MC cable for direct burial

In doing some research, I found that there is a PVC coated MC type cable that can be used in direct burial applications. Could this be used instead of PVC and THHN between a main panel and a sub panel? Seems like this would be a lot easier to install. I just wonder if its available in a 1/0-1/0-1/0-8 configuration.

yes they do

yup

Aluminum MC Cable with PVC Jacket - Direct Burial Underground Cable

i would think no matter what it would be a special order, and you still have to bury it at same depth as pvc

so for what it's worth, it's easy to run pvc pipe one the trench is dug to depth
and i rather have the option to upsize the conduit now and pull the feed you need now and if i later decide to pull bigger wire, i can.

I agree with Mike, They make it but it likely costs an arm and leg. PVC conduit it rather easy to run and is widely available.

It's definitely a special order item, might even take 4 or 5 days for a distributor to get it. Be sure you order your connectors at the same time, they are special for that type of MC cable and are pricey. I would recommend sch 40 PVC and THHN/THWN conductors for a subpanel feeder underground though.

Just stay with PVC conduit it is far much cheaper and easier to find the parts you need the PVC coated MC cable is very expnesive and need at least amost a week ditto with fittings.

{ there are few spots I will use it but not really widespread }

Merci.

I checked with my supply house about it once, and they said they would order it but I had to buy the whole 1000' spool -- no thanks.

No thanks is right. It's PVC and THHN for me.
