NOTES: The neutral conductor should be sized for 1,5 times the output/bypass phase current. The Earth
conductor should be sized at 2 times the output/bypass conductor (this is dependent on the fault
rating, cable lengths, type of protection etc.) These recommendations are for guideline purposes only
and are superceded by local regulations and codes of practice.
