Good volts but low power output

[crewdog89]

I'm having a problem with the electric running to my shop. I have electric, but when my compressor or chop saw is running, the lights go extremely dim, and the saw is not running at full speed. The compressor is struggling when it is trying to build up. I've checked the voltage at the circuit breakers, and they all read 120V. If I run these components from an extension cord from the house, everything works normal. The wires running from the meter to the shop look fine, and nothing appears to be loose. Any advice would be much appreciated.

Is the supply between house and shop belong to the utility company.

Not sure. I'll have to call them and ask.

The supply at some point is almost certainly breaking down.

Your wire is to small for what you are trying to do? I’m curious what size wire do you have going out to your building

what's the betting its a lose connection or breaker not in correct .I also think those tails are not in the isolator .

could be the fire wire nut

I just looked at the big picture looking a the catinary wirer me thinks the hot or cold is wired to it ,holy f88K.BAT MAN .

I wonder who wired that, me thinks jumping jack flash.

Wired to what Buzz?

the wire is looping in but comes out to the cat wire ,I might be wrong .

Yes I see what you mean.

It appears (in UK terminology) that the two lives are insulated with a bare PEN conductor doubling as the catenary wire.

I'm thinking along those lines. That could be a bare aluminium conductor with a few steel cores to support it. The two cores looped around the support look a different material.

If you look close the two black overhead conductors pass straight into the building, the third is connected to the bare conductor.

Crew dog from looking at the picture of the wire feeding your building it appears to be done by someone not the power company, ( they don’t use split bolts ). It’s looks plenty big enough but is it copper or aluminum?

westward that Bare conductor does have 2 strands of hard steel, which is the grounded conductor, then we drive 2 rods in earth and bond that back to the main panel
