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.
