Power inlet installation question

bigyellowJanuary 19, 2012

Hey guys. I finally got my 10 circuit transfer switch that I ordered on November 1st, 2011! I waited until everyone went to sleep and installed it two nights ago. It went pretty smoothly and took me about 2.5 hours to do.

I've finally decided on the location of the power inlet box and want to install that in the next few days. So here's my question. I was planning on using the knockout on the back of the power inlet box and mounting it on the siding of my house. I'll drill a hole through the siding, through the rim joist and to my transfer switch. How do you clamp the 10 gauge wire in this situation? Or, do you?

If I'm using a knockout on the side or the bottom of the power inlet box, its simple. I use a standard wire clamp. Are there wire clamps specifically designed if you're using a back knockout? Thanks in advance.

You make the hole large enough to clear the cable clamp.

Hey, brickeyee, thanks for the response. Yeah, I thought about that. Is that what's normally done? If so, I guess I can do that as well.

"Is that what's normally done?"

The cable clamp is required.
If you use conduit you can connect directly to an interior box, but if you are using cable the clamp is required.
