Whole House Surge Protector - Advice Needed
I am looking for a whole house surge protector that I can mount next to my circuit breaker panel. I have looked at the Leviton 51120, the 51110 and the 42120.
The 51120 has no neutral to ground or line to ground protection from what I can see.
The 51110 has only a 20mm MOV vs 40 mm for the 51120 and the 41120.
I have seen the 51110 for around $60; the 51120, about $200; and the 41120 for around $400.
Is ground protection needed? Is the 41120 overkill for a single home? Do I need to spend $400 for adequate protection?
It's very important to me to protect all my appliances and electronics. We experience too many power failures. Desperately need advice.
