service upgrade

Through the years, new appliances, electrical equipment, convenience outlet and lighting fixtures are added to suffice the needs of property owners or tenants and in the process; the electrical service panel becomes inadequate.


The amount of electricity that is available is limited by the ampacity of the main breaker. ESP, Inc. do load calculation, actual load measurement on peak-hours and power quality testing to determine the best possible service that our client needs. We have done upgrades from the simple residential panel upgrade, mostly from 100A to 200A 120/240V 3W single phase, to a more complicated commercial/industrial switchboard upgrade ranging from 1250A to 2500A 480V/240 4W three phase systems.
