Electrical panels sit at the center of every industrial operation. Yet, many plants face downtime due to poor panel design, inconsistent build quality, or non-compliance with standards. These issues raise safety risks, increase energy losses, and cause repeated failures during audits or expansions.

The risk grows when panels are sourced without clear certification, testing discipline, or proper engineering review. Inconsistent wiring, undersized components, and unclear documentation often lead to unplanned shutdowns and high maintenance costs.

A structured electrical panel manufacturing process solves these challenges. PIMA Controls supports industries with certified panel manufacturing, authorized components, and tested automation systems. With 35+ years of experience, PIMA delivers panels built for reliability, compliance, and long-term plant performance.


What Is Electrical Panel Manufacturing?

Electrical panel manufacturing is the structured process of designing, assembling, wiring, testing, and certifying control and power distribution panels used in industrial and commercial facilities.

These panels control motors, drives, instrumentation, power distribution, and automation systems. They form the interface between electrical supply, automation hardware, and field equipment.

A professional panel manufacturing company follows documented engineering practices, approved components, and compliance standards to ensure safety and performance.

Common Types of Electrical Panels

Industrial facilities use several panel categories based on application:

  • Motor Control Centers (MCC panels)

  • Power Control Centers (PCC panels)

  • PLC automation panels

  • VFD and soft starter panels

  • APFC and energy management panels

  • Instrumentation and junction panels

PIMA Controls manufactures all major panel types under ISO processes and UL 508A certification, supporting OEMs, EPCs, and plant owners across India.


Electrical Panel Manufacturing Process Step by Step

A structured manufacturing process ensures repeatability, safety, and audit readiness. Each stage plays a direct role in final panel quality.

Requirement Analysis and Application Study

Every panel project starts with a technical review. Engineers analyze:

  • Load requirements and power ratings

  • Control philosophy and automation scope

  • Environmental conditions

  • Compliance and customer specifications

This step prevents design gaps that later cause field issues.

PIMA works closely with consultants, EPCs, and end users to finalize functional requirements before design approval.


Electrical Panel Design and Engineering

Panel design converts requirements into engineering documentation. This stage includes:

  • Single-line diagrams

  • GA layout drawings

  • Wiring schematics

  • Component selection

  • Heat dissipation calculations

Authorized component selection matters here. As an authorized distributor for Rockwell Automation, Schneider Electric, AVEVA, and Rittal, PIMA uses original components with verified ratings and lifecycle support.

Design reviews also ensure future scalability and maintenance access.


Enclosure Selection and Mechanical Preparation

The enclosure protects internal components and supports heat management. Selection depends on:

  • IP rating requirements

  • Indoor or outdoor installation

  • Ambient temperature

  • Industry environment

Rittal enclosures are widely used due to thermal design and modular flexibility. PIMA integrates enclosure selection early to avoid overcrowding and thermal stress.

Mechanical preparation includes:

  • Panel mounting plates

  • DIN rail positioning

  • Cable duct routing

  • Cutouts for operators and meters


Component Assembly and Panel Wiring

This stage converts design into a physical system. Trained technicians assemble:

  • Circuit breakers and contactors

  • PLCs and I/O modules

  • Power supplies and relays

  • Drives and communication devices

Wiring follows color codes, ferruling standards, and torque specifications. Clear labeling improves troubleshooting and audit clarity.

PIMA follows documented wiring practices aligned with UL 508A and IEC standards.


Quality Control During Assembly

Quality checks occur throughout assembly. These checks include:

  • Component verification against BOM

  • Wire size and termination checks

  • Torque validation

  • Visual inspection of routing and segregation

Early quality checks reduce rework and improve delivery timelines.


Electrical Testing and Functional Validation

Testing validates panel safety and function before dispatch. Standard tests include:

  • Insulation resistance testing

  • Continuity testing

  • High-voltage testing where applicable

  • Control logic simulation

  • Communication checks

For automation panels, PLC logic and HMI functions are tested under simulated conditions.

PIMA performs internal testing followed by customer witness testing when required.


Final Documentation and Dispatch

Complete documentation supports installation and future maintenance. Deliverables include:

  • As-built drawings

  • Wiring diagrams

  • Component datasheets

  • Test reports

  • Compliance certificates

Panels are packed with transport protection to prevent damage during shipping.


Electrical Panel Manufacturing Standards and Certifications

Standards define safety, performance, and audit acceptance. Compliance is not optional in industrial environments.

UL 508A Certification for Control Panels

UL 508A is a globally accepted standard for industrial control panels. It defines:

  • Component selection rules

  • Short circuit current ratings

  • Wiring practices

  • Marking and labeling requirements

UL 508A certification allows panels to be accepted in export markets and regulated facilities.

PIMA Controls is a UL 508A certified panel manufacturer, supporting customers with export-ready solutions.


IEC Standards in Panel Manufacturing

IEC standards apply widely in India and other regions. Common IEC references include:

  • IEC 61439 for low-voltage assemblies

  • IEC 60204 for machinery safety

  • IEC 60529 for IP ratings

Panels built to IEC standards ensure compatibility with global equipment and inspection norms.


ISO Manufacturing Processes

ISO-certified manufacturing supports consistency and traceability. It covers:

  • Process documentation

  • Material control

  • Quality audits

  • Continuous improvement practices

PIMA operates under ISO-certified systems, ensuring repeatable quality across projects.


Quality Practices That Define a Reliable Panel Manufacturer

Quality goes beyond certification. It depends on discipline, training, and component integrity.

Component Authenticity and Authorized Supply

Unauthorized components increase failure risk. As an authorized distributor for Rockwell Automation, Schneider, AVEVA, and Rittal, PIMA supplies genuine products with warranty support.

This ensures lifecycle reliability and spare availability.


Skilled Panel Builders and Technicians

Panel assembly requires trained personnel. Skills include:

  • Electrical interpretation

  • Automation integration

  • Torque control and termination practices

  • Testing discipline

PIMA invests in continuous technician training aligned with evolving automation platforms.


Thermal Management and Energy Efficiency

Heat reduces component life. Proper thermal planning includes:

  • Panel ventilation

  • Heat load calculations

  • VFD spacing

  • Cable segregation

Efficient thermal design supports energy efficiency and reduces maintenance issues.


Traceability and Documentation Discipline

Each panel must be traceable. Serial numbers, test records, and drawings support audits and expansions.

Clear documentation also reduces downtime during troubleshooting.
