Our Industrial Electrical Services

Whatever your facility demands, our industrial electrical capabilities are built to match it.

Power Distribution & Infrastructure

We build the foundation that keeps your facility running.

  • High-Voltage & Distribution: Safe, code-compliant industrial electrical installation of switchgear, transformers, and bus duct systems. As a specialized medium voltage electrical contractor, we’re qualified to handle the complex heavy-power terminations other contractors can’t touch.
  • System Design: Custom load calculations and heavy-duty industrial electrical wiring to support manufacturing equipment.
  • Backup Power: Turnkey installation of generators and UPS systems to ensure business continuity during grid failures.

Machinery & Automation

Modernize your production line with precision integration.

  • Equipment Hookups: Precision wiring for CNC machines, conveyor systems, and robotics.
  • Motor Controls & VFDs: Installation of Variable Frequency Drives (VFDs) to optimize energy usage for large motors.
  • Control Wiring: Seamless integration of automated control systems (PLCs and SCADA) with motors and drives for precise operation.

Safety, Planning & Compliance

Protect your workforce and minimize liability with strict adherence to safety standards.

  • Industrial Electrical Zoning: Expert classification and wiring for hazardous locations (Class I, Div I/II) to prevent combustion in volatile environments.
  • Code Compliance: Installations executed in full accordance with current NEC and OSHA standards.
  • Arc Flash Analysis: Comprehensive studies to identify hazards and protect your personnel.

Maintenance & Support

Minimize downtime with proactive care and rapid response.

  • 24/7 Industrial Electrical Support: Rapid response teams available around the clock for emergency breakdowns.
  • Preventative Maintenance: Thermal imaging audits and scheduled inspections to help catch electrical faults before they stop production.

Frequently Asked Questions

When do I need to upgrade my main switchgear?

Switchgear generally has a lifespan of 20-30 years, but you may need an upgrade sooner if you’re adding new heavy equipment that exceeds your current capacity. Warning signs include frequent breaker trips, buzzing sounds, or signs of overheating. Upgrading your switchgear not only improves reliability but also ensures your facility can handle modern industrial electric systems and automation without risking a total shutdown.

What is the difference between commercial and industrial wiring?

While commercial wiring handles standard office needs (lights, outlets, HVAC), industrial electrical wiring is engineered for much higher voltages and harsher environments. Industrial systems often require three-phase power to run heavy machinery and use rigid conduit to protect cabling from chemicals, heat, and physical impact. Our certified industrial electricians are specifically trained to handle these complex, high-load environments that standard commercial electricians cannot.

How often does OSHA require Arc Flash studies?

According to NFPA 70E standards (which OSHA enforces), an Arc Flash Risk Assessment must be reviewed at least every five years. However, you must update the analysis sooner if you make major modifications to your electrical system, such as adding new distribution boards or significant machinery. Keeping this current is critical for Code Compliance and ensuring your team has the correct safety labelling to work safely.
