I usually have jobs where an engineer does all the figuring, but not in this case.
I have to quote a service and feeders for a portable classroom building. It consists of 13 - 13'wide mobile sections.
11 of the sections each have a 125 amp 1ph load center with lights, recepts and a wall pack hvac unit with 10kw of electric heat.
2 of the sections have a 150 amp 1ph load center with lights, recepts and a wall pack hvac unit with 15kw of electric heat.
I want to furnish a 208/120Y service with the appropriate feeders to each section.
How do I size the main service disconnect and distribution panel? Is there a demand factor that applies here? Otherwise I can build a 1000 amp service, but that seems like overkill.
Thanks in advance...!
