Hi,
I am wondering about how to size the conductor and OCPD for a single point power piece of equipment such as a large air dryer or chiller. They usually consist of several small pumps, heaters, controls, etc and come labeled with a full load current. For example, a dryer with122 full load amp. Do you have to take 125% of this for the conductor and breaker size, or is there another way to handle this load? It seems tricky since it acts like a branch circuit but has a number of loads on it so is also like a feeder. Thanks for any feedback.
