Earth Fault Loop Impedance with Safety Generator
Former Community Member
Do I take this into consideration? If so how do I size wire in a building with a safety generator? What is my "Ze" when the supply switches from DNO to the safety generator? How do diesel generators behave during faults?
There are many posts on this elsewhere on the forum, search generator, you may like to read them. The Generator will almost certainly require an Earth fault relay (large RCD) and your carefully calculated disconnection times will probably increase. There is little you can do to change this, but power is probably better than no power.
