Electrical systems age quietly. Dust, debris, and vibration build up slowly over time. Bolted connections loosen under heating and cooling cycles. Left unchecked, these small issues turn into overheating, power loss, and equipment failure. That's why cleaning and torquing are essential parts of a professional Electrical Maintenance Program (EMP).

Why Cleaning Matters

Electrical equipment naturally attracts contaminants, dust, fibers, and sometimes even moisture. These limit cooling, accelerate wear, and create tracking paths that can lead to faults. Proper cleaning isn't just "wiping things down." It requires:

• Trained personnel familiar with approved cleaning materials and methods
• Care to avoid damage to insulation, windings, or protective coatings
• Awareness of which components should not be cleaned

Done correctly, cleaning extends the service life of equipment and reduces the risk of unplanned outages.

Why Torque Checks Are Critical

Connections loosen with thermal cycling and vibration. A loose bolt creates resistance, which generates heat, often invisible until failure. NFPA 70B requires torque verification using calibrated tools and manufacturer specifications. Key steps include:

• Verifying torque against published values
• Following limits (no more than 90% of the initial torque when rechecking existing hardware)
• Documenting each connection inspected

Infrared scanning and resistance testing often identify "suspect" connections, but torque verification is the hands-on step that ensures reliability.

The Champion Approach

When you enroll in a Champion Electric EMP, cleaning and torquing aren't optional add-ons, they're core services. Each program includes:

• Scheduled cleaning and debris removal tailored to equipment type
• Torque verification of bolted connections using calibrated tools
• Supporting tests such as infrared scanning and insulation resistance
• Clear documentation with prioritized recommendations

The Result

Reliable power, longer equipment life, fewer surprises, and compliance with NFPA 70B standards.

Preventive maintenance is about more than inspections; it's about correcting issues before they cost you downtime. Cleaning and torquing do exactly that.
