Re. GFCI Circuit protection question-outdoor wiring
If you didn't already by the wire I would run it in conduit. And for
the GFCI question, you can buy GFCI breakers if your coming from the panel. |

Does your code book say anything about running two feeders to one structure?
Generally not a good idea for several reasons including more expensive. One adequate sized feeder and a sub-panel would be much preferable. If your heater is in an area with plumbing, concrete, dampness or other possible ground sources it should be protected by a GFCI breaker. Approved direct burial cable is available and some but not all codes permit its use without further protection. In the long run it is always best to follow your local codes and your inspectors advice. A non-conforming electrical installation has few advantages and can be a significant liability.

Looked online and at -some- stomres, although I havent had the opportunity to visit specialty stores. And if I dont need them, I dont want to use them, since they are VERY expensive for a dual 20A GFCI. As far as conduit goes, I have toyed with theidea, but everything else I have read, and everyone I have talked to, says it just isnt necessary. Even the book I have that is all about "above code" just says bury them 2ft insteat of 1ft. Conduit makes it a PITA more than it already is. |

Don Young Well I am not certain about local codes. I guess I better check. My goal was not to skirt code, but to follow it. as I said in the above psot: I suppose code could be different here (in seattle) but I dont really know. Guess I better check on it. I guess my choices are -keep it the same and not worry about it (what is the harm in having two circuits off the main panel? -change the heater to 120V, deal with smaller heating capacity, and use the two wires I have already started running (they are not underground) to one dual 20A circuit -change the wiring to 10/3 w/g and run a 30A subpanel, wasting the $44 I spent on 250ft of 12/2 w/g and the time under the house. However this is definately not a cheaper option than 12/2 with two circuits, even if I hadnt purchased the 12/2 already or I supppose I could run it as is, and change it ater if needed. I guess i should run conduit so I could pull 10/3 out if I need later dunno what's best |
