Custom control panels, built in our shop
Electrisource designs and builds large custom industrial control panels in our 6,000-square-foot Berlin, Connecticut shop — and ships them direct to customers across the United States. Build and ship, or build and install: your choice.
What we build
Industrial control panels, engineered and assembled in-house
Our shop specializes in control panels built around programmable logic controllers (PLCs) and variable frequency drives (VFDs) — from single-enclosure builds to large multi-section panels. Every panel is fabricated by the same people who install and commission control systems in the field, so panels arrive built the way installers and maintenance staff need them.
- PLC control panels
- VFD and motor control panels
- Relay and interlock panels
- Large multi-section control enclosures
- Control panel replacements for legacy systems
- Panels built from customer drawings and specifications
How it works
Build & ship, build & install, or design-build
Three ways to put our panel shop to work, depending on how much of the project you want us to carry.
Build & Ship
Send us your drawings and specifications. We fabricate, wire, label, and check the panel in our shop, then crate it and ship it direct to your facility or job site — anywhere in the United States.
Ideal for out-of-state customers, OEMs, and contractors who handle their own installation.
Build & Install
We build the panel in our shop, then our own licensed electricians deliver, set, wire, and commission it in your facility — one contractor accountable for the panel from fabrication through startup.
Ideal for Connecticut and Northeast facilities that want a single point of responsibility.
Design-Build
For select panel projects, we take on the design as well: developing the panel layout, component selection, and drawings from your process requirements, then building to the design we produced.
Ideal when you know what the system needs to do but don't have finished panel drawings.
Our process
From drawings to a panel on your floor
01
Review & planning
We review your drawings, specifications, and requirements — or develop them with you on design-build projects — and lock down components, layout, and schedule before fabrication starts.
02
Fabrication & wiring
Panels are assembled in our shop under controlled conditions: back-panel layout, DIN-rail components, wire duct, point-to-point wiring, and clear labeling throughout.
03
Quality checks
Every panel is inspected and function-checked against its drawings before it leaves the shop, and documentation ships with the panel.
04
Ship or install
Your panel is crated and shipped direct to your site — or delivered and installed by our own field crews, wired, and supported through startup.
Why shop-built
A better panel than one built in the field
Building in a controlled shop environment means consistent workmanship, proper tooling, cleaner wire management, and quality checks before the panel ever reaches your site — which translates to less field labor, shorter disruption to your operations, and a panel your maintenance team can actually work on.
See it happen
Watch a shop-built panel go in
A one-minute timelapse from a recent project: a control panel built in our shop, delivered to the site, and installed in place of the equipment it replaced. This is what build-and-install looks like — the panel arrives finished, and field time goes to setting, terminating, and commissioning instead of building.
Panels ship nationwide from Berlin, Connecticut. Installation is available throughout the Northeast — and beyond for the right project.
