When will we use NEC tables 220.12 and 220.42 for lighting load calculation? I thought we do the lighting load calculation based on whatever is allowed by IECC (International Energy Conservation Code)?

When sizing the service or feeder, the energy code says nothing about the min calculated load for sizing service conductors and feeders (distribution loads)
