tsumner Posted November 16, 2001 Share Posted November 16, 2001 I am running more power out to my garage. The electrical guy at work suggested I use the following wire, #8 thnn run thru 1inch conduit buryed 18 inches deep. Niether home depot or menards had it in stock.Menards recomended 8-3 nmb (with ground). Will this work ?Is there a better way to go? I will use a 50 amp double breaker at the main in the house.

DavyZ Posted November 16, 2001 Share Posted November 16, 2001 My brother and I are using 10-3 for a 30 amp dryer circuit, so...I think that their recommendation may be good. I'm not an electrician, but the 8-3 is beefier than a 10-3, yes? If so, it sounds right by the rule of thumb (educated guess). Davy Quote Link to comment Share on other sites More sharing options...
pparaska Posted November 16, 2001 Share Posted November 16, 2001 8 gage sounds right for 50 amp service. Check this out: http://www.ibiblio.org/obp/electricCircuits/Ref/REF_3.html I'd run the conduit and single wire 8 gage pieces in it. I'd hate to dig into romex with that much current capability at a later date! Quote Link to comment Share on other sites More sharing options...

Guest scca Posted November 16, 2001 Share Posted November 16, 2001 i think i ran 8/3 as well, not in conduit but in the underground cable - thick black crap. and a 50 amp circuit on the house. i buried mine 3' under- and then 12" of dirt over it and then a wide yellow marker tape 4" wide above it so if you dig you find the tape first. at least thats the theory.. btw: thats to code here...... works very well. i have a full breaker box in the shop - i did all my own wiring there as well. 30amp to compressor 220v 30amp to welder 220v and a sh*tload of outlets, 3' off the ground every 8 feet along all the walls. at least i dont have to go looking for power..or bend over overhead outlets for dropdown trouble lites and stuff. outlets are so cheap you cant have too many. just wire them in on triple wire (ala a kitchen) so they alternate on the circuits. max. 8 per breaker or ??
