No ground

This was originally posted on APC forums on 2/20/2011


The outlets in my house have no ground (the ground prong in the wall outlet is not connected to anything inside the wall).
Will an APC surge protector protect against a surge, or does it MUST have a ground connection?

Thanks.

You could use surge device(s) hardwired into the breaker panel. Still needs a ground in the panel, but will work even if the individual circuits are not grounded. Note that there is a difference between a surge arrester and a surge protector - carefully read the specs to see what a specific item will or won't protect against. If I understand correctly, having both an arrester and suppressor is the safest option (if this is incorrect I'd appreciate a correction - the information out there isn't very consumer-friendly).

Thank you for the answer.

That's a bummer.
Is there a surge protector that can operate without ground, for home use?

Thanks.

I would imagine any surge supressor that actually works requires a ground.
