One Of A Kind
Switchgear

Prime Power started operations in 1983 manufacturing custom switchgear for the region's most discriminating and demanding customers. With engineers on staff who trained under Prime Power founder Roger Bisher, the trademark quality and excellence of early Prime Power systems is still found today in our custom switchgear.

Prime Power engineers continue to design, install, test, maintain and sometimes manufacture intelligent switchgear, and we have done numerous switchgear retrofits and upgrades for large companies.
