Preventative Electrical Maintenance in Massachusetts and Vermont

We capture and record true RMS voltage and current readings across your system to confirm the correct levels are present for your equipment to operate properly and reach its full service life. Deviations point to underlying issues that need attention before they cause damage.

We measure and record voltage drop across components including circuit breakers and contact surfaces. Excessive voltage drop indicates components that are no longer performing correctly, which creates both equipment risk and safety hazards.

Using thermal imaging equipment calibrated to NFPA 70B recommendations, we identify and document elevated temperatures caused by high-resistance connections, current overload, defective breakers, and failing insulation. Infrared scanning catches developing failures that are completely invisible during a standard visual inspection, reducing the risk of brownouts, blackouts, and fire hazards.

We measure and record ultrasonic activity above the audible range to detect corona, tracking, and arcing conditions within your electrical system. Ultrasonic testing works alongside infrared scanning to give a more complete picture of system integrity, catching failure modes that neither method would identify on its own.

We capture Total Harmonic Distortion readings for both voltage and current and compare them against IEEE recommendations. Harmonic contamination outside acceptable tolerance levels can damage microelectronic equipment, transformers, breakers, and motors, and can affect the accuracy of your power charges. Early identification keeps those risks in check.

We test to confirm the phases in your electrical system are properly balanced. Unbalanced phases drive power quality problems, increase total harmonic distortion, and raise operating temperatures in devices and current-carrying conductors, all of which shorten equipment life.

With your system live, we inspect the interior and exterior of all accessible components, checking for corrosion, rust, discoloration, leaks, physical damage, grounding issues, and applicable code violations. Adjustments are made where necessary to keep performance within specified limits.

We measure and record insulation resistance under conditions specified by the manufacturer or NFPA 70B. Insulation values that have deteriorated below acceptable levels are a leading indicator of catastrophic failure risk, including fires and explosions. Catching them early keeps that risk off the table.

We measure, record, and compare winding resistance values against manufacturer specifications. Deviations indicate components that are drifting out of tolerance, compromising both performance and service life before any outward sign of failure is present.

We measure the resistance between contact surfaces within your electrical components. Poor contact surfaces drive increased voltage drop and heat buildup, which accelerates deterioration and raises the risk of brownouts, blackouts, and equipment failure.

We measure, test, record, and document findings for all applicable low voltage circuit breakers. A breaker that has never been tested under load may fail to trip when it needs to, or trip incorrectly at the wrong moment. Regular testing confirms your protective equipment will perform its intended function.

We measure and record the resistance of conductors, connections, and grounding devices throughout your system. A grounding system that isn't performing correctly offers no protection during a fault, and the problem is rarely visible without testing.

We measure, record, and monitor transformer condition against manufacturer recommendations and NFPA 70B standards. Transformer failure carries serious consequences, including fire risk and extended operational shutdown. Staying ahead of it through regular testing is significantly less costly than responding to it after the fact.

We measure, record, and monitor motor condition against manufacturer recommendations and NFPA 70B standards. Motors operating in demanding environments accumulate wear that trending data makes predictable. Catching a motor approaching failure gives you time to plan replacement on your terms.

With components de-energized, we conduct a thorough inspection of interior and exterior conditions, including corrosion, rust, discoloration, leaks, physical damage, grounding, safety hazards, and code compliance. Adjustments are made where needed to bring performance back within specified limits.

We verify appropriate anchorage, required area clearances, absence of physical damage, and correct alignment across your electrical system components.

All active components are exercised where applicable, including breakers, disconnects, and contactors. Components that sit dormant can seize or fail to operate correctly when called upon.

De-energized equipment receives a thorough interior and exterior cleaning, including vacuuming and blowing out as required. Energized equipment receives exterior cleaning using appropriate safety procedures. Contaminated equipment runs hot and fails early.

Minor issues are addressed on the spot during the visit, at no additional charge. Missing knockouts, loose hardware, and similar items don't wait for a follow-up call.

After every visit, you receive a written report covering what was inspected, what was found, and what actions are recommended. Across visits, we compare results to identify trends that indicate a system moving toward failure, giving you the lead time to plan rather than react.

Electrical systems change over time, and documentation rarely keeps pace automatically. Our technicians make notations and updates to existing one-line drawings as field conditions change, keeping your records accurate.

When a covered component fails, we repair or replace it, including all labor and materials, with no additional charges.
