Re: Plate Shields for house wiring
It is 1.25"
Take a look at 300.4(A), 300.4(B), 300.4(D), 300.4(E).
If the requirement was 1.5" that would only let us drill a 1/2" hole in a standard 3.5" stud.
A 1/2" hole would be worthless for power wiring.
With the 1.25" requirement we can drill a 1" hole dead center in a standard stud actually allowing some power wiring to pass through.
