Generators for Homes

Talk with Calect to work out what services you want on at home (like how many lights and what type of appliances). We will work out the size of generator needed for you and get some options on equipment types.

Home Generator Size ChartA self-assessment of your electricity requirements to give an indication of generator sizing can be done by using the table below.

You need to have the ability to connect the generator into your electrical installation and then to swap between sourcing electricity from it or from the network and to do so without compromising the safety and operation of the electrical installation. A backup generator is a heavy paperweight if a manual cut over switch is not installed.

Calect will supply you with:

  • A flex to connect the generator into the electrical system.
  • A socket installed near the location of the generator.
  • A cut over switch to select the power source between mains power and generator power.
  • An earth rod and cable to bond the generator frame.

How to use a home generator

Home GeneratorA backup generator with a manual transfer switch is great, as long as you have one and know how to operate it properly.

 

 

Step 1 – Power Goes Out

If the power in your area goes out you should do nothing immediately. There’s often a good chance that the electricity will come back in just a few minutes. If the power hasn’t returned after 10minutes you should start getting the generator ready.

Step 2 – Manual Transfer Switch

Unless you’re simply going to plug appliances directly into outlets on the backup generator or use an extension cord, you’ll need a manual transfer switch fitted to your service panel. You should have a Calect electrician fit this. It’s a vital piece of equipment for using a backup generator. When the generator is plugged into it and it’s switched on, it takes those particular circuits that are hooked up to it off the grid.

You don’t want to have the circuits on the grid when you’re using a backup generator. If the electricity comes back on and you’re not off the grid there will be a huge power surge into your house that can severely damage your service panel and your appliances.

Step 3 – Service Panel

Before you plug in the backup generator, switch off each of the breakers and ensure every single one is off. When you’ve done this, turn off the main power switch for the house. This will ensure you don’t have a surge when you run the generator. Turn the manual transfer switch to the “Off” setting.

Step 4 – Starting the Generator

Most generators will start by pulling a cord. You might need to prime the motor first, but that’s not necessary with most modern backup generators. Before starting the generator, check that there’s ample fuel in the tank and top up if needed. Keep the generator in a well ventilated area. Outside is deal, depending on the weather. You should discuss this with Calect when we fit the manual transfer switch.

Step 5 – Connecting the Generator

Once the generator is running, take the appropriate cord and connect the backup generator to the manual transfer switch. Flip the power to the house back on and turn the breakers on one by one.

When you’ve done this you’re ready to turn on the manual transfer switch. It has three settings, “Off,” “Line” and “Generator.” Turn the switch to “Generator” and the circuits that are connected to the switch will come back on. Your backup generator will power the fixtures and appliances controlled by those circuits. When the electricity returns you can simply turn the switch to “Line” and power down your backup generator.
