My experience is in individual motors and controls so would like to reach out to folks involved in this kind of work. There is a local school here that needs to upgrade (increase size) the present 400 amp service, mainly to allow air conditioning it. The school board is saying the cost will be well over $ 500,000.00 and must be done by the local POCO. This estimate seems outrageous to me. And it seems the work (from the POCO drop spot outward) might be done by non POCO private companies. If this estimate and 'can only be done by POCO' is way off base, I would like to investigate and correct the local school board.
