Services / Panel Upgrades & Service
Residential 100A/200A upgrades through commercial and industrial services past 2500A — subpanels, breakers, load calculations, meter cans, and service disconnects.
Overview
Panel and service work is one of our specialties. On the residential side, that means 100A / 200A upgrades, meter-can swaps, and subpanel additions for garages, workshops, ADUs, and pool equipment. On the commercial and industrial side, JSP has installed services well past 2500A — full switchgear line-ups, CT cabinets, main disconnects, and utility coordination with CenterPoint.
