What We Do
As Connecticut’s leading mission-critical electrical contractor, C&H Electric specializes in the design, construction, and maintenance of critical electrical distribution systems.
This non-invasive method detects heat anomalies like loose connections, overloaded circuits, and insulation failures—helping prevent equipment damage, costly downtime, and electrical fires.
This service complements infrared imaging by detecting inaudible sound waves caused by corona, tracking, and arcing—helping identify failures in components like switchgear and transformers to prevent unplanned shutdowns.
C&H Electric analyzes voltage and current to detect issues like drops, distortion, or imbalances—protecting equipment and ensuring stable, safe power distribution.
Visual inspections catch wear, damage, or code issues early—helping prevent downtime, safety risks, and compliance violations.
Our switchgear maintenance includes cleaning, lubricating, and torquing components, along with contact resistance and insulation resistance testing — ensuring safe, efficient operation and preventing costly failures.
Breaker testing includes primary and secondary injection testing to verify performance and trip settings, along with thorough cleaning and lubrication to ensure reliable operation and extend equipment life.
Our transformer testing includes winding resistance and turns ratio analysis to verify electrical integrity, along with cleaning, lubricating, and torquing to ensure safe, efficient, and long-lasting performance.
We provide specialized healthcare electrical maintenance including line isolation monitor panel testing, critical receptacle verification, and customized service plans to support Joint Commission and AAAHC Environment of Care compliance.
We design electrical maintenance plans to meet insurance and OHSA requirements, minimizing risk and liability.
Our predictive and preventive maintenance and testing services protect against potential hazards.
We address deferred maintenance to restore optimal performance and extend the lifespan of electrical systems.
Our on-call maintenance teams are available 24/7 to provide immediate responses to urgent issues. They swiftly address problems to minimize downtime, maintain operational continuity, and prevent potential losses.
We upgrade outdated facilities to improve reliability and future-proof your operations.
Our comprehensive documentation ensures compliance and simplifies audit readiness.
We ensure that your electrical systems and safety procedures meet NFPA 70E standards.
Our energy solutions identify and resolve inefficiencies, optimizing performance and reducing costs.
Our predictive maintenance finds failing equipment prior to catastrophic failure, so we can support the equipment replacement cycle through our strong supplier relationships to ensure timely access to high-quality materials.
We prefabricate electrical devices at our production facility to ensure efficient installation, keep pace with rapid construction schedules, and reduce material handling and waste on the job site.
