Panel manufacturing (specifically electrical control panels and switchboards) is the process of housing, wiring, and organizing electrical components into a centralized unit. In 2026, the industry has shifted from manual “point-to-point” wiring to Digital Twin-driven manufacturing, where a virtual replica of the panel is created before a single wire is cut.
1. The Modern Manufacturing Workflow
The process is now highly integrated, connecting the engineering office directly to the factory floor.
| Stage | Technology / Process |
| 3.D Design & Digital Twin | Engineers use software like EPLAN Pro Panel or Zuken Panel Builder 2026 to design the panel in 3D. This simulates heat dissipation and ensures components fit perfectly. |
| Automated Fabrication | CNC machines (like the nVent PWA 6000) take the 3D data to automatically drill holes, mill threads, and cut notches in the metal enclosure. |
| Wire Processing | Instead of a technician measuring and cutting by hand, machines automatically cut, strip, crimp, and label every wire based on the digital model. |
| Smart Assembly | Technicians use Augmented Reality (AR) or digital work instructions on tablets that show exactly where each wire goes, reducing human error. |
| Testing & FAT | Factory Acceptance Testing (FAT) now often includes “Virtual Commissioning,” testing the logic of the panel against the digital twin before it’s even powered up. |
2. Key Industry Trends for 2026
-
The “Digital Twin” Standard: Most high-end panels now come with a digital twin. This allows facility managers to troubleshoot the panel remotely or simulate “what-if” scenarios without touching live wires.
-
Predictive Maintenance Sensors: Modern panels are no longer “passive.” They are equipped with IoT sensors that monitor internal temperature, humidity, and arc-fault signatures to predict a failure weeks before it happens.
-
Miniaturization: As components become more efficient and generate less heat, panels are shrinking. This is critical for space-constrained environments like urban high-rises or mobile EV charging hubs.
-
Agentic AI in Production: AI agents are now used to manage the “multiple build” process—tracking identical panel versions across a global supply chain and automatically updating documentation when a component is swapped for an alternative.
3. Standards & Compliance
Every panel must adhere to strict safety codes, which have been updated for 2026 to reflect the “electrification of everything”:
-
UL 508A: The primary standard for industrial control panels in North America.
-
NFPA 70 (National Electrical Code 2026): The latest edition includes new requirements for Surge Protection and Energy Management within the panel.
-
IP & IK Ratings: Panels are rated for their resistance to dust/water (IP) and mechanical impact (IK), ensuring they survive in harsh industrial environments.
4. Common Types of Manufactured Panels
-
MCC (Motor Control Centers): Used in factories to control banks of heavy motors.
-
APFC (Automatic Power Factor Correction): Panels that use capacitor banks to improve electrical efficiency and lower utility bills.
-
Distribution Boards: The “main” panel that splits power into various circuits for a building.
-
PLC Panels: The “brain” of a machine, containing the controllers and I/O modules for automation.
