    I Agree Gust.

    But more Importantly, ..... The "Strut" is Extremely Important, & BBeerme can fill you in about that.

    Keep in mind, since it was from the pole to the service panel, the utility company installed it.

    How your buddy got by with #8 Tri-plex baffles me BBeerme.
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.

    I use 56% silver on everything except steel.

    I understand, but, .... Per Annex B, Page 70-701, Table B.310.15B(2)(3) of the 2017 NEC

    #8 Copper's high rating is only 59 Amps at 194 degrees F., & if it's Al., then it's lower.

    In my "Humble Opinion" , ... The "Utility" Fubared the situation.

    I don't know the code, but I do know you need to find the table that rates wire size for open air conditions. If I'm not mistaken, my buddy did find that table, and was quite surprised how much current a wire can carry when it can freely dissipate the heat.

    What I quoted, unless I'm severely mistaken is for "Open Air", ... Can you get the Reference from your Buddy, for me, BBeerme?

    No, he's long gone. Retired to Hawaii, haven't heard from him since.

    Keep in mind, it was probably a real short run as well. And he never had a problem with it.

    Kinda makes you wonder if the wire was even insulated.

    I believe the utility company isn't bound by the NEC, and can (and do) run their conductors as hot as they care to.

    That being said, I am surprised #8 was chosen and even more surprised that a welder was run off of it. :Grin:

    I would fire everything in the house up and see what your incoming voltage is. If it is more than a 5% drop then call the utility. If it is less than 5v then i wouldnt worry about it.

    I Agree Shell,... And that is a very "Grey Area" where the Contractor is required to follow the NEC, ... The "Utilities" are loosely controlled by it.

    I've never had a problem with C.G. & E., that eventually became Duke Energy, nor any of the "Co-ops", bringing in the properly sized Service to the buildings that I worked on.

    But South Central Power has pulled some "Wankers" a few times over the years.
