Are the Alpha surge protectors different than the arc plugs in the Delta-4 switches? I've never had an issue with those at high power. Are they designed to operate at a low impedance (50 ohms) which would present a much lower voltage peak? Or could the arc plug in them become damaged and cause them to arc at a much lower voltage?

Appreciate the feedback. I'm certainly not impressed by having one marked HP that is clearly not. See my earlier post: the surge protector was my problem all along. It's arcing at about 300W. Do you have a suggestion for alternatives? I live in the lightning capital of the world ;) Lightning mitigation is not optional here.
