How to Size a Neutral Grounding Resistor

One of the most critical decision when designing stable and safe electrical systems is system grounding. The key parameter that determines the neutral grounding resistor’s affect on the circuit is the let-through current. This video will focus on how to determine what level of let-through current to specify when designing a resistance-grounded system.
