I'll try to explain. I currently have a whole house surge protector (BR Surge) from Cutler-Hammer installed in our main breaker panel. It takes the space of a double pole breaker.
Some time ago, I bought the CHSP Ultra as an upgrade to the BR Surge since the CHSP Ultra can handle a greater surge, has a lifetime unit warranty, and a protected equipment warranty. I never installed it.
Right now, our range (and house) is protected by the BR Surge. We also have a 110 volt plug in surge protector on our (gas) range. My question doesn't really involve the range (mentioned in another thread.)
Here is my non-technical explanation (others can clarify my explanation) - a Service Entrance Rated ATS (automatic transfer switch) has utility power going directly into it as well as the generator feed. The transfer switch sends either utility or generator power to the main distribution panel (loadcenter) which powers all of the circuit breakers (in the house.) The distribution panel is currently our main breaker panel, but our main breaker panel will become a sub-panel of the Service Rated ATS once our wiring is done.
The BR Surge (or the CHSP Ultra if) connected to the distribution panel will only protect the circuits after it, not before it, so the Service Entrance Rated ATS is unprotected from utility surges. One way around this is to properly connect surge equipment to the meter (before the ATS.) I would need to purchase different surge equipment to do this.
I was just wondering if I could protect the ATS, and possibly the generator, from utility surges with the CHSP Ultra that I have.
I'm not sure if doing this will cause a problem or not. Apparently, this is not a problem for a Cutler-Hammer ATS. Also, I don't know if doing this would effect the Generac warranty or not.
