We manufacture a complete line of low voltage power distribution switchboards featuring bolt-on circuit breakers, fusible
switch units and motor controls. We use an enhanced distribution bussing system, originally designed in the 1950’s, which
allows us to accommodate any combination of bolt-on circuit breakers, fusible switches, and/or motor controls mounted in
the same distribution switchboard section. Our bussing is precisely punched and tapped for future additions. We stock an
extensive inventory of circuit breakers and field installation hardware kits to support our customers’ needs for quick
shipments. We typically have a larger inventory on the West Coast than anyone else in our industry – including our
vendors. We do not adhere to Just-in-Time inventory practices so that we can better support our clients.
The switchgear pictured was a field upgrade/replacement for a 6000 Ampere Main-Tie-Main switchboard originally installed in
the early 1960’s. The replacement switchboard was re-configured as a main-tie-main-tie-main-tie-main with four 3000 Ampere
main breakers, two 3000 Ampere tie breakers and one 5000 Ampere tie breaker. The fully automated Load Managertm Control, is
responsible for continuous monitoring and control of the four sources. The main breaker controls also include sync-check
controls and capabilities because the four main sources are derived from upstream utility/generator automatic transfer
breakers to ensure that reliable service to the loads is maintained.
