Hello all.
Couldn't resist on the title.
I'm being asked by a customer to start planning for a generator installation. They have already purchased the generator, but it has not yet arrived. It is a 250KW diesel with a nameplate 277/480V amperage of 375.9. I do not yet know if it has overcurrent protection.
The requested installation would supply three separate buildings, each with their own utility service. The customer is requesting manual transfer switches.
These services are all 277/480V.
My current plan is to feed a panelboard with the generator and split off to each of the three services. My main concern revolves around the transfer switches. I've been researching when the neutral is required to be switched. I don't think it needs to be in this situation but the more I read of the fifty bajillion articles on this topic, the more the little nagging voice in the back of my mind gets louder and I'd like some other opinions.
Thank you.
