[RFI] Recommendation needed: Whole house surge protection

[Steve Kurtzman]

UL calls them Surge Protective Devices or SPDs (formerly TVSS).  Common
heavy duty commercial mfrs are Liebert, APD, APC, Eaton, Siemens, GE and
Square D but you probably don't want to spend that kind of money.  It's
like insurance.  How much is enough?

They are separated into Categories A, B and C with 'C' being the service
entrance panel and 'A' being the receptacle or power strip.   I've seen all
of the these submitted on (commercial) projects but have no recommendations.

RE previous posts:
A whole-house protector won't protect against direct lightning strikes or
sustained overvoltage caused by HV lines touching 120/240V lines
