I know the best kind are the ones which would be wired into the system, but saw this today and wondered if it would be any good. Is this a "better than nothing" or "you get what you pay for" situation...
For anyone that is not sure of the difference between a SmartSurgeProtector(SSP) and an ElectricalManagementSystem(EMS), here is a chart of ProgressiveIndustries models with their capabilities. The EMS will interrupt power on low/high voltage, and when other various faults happen. The SSP will provide surge protection, but will not interrupt power on the various faults. Only detect them. You know, like the security monitor in the tv commercial.
