My house has four 8 foot grounding rods and two water bonds. The plumbing is all galvanized, including the main running to the street, so the water bonds are secure. The generator wiring in the house will all be completely separate from the house wiring, but I had planned to ground the generator to a water pipe that is very close to where the generator will live. I went shopping for a double conversion UPS and discovered that they are pretty pricey. I didn't find any refurbs, but even a refurb would probably cost several hundred dollars. Rather than spend the money on a double conversion UPS I might be better off to use my existing UPS and get a better generator. The generator I was planning on getting is $1,000, but there is a very nice generator for $1,600 running off a Honda GX 390 engine that the manufacturer advertises as safe for sensitive electronic equipment: http://www.generatorsales.com/order/03369_alt.asp?page=H03369 The problem with this generator is that the seller has modified the Honda engine to run on natural gas, thus voiding the Honda warranty. The seller offers a two-year warranty, but is located on the east coast. On the other hand the GX 390 has been around for a long time and is wildly popular. There are enough parts on the net to build the whole engine from scratch, and at pretty reasonable prices. I am less concerned about the generator itself because the only thing you usually have to worry about are the brushes. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
