How do I pick the right disconnect for 480v temporary service at a construction jobsite?

What size service are you planning? Or will this disconnect set the service size? What size new building and will there be any office trailers?

Sorry about that question. I was too tired to remember that it's 115% of full load.

To size a service disconnect, it needs to be rated 125% of the continuous plus the non-continuous load.
