical threat.

Your friendly local electrician on the Gold Coast can advise you on the best way to ensure your home is safe.

Talk with your friendly local electrician on the Gold Coast about your home’s wiring if the house was built before the 1960’s to ensure it’s safe as there are really no benefits to keeping the old knob and tube wiring apart from saving replacement costs
