a feeder was ran to a small shed to hold a 240 volt air compressor, 1 receptacle and a heat lamp
The feeder input is 2 hot wires and a ground at 240 volts flood for the compressor, but I needed to step down the voltage to 120 for the heat lamp and single gang 20 ampere receptacle
When deciding whether to install the system bonding jumper in the transformer x output or the transformers secondary breaker box (separately derived system first point of disconnect), I chose the transformer by connecting the transformers x2,x3 and derived neutral wire to all EGC in transformer
Or I could have left grounds at transformer connected together and to case but separate from neutral connection at transformer and just bonded neutral to ground buss at downstream breaker box for secondary protection with neutral buss empty
I did not do the latter because of the lack of space in one ground buss and confusion it may have caused to another worker.
What do y’all think?
