Control panels, set and field wired
Industrial control panels are built and listed by a UL 508A panel shop or by the equipment maker. Our part is everything after the panel arrives: setting it, feeding it, running the field wiring to the motors, sensors and devices it controls, and being there when it starts up.
What the work involves
A UL 508A panel shop or the equipment maker builds and lists the panel, and we install it. We set it with the working space the code requires, feed it from a circuit sized to its nameplate, check the available fault current against its marked short circuit current rating, run and label the field wiring, and stay through startup.
The panel itself is built and listed by a UL 508A panel shop or the equipment maker, and NEC Article 409 covers industrial control panels and the short circuit current rating marked on them. We do not build listed panels; we install them and wire them in the field.
The panel is set where the drawings place it, with the working space in front of it the code requires, and fed from a circuit sized to its nameplate. The available fault current at the panel is checked against its marked short circuit current rating before it is energized.
Field wiring runs from the panel to the motors, valves, sensors and operator stations it controls, in raceways kept separate from power where the drawings call for it. Every conductor is terminated and labeled to the panel builder's drawings, so a fault can be traced from the drawing to the device.
Before startup we check continuity and terminations against the drawings, confirm motor rotation with the equipment's representative, and stay through startup to correct field wiring the commissioning finds. The programming belongs to the panel builder or the integrator.
Inside the city, the installation is permitted and inspected through the City of San Antonio Development Services Department under the 2023 NEC the city adopted effective May 1, 2025. The inspector looks at the listing label, the working space and the feeder.
The common problems are a panel whose rating is below the fault current where it is installed, field wiring that does not match the drawings, and control wiring pulled with power. Checking the rating before energizing, wiring and labeling to the drawings, and separating control from power prevent them.

No. Listed control panels are built by a UL 508A panel shop or the equipment maker. We set, feed and field wire them.
