Electrical Control Panel Design Services
From concept to fabrication-ready drawings — industrial control panel design engineered for UL 508A compliance, built and certified under one roof.
UL 508A Certified Shop • U.S. Veteran-Owned • Las Vegas, NV
The design package
Schematics & wiring diagrams
Ladder and one-line drawings, wire numbering, terminal and cross-reference tables — a set a builder and an inspector can both follow.
Component selection & BOM
UL Listed and Recognized components chosen for duty, availability, and your approved-manufacturer list, released as a priced bill of materials.
SCCR calculation & documentation
Short-circuit current rating established by the UL 508A Supplement SB method, with the weakest-link path documented and labeled.
Enclosure sizing, thermal & layout
NEMA type selection for the environment, heat-rise calculation and cooling, wire-bending room, and a subpanel layout drawn to real component footprints.
PLC control panel design & I/O
Controller and I/O architecture sized to the sequence of operation — module counts, spare capacity, networks, and safety-circuit separation.
NEC 409 / UL 508A review
A compliance pass over the finished set — overcurrent protection, spacings, grounding, conductor sizing, and nameplate data — before anything is cut.
Drawn by the shop that builds it
Most design firms hand over a drawing set and walk away. Most panel shops build whatever arrives, then send change orders when it doesn't fit. Both models push the cost of a design error into fabrication, where it is most expensive to fix.
We do both. The engineer drawing your panel works twenty feet from the bench that will wire it, so component availability, wire-bending room, thermal load, and inspectability get settled on the drawing — not discovered on the floor.
Start Your DesignDrawings are correct on paper. Long-lead components, layout clashes, and SCCR gaps surface after the enclosure is already ordered.
The shop follows the print as issued. Errors become RFIs, change orders, and rework — on your schedule and your budget.
One accountable party from first sketch to certified panel. Buildable, inspectable, and certifiable by the time the drawings are released.
Four steps to release
Requirements & load review
Sequence of operation, motor and load list, available fault current, environment, and the standards you're held to.
Schematic & layout design
Drawing set, component selection, I/O architecture, and a subpanel layout drawn to real footprints and thermal load.
Review & SCCR documentation
A markup cycle with your team, then the compliance pass: SCCR study, protection coordination, and nameplate data.
Release to fabrication
Approved drawings go straight to our UL 508A shop — or to you, if the design is the whole engagement.
What does electrical control panel design cost?
Design is quoted as engineering hours against a defined scope, so cost tracks the complexity of the control system rather than a flat rate. A single-enclosure machine panel with relay logic and a small PLC is a modest, well-bounded package; a multi-section MCC with drives, safety circuits, and a full SCCR study is a larger one. Send your sequence of operation, load list, and any existing drawings and you'll get a fixed-fee proposal with the deliverables itemized.
Do you design panels you don't build?
Yes — design-only engagements are welcome. You receive the full drawing package, bill of materials, and SCCR documentation, and you're free to fabricate in-house or with another shop. Because we build panels every day, the package is written the way a builder needs to read it.
What software do you design in?
We design in EPLAN and AutoCAD Electrical, and deliver native project files plus DWG, DXF, and PDF sets. Bills of material export to Excel or CSV, and panel layouts can be issued as DXF for enclosure cutouts and nameplate engraving.
Can you redesign an existing panel to meet UL 508A?
Yes. We review the existing panel and drawings, identify what blocks compliance — unlisted components, undocumented SCCR, spacing and wire-bending room, overcurrent protection, and labeling — then issue a corrected drawing set with a component swap list. In most cases the same enclosure can be re-panelled rather than replaced.
How long does industrial control panel design take?
A straightforward machine panel typically moves from kickoff to released drawings in one to two weeks. Larger systems with drives, safety circuits, and a formal SCCR study usually run three to five weeks, including a design review cycle with your team. Fabrication in our UL 508A shop begins as soon as the drawings are approved.
