With hurricane Harvey and now Irma. I am sure some are thinking about generators.
If you wire your generator into the house . Make sure you use a proper transfer switch to.make.sure you are isolated from the power grid.
If not, you risk.the lives of those working to restore power to your community. A young man lost his life earlier today from what is being speculated was a generator backfeed.
Electricty doesn't.Stop.at your house if you are not isolated. That transformer.outside that steps.the primary 7200v down to 240v does not care where the power is comming from. And will happily take the power from your generator and step it up to 7200v.
