Back to Industrial Automation
Control panel design is the process of engineering an electrical enclosure that safely houses and connects PLCs, relays, circuit breakers, power supplies, VFDs, HMIs and terminal blocks to control industrial machinery and processes.
Our design process
- Requirement definition — supply voltage, load details, PLC I/O, environment, applicable standards (IEC, UL, NFPA)
- Single-line diagram (SLD) — incoming power, main breaker, distribution, protection
- Electrical schematics — control circuits, PLC wiring, relay logic, safety and E-stop circuits
- Component selection — PLC, power supply, MCB/MCCB, contactors, overload relays, VFDs, HMI, terminal blocks
- Panel layout — maintainability, heat dissipation, cable routing, power/control separation
- Cable management — segregated routing, wire ducts, ferrules, full labelling
- Heat calculation — ventilation fans or panel AC sized to component heat load
- Protection & safety — earthing, surge protection, correctly rated breakers, E-stop, lockout/tagout
Control panels
- PLC control panels — automated machine control
- Motor Control Centers (MCC) — multiple motor control
- VFD control panels — variable-speed motor control
- DOL starter panels — direct-on-line starting
- Star-Delta starter panels — reduced starting current
- Automatic Transfer Switch (ATS) panels — utility/generator changeover
- Distribution panels — power distribution to multiple circuits
Power panels
- Main Distribution Boards (MDB) — utility/transformer intake and distribution
- Sub Distribution Boards (SDB) — downstream distribution to smaller loads
- Low Voltage (LT) panels — up to 1,000 V AC industrial and commercial
- Power Control Centers (PCC) — power distribution and control to feeders
- Motor Control Centers (MCC) — motor supply and control
