Subpanel feedline question

Jul 01, 2004 2 Replies

I am installing a subpanel in my woodshop. I need at the minimum a 30 A circuit. The run from subpanel to shop is less than 50 feet so voltage drop is well within tolerance.



I was thinking of pulling either 6 or 8 gauge cable and I have two questions:



1) Would you use 6 or 8 gauge or stick with 10 gauge?
2) Is 6 or 8 gauge a pain in the butt to work with at the main panel?

Also, any war stories on your panel installs would be appreciated.

What size is your conduit? If you have room for 6 or 8, I'd highly recommend it. 30 amps isn't very much for a garage, especially if you plan to run machinery out there. 6 and 8 gauge aren't hard to work with, assuming you have a decent conduit run without a lot of radical bends.

#6

only slightly more than the smaller gauge

Often I hear of additional capacity being needed once electricity is there. So I'd suggest #6 or even #4 and going with a 60 amp subpanel (a common size anyway). If the subpanel has a 60 amp (or less) main breaker of its own, then you can feed the #4 with 70 amp (or maybe more if the wire is rated for a higher temperature ... see NEC wire tables). If the subpanel is "main logs only" then feed it with a 60 amp breaker in the main box.
