We will be doing a project (still in planning) to upgrade a service that is a 240volt high leg service. There are minimal 3 phase loads in the building ( ac compressors, roof fans, and little more). There will be an expansion of single phase loads in the future, currently the majority of the circuits are single phase so there are alot of unused B phases in the panel. The POCO doesnt want to change there configuration. Is it a bad idea to set a transformer with a second panel to allow for expansion of the new load, or does anybody else have a better solution, or should I push the poco to upgrade there end to a 120/208Y. The building is mostly office space with a repair and machine shop that has 3phase equipment. Thanks in advance
