I recently wall mounted our bedroom TV. Naturally, that left both the AC cord and data cable hanging down the wall. That was totally unacceptable so I put a new box up high behind the TV, put the satellite receiver there too.
In order to provide AC to the new box I daisy chained off the duplex outlet in the old box. That box was single gang - new one is double, AC and data - and a shallow one at that. The old box already had two lines going into it and my new one made three. That means three 12 gauge lines...six individual wires plus a pig tailed wire nut for the additional three ground wires. I'm telling you, I had a heck of a time getting all that stuffed back into the box.
My question is, is there a right way to get all that into the box? Some methodology of arranging the wires maybe? I always hate using brute force, worrying about shoving a ground into something hot or maybe breaking the grounds' wire nut.
Yes, I could have replaced the old box with a new, deeper one but I didn't have one handy and didn't want to make a 20 mile round trip to get one. Even if I had one it would have been a pain...cut off the nail holding the old box, hope there was enough slack in the feeds to get into the new box, hope the hold-in tabs on the new box don't fall off. before getting them tightened...like that.
