First let me tell you what im doing on this job. Lady called and said she has no lights in the garage, pond pump outlet doesn't work, and shed light doesn't work. She also said she felt a light shock touching the aluminum siding on the garage.
So i go in the garage its a complete nightmare! Romex everywhere, disconnects everywhere, receps all over the place, switches ect...
Most of it was done ofcorse by the home owner
Ok so here is what layout is in the garage... You have the 3 wire feeders coming underneath the driveway and up in the corner of the garage into a 50 amp Murray circuit breaker disconnect. The load goes across the garage feeding another 30 amp murray breaker disconnect that feeds a recep for a welder. Also off of the load it feeds an OLD name? fused disconnect next to it. When i opened the fused disconnect i seen lots of neutrals wire nutted together with the grounds. From this disconnect it feeds a **** load of receps and switches all over the garage. It also feeds a switch that controls the pond gfi it transitions to UF at the switch.
Now the pond and shed are like 10 feet away from the garage. The shed is aluminum and the garage has aluminum siding.
There is a brand new black top driveway that seperates the shed,garage, and pond from the front house about 15 feet away.
I plan on putting a new subpanel in the garage and eliminating all the old disconnects and starting from scratch. As far as bonding, grounding what are your thoughts?
p.s. phone line was run in the conduit(pvc) with the feeders. Not sure if i should do this like a new service bond the ground with neutral in the panel and drive a ground rod?
