I have to install a dryer outlet in a garage where it has unfinished
sheetrock. I purchased a surface mount outlet similiar to this one:
http://www.acehardwareoutlet.com/(x1...aspx?SKU=33287

It came with 2 half moon clamps for the wire, and the instructions say
for wall mounting, put the clamp on the bottom knockout. For floor
mounting, use the knockout on the back.

This would mean that I would have to come out of the sheetrock with
the wire, then turn up 90 deg to the outlet. Is this right? Is there
any reason why i cant use the rear knockout so I can come inside the
sheetrock and through the rear knockout?



No, but you should try and get one edge of the receptacle over a wood stud
so that you can mount it securely. The larger size outlets don't always
hold up well when they are only fastened to the drywall.

Another way to go is with a 4" x 2 1/8" square box with a surface cover and
dryer receptacle. This would enable you to get part of the box over the
stud and still have space to enter into the back.
