I have read others and the bare grounding conductor being underground makes sense to me.
Question is is the insulation XLPE or XHHW and if it is XHHW could you strip the jacket and pull an insulated copper grounding conductor of THWN in a raceway underground and it all be NEC complaint?
Thanks
Just to claify this is existing and would re pull the insulated conductors from the SER and add the copper insul. grounding conductor to A,B phase and the grounded conductor.
 
Technically that is not compliant based on 300.3(B). Also the manufacturer instruction say not to install ser underground even if in a conduit. So you have 110.3(B) to contend with.

IMO, do it right because the whole thing is not right
 
Not trying to pull it in, going to pull it out and take the jacket off, pull in the individual conductors if they are XHHW insul. Would that make it legal if they are XHHW and does someone know for sure if they are XHHW or XLPE?

Thanks

From just a strict install viewpoint, you are going to have a booger of a time pulling jacketed cable in an underground conduit.

I will disagree with that, I have installed a fair amount of SER in PVC and it is not bad.

Never tried using an LB but sweeps are easy.

If they were individually marked as XHHW it would be code compliant.

Other than that you are out of luck
 
I use "mobile home feeder" URD cable now, it's ready to go. Not sure why you would want to waste time stripping SER cable, AL cable is dirt cheap as it is. Just buy the right stuff and be done with it.
