I am installing a meter base on a new house. The 4/0 cable from the meter base to the 200 amp service panel will exit out the back of the meter base, turn and go up for about a foot, and then enter into the back of the service panel. I am planning on putting a cable clamp on both the meter base and the service panel where the wire enters each box. Usually I have seen these cable clamps installed such that the clamping part is on the outside of the service panel or the meter base and the threaded part is on the inside, but I was wondering...is there really any harm in having the clamp part on the inside? It would make things much easier to install. I could install the clamps before mounting either box and then tighten on the cable from the inside of each box. I can't seem to find any code problem with this - I just haven't seen it done (but then again, I haven't seen that many)
Thanks for any responses
