another "what is this?"

[Chris Stichter]

Can someone please advise me on what is attached to the AC disconnect and it's function? Surge protection?

Thanks!

Chris

Surge protection?

Yep.

And multiple tapped too.

It appears to be a surge arrestor However you better check these wire terminations because double terminations are not allowed unless the terminal block is listed for this use.:)
