Surge Suppressor?

[dtontarski]

Is the gray device on the top of this panel some type of surge suppressor. How should this be correctly wired? This is on a Cutler Hammer Panel installed in 1976.

Hi,

I'm not sure of the exact terminology but it's some kind of lightning arrestor, which, in essence, is a surge protector.

OT - OF!!!

Thanks Mike. Is it o.k. to double tap it onto the main breaker terminals like this?

[hausdok]

Yeah,

I think so. I don't think I've ever seen one, but the question has been asked a lot here, on the ASHI forum, on Inspection News and on the NAHI and NACHI forums, and I think the answer has always been that it's okay.

If I'm wrong, Jim Katen or someone from a more lightning-prone area will chime in and correct me.

ONE TEAM - ONE FIGHT!!!

I call it out as being wired improperly.
