UF 6/3 cable

[btk]

Plan on installing a sub panel in detached garage (50 amp) by burying UF 6/3 cable. In the areas inside my home and garage can I pull this cable through studs/joists or does it need to be in conduit. I can install it in a way that will not be subject to "physical damage"

Also, part of the underground run will be under a concrete sidewalk .. how far underground does the cable need to be?

Thanks.

Yes, you can run it through joists and studs. Under a sidewalk used for single family dwelling use only 18" if in an trench not covered by anything but good ole dirt 24 ". You will discover that #6 UF is a bear to work with, it will try your patience for sure. I much prefer PVC conduit installations using thhn/thwn individual wires. If your on a budget though they do make direct burial cable that is nearly identical to round NM-B cable that has jacketed #6 awg stranded copper thhn/thwn wires listed for direct burial. It beats the heck out of uf cable.

Hope your not related to that guy out here in my home state that went by "BTK"

That's the first thing I thought when I first saw this thread. I had to read it to figure out how "Bind, Torture, Kill" related to wiring.

Looks like I better change my initials!

Thanks for the input. I'm going to look for that round cable. Wasn't looking forward to working with the wide, flat stuff.

You wont find it at the home centers, you need to go to a local electrical supply.

The 'round stuff' is called type TC cable or "tray cable".
