dtontarski Posted August 20, 2006 Report Share Posted August 20, 2006 I'm scheduled in inspect a home with a back-up generator. Any words of wisdom regarding the inspection of a home with one of these systems? Quote Link to comment Share on other sites More sharing options...
charlieb Posted August 20, 2006 Report Share Posted August 20, 2006 1. Unless you are well versed in their installation and wiring defer it to an electrician. 2. Have the engine inspected by an appropiate service co. 3. Request the owner produce service records on the unit's maintenance. Quote Link to comment Share on other sites More sharing options...

Any words of wisdom regarding the inspection of a home with one of these systems? If you do nothing else, confirm that there's a transfer switch installed to prevent parallel operation and to prevent the generator juice from travelling back over the service wires and frying a lineman. Otherwise, I agree with Charlie's advice. - Jim Katen, Oregon - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
kurt Posted August 20, 2006 Report Share Posted August 20, 2006 I've seen about a half dozen, & I've still not been able to even verify the presence of a transfer switch, or anything else on any of the systems, re: Charlie's #1 comment. My customer's have not been upset w/me at all when I've told them I'm clueless about them; they're actually real happy turning the whole thing over to an electrician.

charlieb Posted August 20, 2006 Report Share Posted August 20, 2006 Transfer switch = Box with lotsa wires between the panel and the generator.[^] That's as far as I go. Let the sparky ID the circuits supplied and the details. Quote Link to comment Share on other sites More sharing options...
hausdok Posted August 20, 2006 Report Share Posted August 20, 2006 Hi, I see about a dozen a year. They usually have two setups here. The first is a setup with a manual transfer switch that, when switched, kicks off the main breaker and prevents accidentally having parallel operation as Jim describes. The other involves nothing more than a series of toggles and screw-in fuses in a separate panel that's wired into critical circuits in the home. With this setup, you have to first turn off power to the house at the main disconnect and then, after you're sure the main breaker is off, start the generator and individually turn on each circuit and rely on the fuses for overload protection. These bother me, because if the danged thing is running and an uninformed person hears on the radio that the power is being worked on, I can see that person walking over to the panel and throwing that main breaker to see whether it's been fixed yet, without shutting down the generator first. About 3 weeks ago, I saw on the news that there was a lineman electrocuted here but I don't remember the circumstances. My first thought was that someone got hit by one of these generators.

dtontarski Posted August 20, 2006 Author Report Share Posted August 20, 2006 Thanks for the advice. I have seen a few of these in the past (prior to discovering this forum) and deferred these to an electrician, with mention of service requirements and hazards associated with improper use. It's great having this resource to tap into the collective wisdom of its members. Quote Link to comment Share on other sites More sharing options...
hausdok Posted August 20, 2006 Report Share Posted August 20, 2006 Oh yeah, I'd meant to send you to this article. I wouldn't share it with clients, but it provides a little bit of insight into how these things are installed and how it's setup. http://www.popularmechanics.com/home_im ... 75631.html OT - OF!!! M.
