Conduit placement in walls

crosscountry's picture

I am wiring a small addition on my own home near Chicago. Conduit required by local permit office. If I position a handy box correctly for 1/2 drywall, it seems like it puts the knockout at the edge of the 2x4 wall, meaning if I run my conduit from the from the crawlspace the conduit, to the box, and then up the wall I will also be at the edge of the bottom and top plates. I guess its ok, but my OCD make me think it would be better if it was farther from the edge...but then I'd need offset connectors and not a straight pull. Whats the best/common practice?

Put a kickout in the conduit (offset) or use deep plaster rings on a reg. box.

Plaster rings (post #216591, reply #2 of 4)

Use 4 square boxes with plaster rings in a thickness to match your wall finish. Electrical supplies have more choices than box stores. An added benefit is the extra room in the boxes. They can be had with brackets.

Thanks Calvin and MGMahan. Sometimes its easy to overlook the simple solutions. While both suggestions would work, I ended up with 4" boxes and rings to solve the placement but also to make linking boxes in series much easier.

Handy boxes are never used in commercial work. Always 4 square.
