Use-2

[sberry]

I am having a brain seizure, is USE-2 legal inside?

 

[pattenp]

Nope, not as a lone rating.

 

[Dagny]

not flame retardant.

 

[Dagny]

There is an 8000 series that is.

??? Really, can you provide more info. I know there is 8000 series aluminum but that has nothing to do with the insulation rating being fire resistant. Besides, NEC 338 doesn't allow USE/USE-2 inside.

 

[Dagny]

it will have several other insulation ratings on it 8000 may just be what they call it at my supply house. I have also heard it called mobile home feeder.

 

[sberry]

I think that is the only rating.

Mobile Home Feeder (MHF) is an assembly of RHW/RHW-2/USE-2 conductors. 8000 series is just the type of aluminum alloy and is not the identifier of the conductor use rating.

The terms probably differ by region. Personally I hadn't heard the term mobile home feeder before this site. I have always just asked for triple rated URD if that's what I want. Stabiloy is also a common term around here when talking about triple rated 8000 series direct bury wire.

I’ve never seen USE-2 that wasn’t rated RHH and RHW-2 as well. Maybe back in the day it was a thing?

I will look again. I thought all I saw was USE. The rating would be grouped as I recall.

What I usually get from PLATT looks like this.

[pattenp]

Typically UD or URD cable carries only a USE-2 rating.
