Hey guy I'm a new electrician. I have picked up a builder that only builds garages most are detach from the house. So I have been running 2/2/2/4 URD cable to the garages from the existing panel or a combo panel. The last garage I just finished I failed it. Due to were the wire that came in from the out side of the garage was in 1 1/2 pvc to a lb into the garage. once I got into the garage I ran the wire up the wall less than 36" to the bottom of the panel. The codes official says it has to be in pvc all the to the panel. Can anyone help me on this? Is the codes official right. Is this a NEC code or a builder code?

Did the inspector cite the code violation?

Was it an issue with physical protection of the cable?

If these are individual conductors they need to be in a raceway.

If it's a cable assembly(SER for instance ) they don't.

This 2/2/2/4 has no outer jacket right?

It is four individual conductors?

I know you called it "URD" but that is not an NEC term, is it marked USE or RHW etc?
 
The 2/2/2/4 is a direct burial cable.

It does not have a jacket over the wire. It is four individual conductor.

He did not cite a code violation.

I understand URD is direct burial cable, but I need to know what kind it is to the NEC before I can look up the code sections.

Unless you are doing solar array work or cable tray work there is almost no time you can run individual circuit conductors exposed above ground.

Depending on the wire type you might not even be allowed to bring it inside the building at all.

So far it sounds like this

310.10 Uses Permitted. The conductors described in
310.104 shall be permitted for use in any of the wiring
methods covered in Chapter 3 and as specified in their
respective tables or as permitted elsewhere in this Code

You did not use a wiring method from chapter 3.
 
If the panel is recessed then you can pipe up on the outside then LB into the panel. If that is not acceptable then put a box on the exterior and splice SER cable up to the panel.

If the garage isn't going to be sheetrocked or finished then put back to bak LB's down low and then up to the panel

So the other garages were done the same way? Where they inspected? I would suggest you fix them all. There is no 2015 NEC code cycle per your profile.

Since July I have done about 15 to 20 for this company. Some of them are combo panel. The other ones are tied into existing system. This one was in a county that we hadn't wired a garage in.

Be on the lookout for URD that is not rated RHH-2 along with the USE-2 rating if you want to use it above ground. Also look for the "sunlight resistant" rating if you will be using it for a overhead service. The common alternative to a URD type of cable would be single conductor XHHW-2. As others have said, all of these need to be in a raceway above ground.

Thanks for responding to my question. All I know was the supply house always called it Urd cable. Now I understand the difference
