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.

Save money – and get reliable intersystem bonding between power and communication grounding systems.
Four termination points – one more than required by 250.94 of the 2014 NEC – handle multiple hookups of communications systems like telephone, CATV or satellite dish.
Back when we renovated the house, one of the top priorities was
upgrading the electrical system. The house was built back in the 60s,
and the electrical system was a mess, to say the least. Well, maybe not a
total mess, but definitely outdated.
