Power distribution
Power distribution and generator control panels
Generator source and alarm panels, transfer and distribution assemblies, UPS panels and 690 V panels, built through our shop's UL 508A program, with drawings from our own engineering team.
Generator source and alarm panels
A remote generator source alarm panel shows the state of each generator circuit breaker and automatic transfer switch away from the generator itself. We design each one to the job: indicator lights per breaker or transfer switch, an audible alarm with a pushbutton, and front-panel legends taken from the project's electrical drawings, in 12 VDC or 24 VDC control. Submittal drawings go to the customer for approval before the panel is released to the shop. Generator source alarm panels for a standby-power dealer →
Transfer and distribution assemblies
Enclosed manual transfer switches, and breaker enclosures that split one generator feed into protected outputs, in indoor and outdoor (NEMA 3R) enclosures. We turn an installer's sketch into drawings, source the switching and protective devices, and work through revisions with the installer and contractor before the order is placed.

UPS panels
Panels and cabinets built around a UPS and battery backup, so control and communications equipment stays up through an outage. Our outdoor network cabinets for a utility communications program each carry a UPS whose battery charging we confirm on every unit before it ships. Read the case study →
690 V panels
For a drive manufacturer's factory test floor we built 690 V multi-drive test panels and a 690 V breaker panel, with molded-case breakers on rotary operators and open-style power distribution blocks rated 1000 V, alongside 480 V test and load panels. Test-cell power and control line-up →
Power-factor correction and harmonic filters
The shop also builds power-factor correction and harmonic-filter panels, and we supply the capacitors that go into them. Power-factor and harmonic-filter panels →
Ratings and listings
Distribution equipment is often installed close to the service, where the available fault current can be high, so the short-circuit current rating is worth settling early. SCCR, explained →
If your specification calls for a particular UL listing, for example for transfer-switch equipment or switchboards, include it with your request so we can confirm what applies to the build.
What to send for a quote
A one-line diagram or sketch, the sources and loads with their ratings, voltage and phase, the available fault current, indoor or outdoor and the enclosure rating, any required brands, and the quantity and date. What to send for a panel quote →
