I have 125' Aluminum wire that I want to use add a sub panel to a post or RV. The RV requires a 30amp outlet. Also, I want to add a yard/security light to the subpanel.

The wire I have is (MT 2 AWG AL XLP 600v 2004)
I got it from Excel when they borrowed my power to feed the neighbor when they were down.

Couple questions:

Does this go into a junction box where I splint into copper wire to run to main box?
Can this wire be buried in 2" conduit for the 125' from cabin(main box) to sub box?
Is the sub panel necessary, or can I use a outdoor box with a breaker?

Any ideas?

Thanks,

Joe

Sorry for the delayed response.

I just did a quick look at the NEC 2008 Code book and was able to find cable type "MTW", which is defined as a Machine Tool wiring in wet locations (60C) or in dry locations (90C). Table 310.13 <Moisture, Heat and oil resistant> wire.

I cannot determine if this is a cable or single conductor wire. Also I cannot find cable type "MT".

So here are some questions for you:

What will the be the load calculation for the sub panel?

Did do know that a sub-panel feeder is required to be four conductors?

Are you planning for a service drop (overhead feed) or a service lateral (Underground feed) to this sub-panel?

Can you provide a picture of the cable for me, please?

XLP is a direct buried type of insulation.

The cable is probably four wire, and is called URD.

Splicing will need to be in a junction box or a buried hand hole.

4 Wire #2 URD cable will do better in 3 in PVC, esp if there are sweeps/elbows, that distance, but 2 In with no ells will work.

If you only need two circuits, a 2 circuit panel rated NEMA 3 R , Raintite, will work.
