Question:
When determining the total connected load on the main service, is there a section in the code that allows to derate the connected load by a percentage due to intermittent duty of designated motors? Approx.30% of the plant motors will be in operation at one time. Trying to minimize the main service size.
Thank you, John R. Harris

Answer:
Hey John thanks for your question. An AHJ is allowed to grant permission to use smaller conductors for multiple motors as stated in 430.26.
