Most PIs have higher numbers.

Which is irrelevant if that protector does not have a low impedance connection to earth. Those numbers are relevant only if that current connects low impedance (ie at the pedestal) to what must absorb that energy.

Furthermore, a minimal parameter for that one type of surge is 50,000 amps.

Again, this anomaly is rare in campgrounds. Other anomalies are a greater concern. If this anomaly is a concern to an RV owner, then his protector must make a low impedance connection to earth by attaching at that pedestal.

I was comparing Apple's to Apple's for the HWC50 in discussion, not generalizing, but whatever.
