Power Points: a basic guide
Installing a power point might seem like a simple job for an electrician to carry out, but there are a lot of behind-the-scences calculations we must consider before installation. Every building contains a number of separate power point “circuits” – individual tracks of power running behind the walls. As qualified electricians we must assess what electrical products are currently using a circuit before adding another powerpoint. As a rule of thumb we only try to put eight double power points per circuit to prevent overloading the circuit. This reduces the risk of overheating the electrical system (overheating or overloading a circuit has been linked to electrical fires).
It is always best to keep a home’s kitchen and laundry power points on separate circuits, as heating products in these rooms (ovens, dryers etc) tend to draw a lot of power.
All power points should be protected by earth leakage devices (commonly known as safety switches) which are fitted in your building’s switchboard.
Surge protection devices – an additional device fitted to your switchboard – can also preserve the power points and the equipment plugged into them. These devices limit the amount of voltage (240 – 250 volts) transferred through the power point.
