    Aluminum Ground Wire

    Is solid bare aluminum grounding wire hard to come by? I have called several (5) local electric supply distributors and none of them seem to stock any.

    The reason I ask is because I have a solar application with an annodized aluminum structure, and aesthetics are a primary concern. A green insulated equipment grounding conductor would look terrible so I'm trying my best to avoid it.

    Can anyone point me in the right direction?

    Thanks.

    Never bought Al ground wire. Never asked for it. Don't know how common it is.

    If you can't find any, tinned copper would give you that silvery sheen you seek.
    If you don't think too good, don't think too much.

    Like the others mentioned, I'd use tinned copper too.

    Googled - found Belden offers #8 sol aluminum.

    I remember installing some back in the early 80's for 'grounding' roof top TV antennas.
    Just because you can, doesn't mean you should.

    I wonder if you can paint the bare copper with a chrome paint?
    They say I shot a man named Gray and took his wife to Italy
    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

    I am not sure where you plan on running/terminating this but keep 250.64(A)&(B) in mind.

    + Another vote for tinned copper, for many reasons.

    Run it in aluminum RMC is also a possibility.

    The NEC doesn't mention that tinned copper may be used as an equipment grounding conductor. Has anyone found otherwise? (section 250.118 NEC 2011)

    WIMaster- The section you mentioned would be in regard to a grounding electrode conductor. The application would be for an equipment grounding conductor (connecting all of the panels and metal framework together, and then bonding it to a GEC in the foundation, but I would specify that it had to be 18in from the concrete at the termination point).

    I use to see a lot of it durring the housing boom. It was used to bond to the water pipes.
