back up generator options

[megloff11x]

I have a couple of co-workers who want to install back up generators in their homes. I referred them to the local electrical supply places to get referrals to the local home electrical contractors - I do machine/industrial, and only know enough to know to hire someone who knows what he's doing and isn't as physically decrepit as I am on most home stuff.

If memory serves your options are:

1. A system that automatically disconnects the mains during an outage and starts the generator.

2. A system that makes you throw a switch so that either or can be on but not both as this would be very bad, and you have to manually start the generator.

3. You direct plug important stuff into a standalone generator instead of your home outlets.

I know I've seen this discussed before and maybe even on one of the emails, but my memory is as a sieve.

Can anyone recommend a system or systems of each type, ballpark costs, and the appropriate code articles? I'll pass it on and let them hire a professional.

Really, it comes down to how much convenience they are willing to pay for.

I would be content with a 5000W generator and a manual transfer switch. That would do me fine, but I have small aspirations.

If someone wants (and can afford) the convenience of a system that turns itself on when needed, and can power the whole house, then they should go for that.

It's strongly driven by money and preference, so there is no catch-all answer to your question.

I would avoid the Companion generators, because I bought one and it never ran right, before I let it sit and become a boat anchor. I am without, if we lose power at the moment. Hondas are nice, from what I've seen. Generacs are pretty darned snazzy. That's about all I know about brands.
