Feeder service capacity for additional loads is typically considered as what percent?

Explanation:
The idea here is to leave headroom in the feeder design for future growth. In practice, about 40 percent of the feeder’s capacity is reserved for additional loads. This gives a reasonable cushion to add equipment or circuits later without immediately upgrading the service, while avoiding the expense of oversized feeders from the start. If you use a much higher percentage, you’re paying for more unused capacity; if you use a lower percentage, you risk running out of capacity as loads are added.
