can I use Triplex or quadruplex to run over head from distribution panel to run as feeder to a temp building.

As long as you purchase the right Quadruplex cable. The overhead triplex or quadruplex will have the internal supporting neutral component [AAC. ACSR or AAAC] while the underground triplex or quadruplex will not. So its always important to know which you are buying...Yes, it is made for that.:thumbsup:
However...many of the Triplex and Quadruplex are tripled rated with an insulation type shown in 310.104. Just depends on the manufacturer i guess.Many code authorities do not accept tri or quadplex cables as they are not listed and not of one of the insulation types shown in 310.104. Check with your AHJ before installing it.
While I have seen that for conductors intended for underground installations, I have never seen that for conductors intended for overhead installations, and that is the subject of this thread.However...many of the Triplex and Quadruplex are tripled rated with an insulation type shown in 310.104. Just depends on the manufacturer i guess.

Honestly, don't question it.
(a) works for the utility& (b) it's outside and causes little concern.
I could link you to the catalog items...However, Don has spoken and far be it for me to thread drift.:slaphead:Can you link to some for overhead use?
What I see here is only marked XLPE and no listing.
Does the catalog link show listed overhead conductors or listed underground conductors? I am sure most of us would be interested in a link that shows listed overhead triplex conductors.I could link you to the catalog items...However, Don has spoken and far be it for me to thread drift.:slaphead:

I think that what we are talking about when we are saying overhead triplex or quadplex is what is also called "service drop" cable.
In order for a conductor to be recognized as suitable for use by NEC it must be a type that is mentioned in 310.104. XLPE is not mentioned in 310.104. XHH, XHHW, XHHW-2 are all XLPE variations that are mentioned in 310.104, but without additional designation just XLPE only is not a conductor recognized by NEC. I have never seen an overhead multiplex cable similar in construction to what POCO's use for service drops that has any such designations mentioned in 310.104, but will not claim there are none either. You do run into similar conductor markings on underground multiplexed cables. If it says XLPE only it is not recognized as acceptable by NEC. If it is identified as USE and nothing else - it is recognized by NEC but is restricted from being used indoors.Well I have to apologize as it appears I misunderstood the question.
My original statement was simply to explain that their are two different types of overhead Triplex and Quadruplex cables out there on the market. I know this because we make both.
We have a Triplex and Quadruplex Underground Distribution Cable and we make Triplex and Quadruplex Overhead Cable which is primarily used for Service Drops, but not limited to that application only.
The underground Tri and Quad is tripled rated in that it is USE-2,RHH and RHW-2 rated for use in direct bury or within a raceway as well as within the building structure. Due to it's triple rating it can serve multiple functions. However, if it was simply USE-2 then I would be limited, this is why it is thus triple rated and evaluated for such.
The overhead conductors in the Tri and Quad, at least the insulated ones are XLPE insulation and would easily meet the same permitted qualifications of UL-44 as Thermoset. The hickup is that the supporting grounded/neutral conductor is uninsulated so it would not be permitted within the structure...and from the original question I did not gather it was an interior application...but I could be wrong as I don't want to read the mind of the OP. I have enough trouble with the voices in my own mind:angel:
My point was to just make the OP aware that their are multiple types of Tri- and Quad and to not blindly accept what a supply house may give them when they as for a Tri or a Quad...nothing more.
Again if I misspoke or represented it incorrectly to the OP I apologize as I was just bringing my experience with the product to the forefront.

BOTH of you obviously did not read my post.......and my clarification...or would you both rather just (yes you iwire) jump on me anyway?In order for a conductor to be recognized as suitable for use by NEC it must be a type that is mentioned in 310.104. XLPE is not mentioned in 310.104. XHH, XHHW, XHHW-2 are all XLPE variations that are mentioned in 310.104, but without additional designation just XLPE only is not a conductor recognized by NEC.

Places that can use these conductors are POCO's or others that do not have to comply with NEC.
