Sorry I didn't see Dave had already answered your post. I'll leave it up as I already typed it
The SSP 50 according to their web site does a nice job of a pedestal check when plugging in. However the protection stops there. Except for line surges. SSP-50
The EMS units continue to protect after the "plug in" and beyond damaging surges. Low power in an RV park is one of the most damaging causes of roof top A/C and other appliances failures. Low power comes from a full RV park and everybody using their A/C's etc. at the same time causing the power to drop below the safe 104 voltage. The EMS will shut you down before damage can occur to your appliances where a surge protector will not. As power comes back to a safe level the EMS will allow power back to your coach with out you having to reset anything. That is one of the major protections of an EMS unit.
Also the SSP 50 protects for surge rates of 1650 Joules and 45,000 amps where the EMS units protect at 3580 Joules and 88,000 amps. Almost twice as much protection for lighting strikes.
