Select capability, not just a catalogue phrase
A control-panel manufacturer should be evaluated against the actual system, documentation, component, enclosure, and service requirements. “Custom” or “industrial” in a company description does not prove compatibility with a particular PLC, drive, standard, environment, or commissioning scope.
Inputs to define before contacting suppliers
Prepare the process narrative, equipment list, motor and drive schedule, I/O list, control voltage, enclosure environment, incoming power, cable entry, drawings, labels, software boundary, inspection, testing, and delivery requirements. This lets each supplier quote the same scope.
| Evaluation area | Questions |
|---|---|
| Technical fit | Has the supplier built comparable control, VFD, PLC, pump, or distribution panels? |
| Documentation | Can it provide drawings, schedules, labels, and agreed handover documents? |
| Onderdelen | Are the proposed brands, interfaces, and availability acceptable? |
| Behuizing | Can it meet the actual material, mounting, cooling, and environmental needs? |
| Responsibility | Is programming, wiring, testing, and commissioning clearly included or excluded? |
| Support | Who handles changes, spare parts, defects, and future modifications? |
Do not treat a certification logo, project image, or product family as proof of the exact scope. Ask for evidence that matches the equipment and location.
Compare quotations consistently
Compare the same I/O count, feeder list, enclosure, component schedule, drawings, testing, packaging, delivery, and exclusions. Identify assumptions around field wiring, software, network integration, site work, and acceptance. A lower price may reflect a narrower responsibility boundary rather than a lower manufacturing cost.
ElectricalCabinet.net can use this checklist to structure a control-panel enquiry and route it to the appropriate PLC, VFD, pump, enclosure, or power-distribution capability.
