Below is a picture of a 1960 Electrical Installation I am trying to fix without pulling new conductors through a conduit.
We have a 120/240 VAC Single Phase panel in the Field fed by a FA 36100 208Y 120 3 Phase breaker 950 feet away. I think we have 2 120 VAC Hots and a Neutral coming from the Breaker without a Ground Conductor?
Am I correct? Can anyone comment on what's going on here?
The conduit is 950 feet long. Its under a huge parking lot and I don't think we can run new conductors
Can I take the existing conductors and remove them from the 3 phase breaker and convert them from H1, H2 and N to become H, N and G?
This way I will have a Ground Conductor from the source panel.
The problem is I would be on a 120 VAC Single Pole breaker. With the 950 foot run and 6 AWG conductors, will I suffer too much line loss?
Does anyone have any ideal on what my options are? I have more pictures if needed.
I haven't put a meter on the field panel to see what's going on with H1 and H2. Would that help?
