Was URD ever allowed to a main breaker?

[WD40]

Hello group I replaced a loadcenter that had a bad main breaker with a larger one at a townhome in a 55 and over complex and the inspector approved my job but commented the feeder from the meter is in violation, it is 4/0 URD / XLPE from a gang of meter mains out at a parking area.
He mentioned another EC had also replaced a panel recently in the complex and there appears to a ongoing issue.
The customer was present for this conversation and happens to be on the board of the home owners association.
So we opened up the meter packs and all the units were wired the same with URD the codo's are not very old, perhaps 20 years old max.
The inspector says this is a construction defect and URD was never allowed by code to enter a building, and has a inferior alloy, what do you all think?
My job is approved, done and paid, the inspector is not mandating a fix. I want to get some feedback to the customer per his request.
I was able to find the data sheet for the URD cable used: link.

URD with no additional rating such as RHW is not an approved NEC wiring method

It is both the alloy, as that uses utility grade aluminum and not the 8800 series alloy required for use under the NEC, but is and the fact that it does not have the fire and smoke ratings required for interior wiring.

Thanks for the responses, the data sheet says the conductors are:
Class B or SIW compressed 1350-H19 aluminum.

 

[don_resqcapt19]

1350-H19 aluminum.

That is utility grade and not the alloy that has been required by the NEC since the mid 70s.

Not completely true. USE-2 is allowed to be 1350 alloy. Granted it would still be an issue for the OP as he would need the RHH rating for use inside.

Not completely true. USE-2 is allowed to be 1350 alloy. Granted it would still be an issue for the OP as he would need the RHH rating for use inside.

That does not appear to be the case for dual rated USE.
From the UL Guide Information for Service-entrance Cable (TYLZ:

Single-rated Type USE or USE-2 cable containing other than solid 12, 10 or 8 AWG conductors are of an EC-1350 grade aluminum alloy or a registered AA-8000 series electrical-conductor-grade aluminum alloy. In all other cables, the aluminum conductors are of a registered AA-8000 electrical-conductor-grade alloy only.{

That tells me that all dual rated USE must use the AA-8000 series alloy.

Yes but, I think the in the beginning this thread was about some URD that is not even rated as USE.
