P & M Electrical Contractors | Certified Electricians in Biddeford, ME

Our thorough electrical inspection identifies vulnerabilities in your home's wiring, grounding system, and main service panel that can leave appliances unprotected during common local power fluctuations. We check for proper surge protection and recommend upgrades, like whole-house surge suppressors, to shield your refrigerator, HVAC, and electronics from the damaging spikes that often occur in our area.

Generator transfer switch issues are a frequent problem here, often caused by corrosion from coastal air, faulty sensors, or improper installation. During our inspection, we test the entire transfer system—from the generator itself to the automatic transfer switch (ATS) and its connection to your main panel. We ensure it's properly sized, wired, and maintained so it seamlessly takes over when the grid power fails.

For homes with backup generators, our inspection goes beyond standard checks. We meticulously examine the transfer switch for safe operation, verify the generator's fuel line and battery connections (common failure points), and ensure the load calculation is correct for your home's needs. This proactive check is crucial in our community to prevent failure during a storm-related outage.
