Frequently Asked Questions
No marketing fluff. Just the technical facts you need to specify the right enclosure and keep your project moving.
How do I calculate PLC enclosure size for my project?
Never size your enclosure based purely on the physical footprint of your hardware. Map out your PLCs, VFDs, power supplies, and terminal blocks on the backplate, and then add a mandatory 30% margin.
You need this extra clearance for three critical reasons. First, it accommodates wide wire ducts and proper bend radii for thick power cables. Second, it ensures adequate convection clearance so heat can dissipate from CPU heat sinks. Third, it acts as a built-in PLC enclosure sizing guide for future expansion, leaving room for additional I/O modules.
Squeezing hardware saves $50 in metal but costs thousands in overheating and maintenance.
Can I buy a NEMA 12 enclosure now and upgrade it to NEMA 4 later?
Do you provide Factory Acceptance Testing (FAT) documentation for my auditors?
Yes. We know your QA department and field inspectors will demand proof. Every custom enclosure leaves our floor with a complete, serial-numbered compliance dossier. This includes Material Test Reports (MTRs) tracking the exact heat/batch of the steel, dimensional QA sign-offs, and IP/NEMA integrity test certificates. You simply hand this packet directly to your safety auditor or client.
