Cost
Shop hours beat field hours
Bench work happens at a workbench with every tool in reach. Field work happens on a ladder with the parts you happened to bring.
Custom panel builds
A panel that was already proven before it left the shop.
We build custom control panels to your drawing set or ours. Every one of them is powered, loaded, and exercised on the bench before it ships, and the test record ships with it.

Why it matters
Find it on a bench, not on a roof in January.
A wiring error caught during factory acceptance testing costs an hour of shop time. The same error found at startup costs a truck roll, a lift rental, an electrician, and a day of everyone's schedule. That arithmetic is the whole argument.
Schedule
Startup becomes checkout
A tested panel arrives ready to land. Startup turns into verifying field wiring instead of debugging the panel and the field at the same time.
Risk
One variable at a time
When the panel is known good, a problem at startup is a field problem. That is a much shorter troubleshooting conversation.
Build and test sequence
What actually happens to your panel.
-
Drawing set first
Nothing gets cut or drilled until there is an approved layout, a schematic, a terminal schedule, and a bill of materials. If we are building to your drawings, we review them and come back with questions before we start, not after.
-
Enclosure and layout
Back panel laid out with clearances that let a technician work: controller, power, and field terminals separated, wire duct sized for the day somebody adds points, and spare capacity built in for the next phase.
-
Wiring and labeling
Every conductor landed, dressed, and labeled. Printed terminal markers, not a paint pen. The number on the terminal matches the number on the drawing, which matches the number the electrician will be looking for.
-
Power-up and continuity
Insulation resistance and continuity checked before anything energizes. Then power applied, supply voltages verified at the load, and grounding confirmed.
-
Station loaded
The actual station goes in, not a test program. Controllers are addressed, licensed where required, and the network trunk is proven end to end at the terminals where field wiring will land.
-
Inputs simulated
Analog inputs driven across their range with a signal source and confirmed at the graphic. Binary inputs toggled at the terminal. Every point checked against the point list, including the ones nobody expects to use.
-
Outputs commanded
Every output driven from the station and confirmed at the terminal: relays pull in, analog outputs land on the commanded voltage or current, and interlocks behave the way the sequence says they should.
-
Documented and shipped
The FAT record is signed and travels with the panel. Drawing set in the door pocket, backup file delivered to you, and any punch items closed before it goes on the truck.
What we build
One-off, or the same panel forty times.
Repeatable builds are where a shop earns its keep. If you have twenty identical rooftop units or a portfolio of buildings on the same standard, the second panel costs meaningfully less than the first.

- Identical builds for repeatable rollouts
- Compact enclosures for above-ceiling mounting
Retrofit
Retrofit and replacement
- Cans sized to the space and conduit you already have
- Terminal arrangements that match the existing field wiring
- Cutover planned so the building stays conditioned
Specialty
Refrigeration and specialty
- Supermarket refrigeration rack interfaces
- Generator, metering, and utility monitoring panels
- Process and light industrial equipment interfaces
Ordering
What we need from you to quote it.
Send any of these
- A point list or an equipment schedule
- The mechanical drawings and the controls spec section
- Your existing panel drawings, if you have a standard
- Photos of the panel being replaced, plus its available space
- Quantity and delivery dates, even approximate ones
- Any owner standard the panel has to conform to
Electrical scope stays with the electrician
We build and test the control panel and provide the drawings that go with it. Feeder sizing, disconnects, permits, and installation inspection remain the responsibility of the electrical contractor and the authority having jurisdiction on your project. We will coordinate with them directly and give them what they need.
Lead times, honestly
Panel lead time is driven by component availability more than by shop capacity. We quote a real date based on what is actually orderable that week, and we tell you when a long-lead item is the thing setting the schedule.
Next step
Send the schedule. We will send the number.
One panel or forty. Your drawings or ours. Either way you get a fixed price and a delivery date you can put on a schedule.
