I have a EMS-PT50X surge protector, and it seems like it has a problem. When I plug it into any source (15A, 30A or 50A) from a campground or from my home it takes a long time to gate power through th...

When you loose power it is important that you not re-start the air conditioners (IF that is they are running) for 3 mintues.. Most everything else in the RV (Except a compressor driven fridge) can re-start quickly but COMPRESSORS need 3 minutes of OFF time before they re-start.
I've seen many "Blinks" (Power failures lasting just a second or 3) and my Surge Guard holds off for 172 Seconds (Just shy of 3 minutes) so the A/C re-starts normally without damage.
If your EMS is truly a "Surge Guard" then it's a TRC product, not a Progressive Industries product as is the OP's, and your time delay is in fact an even shorter 128", not "just shy of 3 minutes". As I understand it the TRC Surge Guard also has a preset trip time of 8" - 10" before that 128" time delay is executed, the purpose of which I believe is to avoid nuisance power disconnects when there's a brief power disruption lasting less than 8" or when incoming source voltage is hovering right around the low voltage trip threshold of 102 vac. The Progressive EMS trips the instant it's low voltage threshold of 104 vac is detected.
