Another Surge Protector Post

Whenever I pull into a RV space, the first thing I do before plugging my travel trailer into the power pedistal is I plug a yellow device into the 30 amp outlet (using adaptor) to check for polarity / open / gound issues... when all reads well, I plug my trailer into the 30 amp receptical... I am looking at a 2000+ Joules surge protector from CW... No over / under voltage protection but I seldom if ever use my Air Conditioner.. Only use a TV / Satellite receiver / refrigerator / power converter panel when plugged in. Is the over / under voltage protection / time delay feature offered by the more expensive Progressive Industries EMS system really needed when my uses are minimal and just looking for surge protection? Comments??

    Hi,

    103 is too low for the cut off. At that level damage is accumulating in the electric motor(s) of the air conditioner.

    Are you sure it is 2 minutes? I thought it was 3. 2 is not quite enough for the head pressure to bleed off.

    My own comfort zone is 108 volts.
