Surge suppressor: before or after the transfer switch

Hi,

It would be best to put it before the transfer switch.

The generator is a known power source and can be monitored for voltage when in use. It is unlikely that there would be a surge from the genny.

I see surging non-inverter generators in news trucks all the time at work (especially the older ones) and the generator man makes a pretty good living off them.

The delay in the surge guard is whatever you set it to: Instant or 2 min. I'm not that impatient.
