Power Feed to Sub-Panel - Conduit Required?

[nwav8tor]

I'm going to add a new sub-panel (100A or less) in my attached garage. It'll be right next to the existing 200A panel. Both will be recess mounted into the drywall of the garage. The feed will exit the bottom of the main panel, go through a stud and enter the bottom of the new panel (total run exiting one panel to entering the other is around 3 feet). Does this feed need to be in conduit?

assuming you're running some type of cable rated to be run outside of counduit (such as SER, NM, etc), no conduit is required unless your AHJ requires it.

Honestly in this instance I would use EMT regardless, the cost is minimal and it protects the feeders.

I'll mention a couple things. Double check that your panel covers won't overlap with only one stud between them. Since you'll only have an 1.5" to work with use a rigid ****** between the panels. Drill an oversize hole in the stud big enough to fit locknuts on the ******. You want locknuts on both sides of each panel, 4 locknuts total. Don't forget your plastic bushings as well.

I never even thought of going from the side of one panel through the stud and into the side of the other panel using rigin ****** and locknuts. That would invovle actually unmounting the existing panel and I don't really want to do that. I think I'll just stick with going down from the old panel, horizontally thru the stud and up into the new panel.

There is no reason to mess w/ the main panel, feeding the panel from the lower kockouts of the existing panel is quick & easy.

You don't need to remove the main panel to do as Aceman suggest. You use a hole saw from the wall cavity of the new panel to cut the over sized hole. Just line up the saw with a knock out in the main. Make sure the hole saw pilot drill doesn't nick any wires.
