I have a project with the border patrol that they have these little office trailers on their checkpoint sites. These sites are where you get checked by the Border Patrol when coming to and from Mexico.
There is not any conventional electrcity near the site and they want to feed one trailer with two generators. Each generator will produce about 83 amps and has a 50A breaker and a 20A breaker to use on them. One generator does not satisfy the trailer load - so two is needed. There is one panel on the outside of the trailer w/ a 125A main breaker. The trailor load is about 95amps.
My question is - Can this be done? Article 230 of the NEC states that there should only be one source per building. There are some exceptions within ART 230 but I don't think none of them apply. The only one of the possible exceptions within 230 that might apply is "parallel power feeds", but I don't think that even applies.
Other artices - 550 to 552 - have some provisions to mobile homes, but it doesn't give specifics about the use of multiple generators as the primary source for electrical power to a building.
Splitting up the load and adding some to a new panelboard for the trailer will do the trick. One generator for one panel. Another one for another panel. But I don't think this is NEC compliant.
They ordered these trailers and generators already where they want to use these generators that they have an abundance of.
I told them the simple way to do this is give back the 20KW generator and get a 30KW generator for the trailer. But they still want to use these generators.
Any help would be appreciated.
Thank You
