Fortunately I didn't burn it down. I am sensitive to flickers when there should be no flickers right along with noise where there should be no noise, etc. I had traded out the oil in the Generac along with the filter, and was going to leak test and load test it. Off with the main breaker, fire up the genset, swap the transfer switch, turn on the main breaker. Oops, the trouble light flickered a bit, but the bulb isn't loose. Off with the main breaker, go reset the transfer to shore, turn the breaker back on. There is no light fixture in the cabinet where the transfer switch lives.... but there's light in there. OFF with all the power, and pull out the switch. Fortunately the load side contact burnt up, not either of the feed sides. And, it was in fact sized properly - 125-177V 30A. And I'm sure the Norris owners manual for the coach had in large black letters "DO NOT SWITCH SOURCES WITH POWER ON", which advice left along with the
book. 25 years or so of POs switching it under load finally did for it.
The point is, when you add the fire supression to the engine room and the rear bays, you haven't covered it all. You need a couple of fire extinguishers in the living area as well. Here, dry chemical extinguishers work fine. You're blowing them on wood and carpet which vacuum up easily. CO2 will work also. Spend your foam money where it's needed. They're house trailers inside, and if you get them lit, they'll burn like one. In a former life one of my tasks was to interview fire chiefs in small towns and map occurrances of house fires. Since I lived in one, I always asked about house trailers. I >never< found a fire chief who would admit to having put one out. Let your GMC burn for three or four minutes, you ain't gonna put it out either.
The second point is, things electric aren't supposed to flicker - or run with hiccups - or humm with crackles in the hum. Find out why, as opposed to waiting till the light goes on where there ain't no light. This is why I'd asked about a diagram for my coach - I KNOW the lights aren't supposed to flicker. I think I figured out why.

Same switch in the same place. I'd recommend anyone with a Norris or Midas upfit and this system replace that switch on GPs if it hasn't already been.
