Overview
Switchgear is the backbone of your electrical distribution system—controlling, protecting, and isolating critical components essential for smooth operations. Without regular preventive maintenance, even the historically dependable switchgear can fail unexpectedly, leading to costly downtime, equipment damage, and safety risks for personnel.
At C&H Electric, we provide expert Switchgear Maintenance Services for key facilities across Connecticut. Our team follows NFPA 70B best practices to deliver comprehensive maintenance that enhances equipment reliability, safety, and performance. With our preventive maintenance approach, we help you minimize risks and avoid costly surprises.
Why Switchgear Maintenance Matters
- Prevents unplanned outages and system downtime
- Extends the operating life of electrical equipment and critical infrastructure
- Ensures compliance with NFPA 70B, OSHA, and industry safety standards
- Detects early warning signs of equipment degradation before failures occur
- Reduces the risk of electrical fires, arc flash incidents, and equipment damage
- Supports uninterrupted operations in critical environments like healthcare, manufacturing, and data centers
Regular maintenance isn’t optional—it’s essential for ensuring long-term operational success, safety, and code compliance.
Our Switchgear Maintenance Services
Cleaning, Lubricating, and Torquing
- Thoroughly remove dust, dirt, moisture, and other contaminants that could compromise system performance.
- Lubricate moving parts such as operating mechanisms and hinges to reduce friction and mechanical wear.
- Re-torque all critical electrical connections to manufacturer-recommended specifications to eliminate risks of loose connections and arcing.
Contact Resistance Testing
- Perform advanced testing to measure resistance across electrical contacts.
- Identify high-resistance joints caused by corrosion, looseness, or surface degradation.
- Ensure efficient current flow, reduce heat buildup, and prevent potential failures in your switchgear connections.
Insulation Resistance Testing
- Conduct insulation resistance (megohmmeter) testing to assess the health of internal insulation systems.
- Detect early signs of moisture intrusion, contamination, or insulation breakdown.
- Preserve dielectric integrity and prevent catastrophic equipment faults or downtime.

Our Process
We follow a proven workflow tailored to healthcare environments:
1. System Evaluation
- Conduct a thorough review of your switchgear's current condition, including historical maintenance records.
2. Visual Inspection
- Inspect for physical signs of wear such as discoloration, corrosion, and the equipment's operating environment.
3. Testing
- Perform both Contact Resistance Testing and Insulation Resistance Testing using calibrated instruments.
4. Mechanical Servicing
- Execute cleaning, lubricating, and torquing procedures to restore optimal mechanical and electrical conditions.
5. Reporting
- Provide detailed reports highlighting test results, identified issues, recommended corrective actions, and maintenance schedules.
