Tell the office what happens and when so a diagnostic visit can be discussed. These symptoms do not establish a need for a new panel or larger service. Do not open electrical covers or repeatedly reset a breaker. For smoke or an active fire, leave the area and call 911.
Age alone does not establish wiring type, condition or a need to rewire. Two-prong outlets also do not prove knob-and-tube wiring. An assessment identifies the existing installation, any concerns and the work appropriate for the property and project.
Boston Inspectional Services handles electrical permits and inspections. We confirm requirements for the agreed scope. Exterior changes in a designated historic district may also need City review.
Start with the parking arrangement, cable route, electrical capacity and required owner or association authorization. Massachusetts has specific rules for qualifying EV charging requests; the property and proposed work still need review. Compatible load management may be considered where the equipment and installation support it.
No. Panel replacement and increasing electrical service capacity are separate decisions. Equipment condition, existing demand and planned loads guide the recommendation. A renovation, heat pump or EV charger does not automatically require 200 amps or a larger service.
