I have a situation where a three phase service is brought into a building. The existing loads are single phase and are bussed together using only two phases. There is no way to change the bussing in the existing metering packs. How do I balance the loads without changing the entire metering pack?

Greetings,
Could be difficult. What type 3 phase service? 120/208 or 120/240. If it's 120/240 it is no problem most likely.

Agreed but given the OP's question very likely not a delta where the high leg tranny can be left idle.BSSTG said:
Sounds to me like a typical 208y/120 service feeding a multi meter/ main pack for dwelling units. (condo's apt's)
That said the best one can do is;
Unit 1 AB
Unit 2 BC
Unit 3 CA
ect...
Now look at the house PNL and try to put that load on the least of the to loads on the dwelling unit loads.
I am unaware of any code requirement that states service loads "shall be" balanced.
