Maintenance for Critical Electrical
& Control Systems 

Preventive, corrective, and emergency support that keeps your operation safe, compliant, and online—24/7. 

Why PWC for Maintenance 

  • Critical-infrastructure focus. We maintain high-demand environments where uptime and safety are non-negotiable. 

  • Electrical + controls under one roof. From 600 V distribution to 4–20 mV signals, we service the full stack. 

  • Industries We Serve. Airports, amusement/theme parks, fulfillment & distribution, data centers, commercial, and manufacturing facilities. 

  • Code-compliant practices. Maintenance that aligns with modern standards and rigorous operational requirements. 

Maintenance Programs 

Preventive Maintenance (PM) 

  • Scheduled inspections and cleaning 

  • Torque checks on terminations & bus connections 

  • Thermal imaging for early fault detection 

  • Battery, UPS, and power quality checks 

  • Control panel integrity & enclosure health 

Predictive & Condition-Based 

  • Vibration/temperature spot checks on critical assets 

  • Trend logs and exception reports 

  • Recommendations before failure 

Corrective & Emergency 

  • 24/7 troubleshooting and repairs 

  • Fault isolation and safe return-to-service 

  • Replacement parts sourcing and fit-for-purpose upgrades 

Controls Care 

  • PLC/HMI health checks and backups 

  • I/O verification and sensor calibration 

  • Network integrity (switches, cabling, labeling) 

  • Firmware and patch management windows 

Compliance & Documentation 

  • NEC/NFPA-aligned maintenance records 

  • Lockout/Tagout (LOTO) verification 

  • Test reports and close-out packages for audits 

What We Service
