Frequently Asked Questions

My AFCI breaker keeps tripping in my Marblehead home. What's usually the cause?

Arc-fault circuit interrupters (AFCIs) are safety devices that trip when they detect dangerous electrical arcs, which are a common fire hazard. In our coastal area, a frequent culprit is rodent activity—mice and squirrels can chew through wire insulation, creating arcs. Other causes can include loose connections in outlets or switches, or damaged cords. As a licensed electrician, I can safely diagnose the source of the trip, whether it's in an outlet, a switch, or within the wiring itself, and provide a reliable repair to restore safety and function to your circuit.

I'm considering an EV charger installation. What does that process involve?

Installing an Electric Vehicle charging station starts with a site evaluation of your home's electrical system. We need to ensure your main panel has the capacity for the new circuit, which often requires a 240-volt dedicated line. For many older homes in Marblehead, this may involve a panel upgrade or service increase. I handle the entire process: from obtaining any necessary permits, running the proper gauge wiring in conduit, installing the outdoor-rated charger unit, to the final inspection. The goal is a safe, code-compliant installation that provides convenient charging for your vehicle.

As a one-person operation, how do you handle larger electrical projects?

While M.J.L Licensed Electrician is my own business, I've built a network of trusted professionals over my ten years in the trade. For larger projects like a full panel replacement or a whole-home rewire, I manage the project from start to finish and bring in licensed, skilled help as needed to ensure the work is completed efficiently and to the highest standard. This approach allows me to maintain direct oversight and communication with you, the homeowner, while ensuring the job has the right resources. You get the personal attention of a local owner with the capability to tackle significant electrical work.
