Wouldn't that mean that when the generator was running, that the meters would still be turning in the power company's direction?
thanks - If I CANT put a transfer AHEAD of the premises metering - then would there be any other way to provide backup power to three meters off one backup generator?
Dual lug on load side of meter, maybe?:roll:
I think you would have to put in three transfer switches so as to transfer the Service Feeders to the Generator upon loss of Utility power. The generator start contacts in each switch would need to be wired in parallel. Installing three switches will definitely raise the cost of the installation but I don't know of another way.thanks - If I CANT put a transfer AHEAD of the premises metering - then would there be any other way to provide backup power to three meters off one backup generator?
Thats a good question, Frank. Not sure on this one.
Im wondering how, if at all possible, to provide backup protection for a single commercial building with 3 meters (each serving a single floor); off on one single generator.
Bob that was my first thought but i started to think what happens if power goes off on one unit and not the others. That's why I thought you would need one main one ahead of the meters. When that went off then the generator would kick in and feed the wires from the other transfer switches.You would need three transfer switches connected to the single generator. Not that usual.

Help me with the hookup if you will. Do all three units have to loose power to energize the genny?
Assuming they are Automatic Transfer switches set up for two wire start you would just put all the ATS start contacts in parallel so if any one ATS lost normal power the generator would start.
If for some reason one units main blew and the other two still had power the one ATS without power would transfer and the other two would remain in the normal position.
We often install single generators that supply both standby and emergency loads, that means we must have at least two transfer switches.
We have also placed large generators that supply two buildings with transfer switches in each building.
Short of a more elaborate setup, perhaps putting the "run" contacts in series is better.The only down side to the whole set up is if tenant #2 didn't pay the power bill and poco came and booted the meter then the gen will run and transfer to tenant #2. But there is no other way around it.
