Services & Feeders in Depth
5:18
Everything from the utility to your main panel is a service — everything after is a feeder.
In this lesson: the service vs. feeder distinction, the one-service-per-building rule and its exceptions, the 100A minimum dwelling disconnect, the 6-disconnect rule, overhead vs. underground service clearances, service conductor overcurrent protection (230.90), the grounding electrode connection, SE cable vs. raceway, and why service and feeder sizing use nearly identical math.
Based on the 2023 NEC (Articles 230, 215).
