In a production environment the cost of an electrical problem is measured in downtime, not in labour hours. APEX Electric supports manufacturing and logistics facilities with power distribution, motor control, drive and controls work — planned around your production schedule and documented so your maintenance team can support it afterwards.
New equipment brings new load, and the existing distribution rarely has room for it without study. We size feeders, verify available fault current, and confirm the overcurrent protection is coordinated before anything is energised.
On the motor side we install and troubleshoot starters, motor control centres and variable frequency drives, including the harmonic and shielding considerations that determine whether a drive installation runs cleanly or generates nuisance faults for years.
We build and wire control panels, integrate PLCs and remote I/O, and land field devices to a drawing set that matches what is actually installed — which is not always the case with equipment inherited from a previous integrator.
You get updated as-builts and panel schedules at handover, so the next person to open the cabinet is not reverse-engineering it.
Machine relocations, line expansions and equipment tie-ins get scheduled into your planned downtime. We pre-fabricate what can be built off-line so the work performed during the shutdown window is only what genuinely has to happen there.
For ongoing reliability we run thermographic surveys of distribution equipment and motor connections, which finds developing faults while they are still a scheduled repair rather than an unplanned stop.
Available across O'Fallon, St. Charles, St. Peters, Wentzville and the rest of St. Charles County.
(660) 342-5886The things people ask us most about this work.
Yes, and we plan for it. Pre-fabrication and staging before the window means the on-site work during the shutdown is only the portion that requires the equipment de-energised.
Yes. Updated panel schedules, one-lines and control drawings are part of handover on every controls and distribution project.
Yes. We regularly take on inherited systems, document what is actually installed, and correct it.
Yes — scheduled thermographic surveys, torque verification, and panel and motor connection inspection, with a written report and corrective recommendations.
