Default Crossover switch? Cutoff switch?

I use a Square D interlock kit on my 200A
QO panel with a 30A generator feed breaker. It works very well and
the OEM interlock kit was ~$60.


Umm ... the GE's that I found were $150. Why should they be so
much more? Anyhow, I just use the old turn-off-the-main-breaker &
back feed through the welder circuit.

Be prepared to catch a ration of **** for doing it that way . I
do it the same thru the shop subpanel , and every time it comes up
I get accused of trying to fry a lineman or something . Hmm , I
was just thinking , if a guy wired them up right a set of lights
could not only tell when the power came back on but could let you
synchronize with the grid for uninterrupted service .


They can spew that nonsense, but that's all it is. It is physically
impossible for your little generator to "fry a lineman" unless that
lineman violates his safety procedures. They *must* test and ground
every circuit conductor before they are allowed to handle it without
insulating gloves, so it is simply not possible for them to be
harmed by your generator unless *they are at fault*.


I do the same thing. (Ducks head as people scream at me.) And if I
didn't turn off the mains power wouldn't my generator be trying to
power up the entire neighborhood? What I'd really like is a little
light to come on and tell me when mains power is back on.

George , see my post above . There is a way to wire up lights so you'll
know when the power is back on - and have them usable to synch your genset
to the line so you can make the switch back to "shore power" without
interrupting your wife on her computer while she's surfing for new
(snow)shoes .
