Hi everyone,
I have a project with primary metering at 13.2kV on overhead utility line. The plan is to keep going overhead and feed 3 pad mounted transformers: 1000kVA, 1500kVA, and 2500kVA. I have done this type of work on underground lines many times but have some thoughts about overhead distribution.
Questions:
#1 - do I just tap from the line and install disconnect on a pole for each transformer?
#2 - only one disconnect per pole can be installed or 2 i.e. one underneath another?
#3 - should the disconnect be fused? I only found unfused disconnects but not sure how it will protect 13.2kV conductors down to transformer (if they even need to be protected)

I will appreciate any feedback on this.
Thanks
