I have read some other posts on this forum and others regarding the importance of installing a power transfer switch when connecting a generator to your existing wiring. My dad had a 6kw generator that we used when necessary. The process was simple:

1-Shut off the main breaker thus eliminating the possibility of backfeeding
2-Connect the generator to the electrical system thru a 220 outlet which was mounted close to the location of the generator.
3-shut down all unneeded circuits.
4-start the generator.

That was all there was to it. Am I missing something here? I was thinking of creating a similar setup in my own home and was wondering if anyone could share their experiences. Seems like a power transfer switch is an awful lot of money to spend when all you have to do is cut the main breaker.

Thanks in Advance,

Most utility companies I've dealt with require you to install a transfer switch.

Also, Article 702 of the National Electrical Code requires the use of approved transfer equipment.

Home made equipment does not qualify.

Yes you are absolutely missing something here. Basic electrical safety. Just because something works does not make it right. If you forget to switch the main breaker to the off position you might kill somebody working on the power lines. You need a proper transfer switch.

Listen to the wise words above. The National Electrical Code is very clear on this issue, as are all power companies. You must install (or have installed by a professional) a listed transfer switch. This is not as difficult or as expensive as it used to be. There are simple ones that can be purchased for about $200 and up. If you are not VERY knowledgeble with electrical installations this is a job best left to a professional, please call one. Mr. Electric
