How to Add a Transfer Switch to the Main Breaker Panel

     Electricity enters our homes through the main breaker panel. The trouble is that when there is a power cut we aren't able to use any of these appliances, and that's where a generator comes in handy. A generator is a gas powered engine which is attached to a motor, the engine will turn the electric motor which will in turn generate an electric current.

A transfer switch is a type of switch which is fitted inside your electrical breaker panel. It connects to your normal AC power supply and when it senses a power cut it will divert all of the load to the generator. If you plan on using a generator as a backup source of power then you will first need to install a transfer switch to comply with building regulations.

If you're not confident at working with electricity in your home then you must talk to a qualified electrician. A qualified electrician will be able to complete this job safely and quickly.

Tools and Materials Needed

• Transfer Switch
• Phone
• Screwdriver

Step 1 - Choosing a Switch

There are a few different types of transfer switches, there are automatic and manual switches. Automatic switches will be the most convenient because these are capable of turning the generator on automatically when they sense a power cut. When the power cut is finished it will then automatically shut the generator down and use AC power from your utility company.

Step 2 - Shutting off the Power

It's essential that you shut off the power before doing any work - unlike many other projects it's essential that you phone the utility company to get all of the power in your home shut off. This is because you will remove the entire electrical panel. You will need to contact the electricity company in advance to get this sorted out.

Step 3 - Installing the Power Transfer Switch

The power transfer switch now needs to be installed either to the right or left of the load input inside the electrical panel. It should be located approximately 18" away from anything else in the box.

Step 4 - Wiring the Switch

Take the protective covers off the center load and remove the main power cable, you then need to connect a cable from the meter to the transfer switch; this should be fixed to the commercial input.

Ensure that all of the locknuts are securely tightened. Make sure that all of the wiring is as neat and tidy as possible, any stray wires could mean that your home won't get power.

Step 5 - Connecting the Generator

Connect the generator to the transfer switch using wires and in a similar fashion. Once you have connected and grounded the generator you can then call the power company to get the power switched back on.
