Wiring a transfer switch for generator

We have a portable generator (about 5000 watts). I hate having to run extension cords all over the house from the garage when the power goes out. The other problem with extension cords is not being able to hook up the furnace.

I know a little about manual transfer switches by visiting some other websites, but I was wondering if anybody knows of a good website for the do it yourselfer. I do have a friend that is an electrician that is going to help me, but I want him to just supervise, and not take up too much of his time.

I only want to run a few critical circuits.

Sump pump
sewage ejector pump
maybe a circuit for the tv and a light

Any help would be appreciated.

Below is a good DIY website.

You must use some sort of transfer switch, which will not permit the connection of the generator conductors to the utility conductors. Many hardware stores have small panels that act as transfer switches on a per circuit basis or group of circuits.

This is the device you need.


It is simple to hook up. You pick the six circuits you want to transfer. remove the wire from the breaker and connect to the wire from the transfer switch. Take wire from transfer switch and hook to breaker. Do it 6 times and you have it connected.
Here is the one they sell at home depot. It comes with the flex cable and wiring al ready to go.
