Inverter Wiring

[Pete Masterson]

Greg,

I already discovered that the shore/generator power distribution box
doesn't affect the inverters. When my coach is stored, I turn off my
(home style) refrigerator _and_ pull the breaker (to turn off the
light). I normally have shore power available to keep the batteries
charged. I was surprised to notice, after unplugging the shore power,
that the light in the refrigerator was on (the inverters kicked in
automatically). Fortunately, I'd turned off the refrigerator, so only
the light came on. (I keep the door propped open a couple of inches
to let the inside fully air out so mildew won't grow in my normally
dry climate.) That's how I figured that the inverter power is tied
into the circuits it serves downstream from the main distribution panel.

I'll have to look at the KurtFiles CD -- I just got my copy a couple
of days ago, forwarded to me by my house-sitter -- but working time
on my coach is limited while we're on the road. I'm not sure I've run
across the switches (circuit 14, 24, etc.) you mention -- but I'm
going exploring in the inverter box in the next hour or so....
