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.
Manufacturing & Industrial Projects
Predictive Maintenance
Aerospace & Defense Manufacturer — East Hartford, CT
During a scheduled infrared scan at an active aerospace manufacturing facility, C&H technicians detected a failing circuit breaker feeding a main bus duct — actively melting insulation. Left undetected, the failure would have shut down all production for 3–4 weeks at $2,500/hr. The issue was corrected before any failure occurred.
Electrical Contracting
Rich Products Corporation (Carvel)
Upgraded a live food production facility from 12M to 19M annual units — including a 500ft rooftop conduit run, overnight 2,500A switchboard expansion (6 to 9 sections), and full refrigeration + HVAC power integration. Zero production downtime.
Electrical Contracting
Nutmeg Bakery (329 Dunkin' Locations)
Fast-tracked 16-month buildout of an 80,000 sq. ft. commercial bakery — installing 3× 500kW backup generators with full-building ATS, 1,000A solar provisions, and coordinating power for Moline and White Industries production equipment across a continuously evolving scope.
