surge protection device - double wire under lug?

[PoorOwner]

This was recommended to add to the air conditioner circuit to protect the circuit board etc.

OK, simple enough, I plan to put it in the disconnect box . but to install one, I don't want to put 2 wires under the terminal. Seems to me that's a code violation.

But what if this device doesn't draw current? it is not exactly like tapping another circuit into a breaker.

I believe it goes on it's own separate breaker.

If im gonna go to all the trouble and cost for one of those, i would rather have it on my main service panel.

I called the company and they told me I could wire nut it...

Only listed to work in Eaton BR panels.

There are other Eaton models that have classifications for use in other brands of panels.

Wyliesdiesels - thank you for the Eaton link!. I have a CH 200A panel and the link you gave shows two types that would work for me. One takes two spaces and provides only surge protection. The other is the same yet can be had in 30A or 50A breaker format as well so as to not lose those spaces for power devices. The surge-breaker combo is pretty clever.
