I have a 220v GFI breaker/disconnect box on the side of my house near my Jacuzzi. (Culter-Hammer (Eaton) BR24L70RP type 3R). The box contains a neutral bar and assembly for connecting a single breaker, plus an door for accessing the breaker handle as a disconnect along with the test/reset buttons.
I have obtained a small (<1 cubic inch) insulated package containing 3 MOVs with attached wires that functions as a 220v surge suppressor. The ground lead can go to an open position on the ground bar. The other two leads need to attach to the 220 red and black leads, respectively.
All wires are stranded copper. The connector style completely enclose the wire. If you place a surge protector lead together with a 220 feed wire, you can not tell which strand belongs to the 220v wire and which strand belongs to the suppressor as you insert them into the connector.
My question: May I legally place both wires together inside a lug connector?
In the opinion of a couple friends who are engineers of the electrical and mechanical flavors, there is nothing obviously wrong with doing so. The connector surrounds all strands and compresses them together.
But, I know there is a prohibition against connecting wires to each other inside a breaker box, e.g. extending a wire to reach a breaker. And, the code has strange requirements not always traceable to measurements or calculations...

If this is a no-go by code, how would one proceed?
In a larger breaker box, one puts in another breaker and connects to it. But that won't work in this 1 slot disconnect box.
Also, for the surge suppressor have time to work, it must be attached across the three 220 wires upstream of the GFI.
