I use a Square D interlock kit on my 200A

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.

Even the cheaper ones are an awful lot of money for a small
sheet-metal stamping.
