OK I have a bathroom with wall to wall very hard and thick porcelain tiles. The existing light switch was mounted on a 4X4 metal box with a 1 gang 1 device mud ring - I wanted to add an exhaust fan and a GFCI receptacle...so I carefully measured the size of a 4X4 metal box - took out my angle grinder and a diamond blade and cut a larger hole, so far so good. The original box was set deep so I was able to slide in a 1.5" extension ring, and did all the wiring for the ceiling light, exhaust fan, receptacle etc...everything ready to go. The front of the extension ring is still about 1/4" recessed from the finished tile, so I went to get a 1/4" raised two device metal mug ring. When it comes time to put the mud ring on :eek: HELLO...the mud ring is a bit wider then the actual box! :madhell: not much, but about 1/8" or so? But just so that I cannot fit the mud ring on to the box! It won't fit. I tried different ways and I can't "finesse" it in.

So what are my options now? I am contemplating a few possibilities. (1) Get a two device plastic mud ring, may be Carlon makes a blue one, and use a grinder to shave an 1/8" off the edges to make it fit. (2) Get a flat two device mud ring and mount it over the finished tile, and use longer screws to attach it to the box. Thanks in advance for any comment.

I'd like to add a 30A 120v RV circuit to my panel and I'd like to know if I can do it on my current panel. [ATTACH]50226[/ATTACH] [ATTACH]50227[/ATTACH] [ATTACH]50228[/ATTACH] I'd add the circuit to one of the extra spaces at the top right of the panel. I'd use #8/2 wire and the run is about 40'.
