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.
