I'm thinking of installing a backup generator. Got an estimate over the phone from one guy who told me the whole package, including install would start around $15K, well after I recovered from the shock, I'm thinking about doing most of the work myself (the gas portion I will leave to a plumber) but I can run the conduit and wires from the utility room to the generator (about 75') myself and save some bucks.
The unit I'm looking at is a Generac 11kw LNG unit with a 200A whole house auto transfer switch. The two legs, neutral and ground wires (I figure 6AWG THHN because the unit has a 50A breaker) and the five signal wires (18AWG) should be able to run in 1" Sched. 40 PVC conduit (my calculator puts it at a 27% fill rate).
Does anyone know if I can run the gas piping and the elec. conduit in the same trench?.
I'm also concerned about the 90 degree conduit bends - do I have to use those 90 degree PVC elbows with the large radius bends or can I use one of those conduit bodies (or even something else)? - there's a couple of bends in my basement ceiling that may need to be tighter than the standard elbows.
Thanks!
