DC Installation earths
Hi,

If you have a 48 volt DC system and the positive is earthed. What is the formula to work the size of the earth conductor to the equipment out? You can't have it the same size or bigger as your powerconductor because then the current will return through the earthconductor.

Thanks,

Johan
