Re: Exposed High Voltage Transmission Conduit
Posted by gfretwell:
Did you excavate it or is this erosion?
If it is erosion I would start with the PoCo and then escalate up through the utilities commission and the political structure.

I agree with you.

How do you feel IF the sub has only 4 single pole branches?

Re: Out building grounding
Posted by SilveradoDriver:
I have a friend that has an out building with a 100 amp panel on the outside of the structure. The thing has been there forever and it's not raintight/weatherproof. He wants to change out the panel. This sub-panel is about 100' from the from the main panel. The ground looks to be #6 (...)

  • 13A through 0.75mm² flex - 10.5W/metre max. (2 load wires * 0.0267R/m at 20C * TCR 1.16 (...)
Re: Contactors, 208v, 240v lighting questions.
Posted by gfretwell:
Just as gee whiz info, these are the transformers behind the Hogs Breath in Key West. The first thing that got my attention was that one was bigger than the other two and then I look at how they were connected. The fatter one is center tapped. This is the only time I have seen red leg delta (...)
Re: Outdoor transformer/grounding question
Posted by Sparky42:
Hmmm, the breaker box is mounted on a metal building. Can I consider the breaker box as the source location? In that case there is a ground wire connected to the breaker box itself (and it comes out via the IEC-309 connector). This is not a permanent installation it will only be active for (...)
