Electrical Help - ASAP!!!
Hi Hope you guys can help me.
Had a breaker trip recently. Upon investigating the cause, I've isolated the problem to the electrical line that feeds my shed. What I discovered is that the ground wire is "hot".
Here is how the line to the shed is set up:
Power to the shed is tapped at a GFIC outlet at the exterior of my patio. The line goes down the GFIC Box through conduit under my patio slab.
Note: when I had the patio slab poured I told my contractor about the plans for a future shed which I wanted to have power run to it. I told him the line would be tapped via the GFIC outlet. He then went ahead and put in grey conduit and ran 14/2 NM through the conduit. The conduit was laid on top of the area where the patio was going to be poured. All worked well for the past 6 years until now.
Please note that I think the contractor screwed up by not trenching and burying the conduit "underneath" the slab, but simply laid the conduit in the area where concrete would be poured and thus enveloping and imbedding the conduit within the slab. What I think has happened over time is that the patio has moved at the control joins and shifed and "snapped" the conduit and thus damanged the wiring. At least this is my thoughts.
My conclusion is that I have to "pull" the 14/2 NM and fish in new wiring or simply abandon and start over. Any ideas suggestions?
