Backup Power

Backup Power Generators,

Losing power due to blackouts caused by the weather or unreliable power supply can be a frustrating time both in the home and business. A backup generator can be used to power essential items such as lights, fridge/freezers, and power points to charge phones, radios and laptops.
Before purchasing a generator you must consider what it will be used for. You will also need to take into consideration the size of generator needed to supply the items you would like to power. There is a large range of generators available on the market and those available for home backup power are compact, quiet and efficient.

Type Of Generator

The first question to ask yourself is will the generator be:
Used with directly connected plug-in appliances; or
Connected via a plug and appliance inlet to your home via a changeover switch (installed by a qualified electrical contractor); or
A hard wired connection to your home via a changeover switch (installed by a qualified electrical contractor).
If you will be purchasing a generator for use with plug-in equipment like hand held equipment (e.g. a drill) you will need to purchase a generator that incorporates an RCD (Safety Switch).

If you will be purchasing a generator to plug in or hard wire directly into your home via a changeover switch, the RCD should not be incorporated into the generator.  In this case the equipment in your home will be controlled by the RCD’s installed in your switchboard.  Please note: To ensure the safety of the installation it is advisable to install a hard wired generator into the switchboard, this will eliminate the risk of someone using the plug in generator (which does not incorporate a RCD) for any other use.

The Lead

If you are using a plug in type generator the supply lead from the generator to your house will need to be the correct size for the generator – if unsure check with your electrical contractor.
The supply lead will also need to be installed to be protected against any mechanical damage, for example installed in a suitable wiring enclosure.

Where To Put The Generator

Gas or fume poisoning is not to be taken lightly, therefore generators need to be placed in areas where exhaust gases, smoke or fumes cannot reach dangerous levels or enter any areas that people may occupy.  Generators must also not be exposed to the weather unless they are suitably protected.
Care must be taken with the positioning of the generator to make sure refueling can be performed easily.  High temperature surfaces or equipment that may emit arcs or sparks may cause ignition when refueling.
