S stevej Member Jul 20, 2006 #1 1) Is it legal to use the concrete cap on the PVC floor box to install MC cable, istead of the standard device cap? 2) Can you cover the 4" round hole in the Sales floor, slab with a sheet metal & then put a 4sq on it? I say "no" to both but need to prove it Last edited: Jul 20, 2006
