Can I use Aluminum Wire for the RV Electrical Service?

By Dave Rongey - Summary:

I have a RV that requires a 30amp service. The RV is approximately 125ft from the Electrical Circuit Breaker Panel.

Electrical Question from Joe about Electrical Wiring

Received from Joe a Handyman in Gordon, WI

Question: I have a RV that requires a 30amp service. The RV is approximately 125ft from the Breaker Panel.

Excel Energy had to bridge my neighbor’s power temporarily off my power, I asked them for the service wire before they left and they gave it to me. I believe it is aluminum.

I have a couple questions:

Can I use this wire to run out to the RV?
– I am going to have a receptacle
Can I splice copper wire to this?

We also want to have a yard light(post) out there too. Do I need to run a separate 15amp wire for this? or can I pigtail into the 30 amp run?

To run 8/2 Romex UF out there is pretty expensive, I have this service wire, but is it too big? especially working it into the single pole 30amp breaker? – or can I splice 8/2awg copper to the service wire before the service panel to make it easier to work with?

I really appreciate your professional help.

Thank you,
