Actually, this isn't in a wall but rather in a long metal "power strip"... the kind where you have 9 single outlets in a row (but no surge protector). I want each bank of three outlets to be switched separately so I opened the back, added two hot lines as described in the diagram, and ran these lines back to the opening on the end where they all combine in a 20 cubic inch single gang box with a 3x switch in it.
That should still be ok, right?
