I'm planning on installing aluminum feeders to a control center for a corn stacker, but having trouble finding any 2/0-2/0-2/0-1 quadplex that is aa-8000 alloy.

heres the manufactures specs of a few companies i'm looking at. otherwise supply house said they have some 2/0-2/0-1 triplex aa 8000 and a single 2/0 conductor they could sell me.
 
Maybe I’m overthinking this…

I believe so.
No conduit?

It’s a feed for a 100a disconnect, underground raceway will be 2inch sched 40/80 pvc. 100a disconnect is fed from a 100a cb inside a 250a 480v service. Should I just run copper? I know it’s more expensive but I have #1 cu and I believe it’s good for 120a… don’t have chart next to me
 
1/0 is the largest it will except, breaker will take up to 2/0. I was going to set an enclosure use Polaris insulated taps and go from 2/0 aluminum to 1awg copper…

Why bother with a cable assembly? Just pull individual THWN or XHHW AL conductors.

I guess it doesn’t have to be just thought that would be the easiest, but I couldn’t find any quadplex aluminum made of aa-8000. besides the mobilehome feeder which is only 2.77/ft ThTs kinda the way I was leaning single conductors, but I was thinking #1 cu until I saw the price… what’s the main difference even between xhhw-2 vs use-2? Price and the face use can be direct burried? Thanks again for all the help I really appreciate it!

1. Often cheaper
2. Convenient to have all the conductors pre plexed.
3. Greatly reduced chance of jamming/ can use a pipe size where jamming would be a deal breaker for non-plexed conductors.

Of course I pull individual conductors too, but I also use these plexed conductor assemblies frequently too.

These cable assemblies are what I have normally seen/used. I’m almost positive most the feeders/ aluminum at our plants is prysmian cable assembly, and it’s made of 1350…. I never knew there was a difference on alloy used, until the other day. The only plexed cable assembly that I can find online that is aa-8000 is the mobile home feeder…. Supply house said they could get me a roll of quadplex made of aa-8000, but I’d have to buy 1000ft and I only need about 180’…. Might be easiest to just get the tri pled and add a single conductor…

Just be careful that these are marked RHH-2. Around here the supply house sells some that is ONLY marked USE-2 and thus not accept indoors.
 
My situation is all outside, but good to know for future applications. So as long as it has the rhh-2 and use-2 it’s rated to be direct hurried and used inside. Is that have something to do with smoke and insulation properties? So the supply house told me they have a triplex use-2. 2/0,2/0,1. And can send out a single use-2 2/0conductor does that seem the way to go or should I see if they have some xhhw single conductor aluminum?

I think it has to do with flame retardant properties.

Jamming could be an issue with a bundle of plexed conductors and then another single conductor, but if there is plenty of room it should be fine

I’ve got enough pvc from 2-3 inch I should be able to find something to fit it in… since it’s use-2 I could direct bury it and then only sleeve the ends. Since I’m doing this job alone I’ll pry end up putting the pipe on the wire then the setting it down in the ditch… thank you for your input.
 
I should be fine to use the mobile home feeder right too? It’s made of aa-8000 aluminum, type xhhw-2. Xlp insulation, ul 44 types rhh& rhw-2. Ul 854 for type use-2. See the specs.l in second picture above There is a price difference of.33/ft betweeen the mobile home feeder “2.77/ft” and the supply house triplex+ single conductor. “2.34/ft” I’m not making any more or less money and seems like 59 dollar difference would save me a little work at least
