Under ground wiring on top of pvc water piping.


I built a house about 3 years ago and had a 40'x24 shop built at the same time. Since then I have had electrical problems with the wiring feeding the power box on the shop. The wiring was buried undergroud without being inside pvc piping. I found a section of wiring about 6 feet from the main house power panel that had corroded thecovering on the neutral line and one of the hot lines which put 110 volts ac on the neutral bar. I have just started digging it up and found that it was buried just above a pvc water line. my question is: Is this up to code? My contractor lost his business due to the back economy. If this isn't up to code can I go to the County inspectors office and file a complaint?

Corroded wires? Are you saying the insulation has rotted away or has something else damaged the wires? What size and what type of wire feeds the garage? Could the wire have been damaged during installation?

Depends what you're asking about.

As SP said, relating to the proximity to the water line, there's no code violation there.

Two other things that are not yet identified though are the type of cable used and the burial depth.

If it's NM-B it's a code violation (should be UF cable since it's not in conduit.) Burial depth for a UF cable supplying more than (1) GFCI-protected 120V 20A branch circuit would be 24" unless protected by a method listed in Table 300.5.

Sounds like it was damaged by something...

But what is the TYPE of cable? Is it SER (not allowed to be used underground)? It should be USE or URD, which it sounds like it is because you said the neutral was covered.

Six feet from the wall and 8 inches deep? Sounds like it might have been struck by a shovel, tent stake, birdfeeder post, etc.

Under ground wiring on top of pvc water piping.


It was only about 4-8 inches across my flower bed that was prepare by the contractor. It then cut across my yard at no more than a foot. The is no GFI breakers. It is a 70amp service feeding 2- 240amp outlets, 2- 20amp, and 2- 15 amp breakers. I hadn't dug at all in the flower bed or yard. I found the side of the dot wire had a 1/2" by 1" corroded spot on it and the neutral had been eaten almost in half with very little of the covering still intack. I was also talking about filing a code violation against the electrician that worked for the contractor

I just cleaned the dirt off of some of the cabling. it says Southwire (UL) AWG 2 AL TYPE USE-2 60 mills XLP insullation 600 volts sep/25/2005 #126950MCS.


Southwire Type RHH or RHW-2 or USE-2 conductors are used with conduit as specified
in the National Electrical Code
1

When used as Type USE-2, conductor is suitable for use as underground service entrance
cable for direct burial at conductor temperatures not to exceed 90C

When used as RHH, conductor temperatures shall not exceed 90C in dry locations

When used as RHW-2 or USE-2, conductor temperatures shall not exceed 90C in wet
or dry locations

Voltage rating for RHH or RHW-2 or USE-2 conductors is 600 volts

The cable is the proper type, but the burial depth is a violation.

Was this circuit inspected?

You're not going to get anywhere by complaining to the inspector's office at this point. Better to just dig it up and replace it.

The shop and house were both built at the same time. I would have expected both of them to be inspected. I have about 30' left to finish digging up, and will be replacing it next weekend in pvc style pipe for protect from weather and the water line.

What type of PVC should I use to run my underground wire in? White, Gray, Sch 40? I want to run it in conduit because of the corroded wires that I found after the initial installation. I never dug, buried or drove anything into the ground where the problen was found. It had to have happened when one of the other sub-contractors came in and did there thing prior to me moving in.

Electrical PVC conduit.
Sch40 is fine for underground. Anywhere above ground subject to damage should be Sch80.
