Electric Panel Installation for Portland Properties

Casco Bay Electric is a fully licensed electrical contractor with offices in Portland, Lewiston, Arundel, and York, running 100 to 130 jobs per week across Southern Maine and New Hampshire. The company serves everyone from individual homeowners to major general contractors and institutional clients, with master electricians overseeing all work.

Electrical panel installation is a core part of our work. From upgrading a 1910-era Portland home with an outdated 100-amp service to increasing capacity in a Bayside commercial building, every installation is designed around the property's electrical demands. Our focus is simple: properly sized, code-compliant electrical systems built for safe, reliable performance.

Types of Electric Panel Installation We Provide

Residential Panel Installation

Residential panel installation in Portland most often involves upgrading an older 100-amp service to a modern 200-amp panel, a necessary step for homes adding EV chargers, high-draw appliances, or additional circuits from a remodel. Portland's Victorian-era and early 20th-century homes frequently carry outdated equipment that no longer meets current load demands. Our electricians pull the required permits, coordinate with the utility, and complete the installation cleanly. For homeowners adding a finished basement, a new kitchen, or an EV charging station, proper panel sizing is the foundation of the project.

Commercial Panel Installation

Commercial buildings in Portland require panel work that accounts for multi-tenant load calculations, three-phase service, and phased construction timelines. We work directly with general contractors and building owners on office buildouts, hospitality renovations, and institutional facilities, including schools and hotels where reliability and code compliance are non-negotiable. Our team is equipped to handle switchgear, subpanels, and service entrance upgrades on projects of any scale, and we take on last-minute contracts when other contractors can't mobilize fast enough.

Industrial Panel Installation

Industrial panel installation involves higher-voltage services, motor load calculations, and coordination with utility providers. Casco Bay Electric has hands-on experience with utility and manufacturing environments — including active accounts at a plastics plant and Unitil substation work — giving our team familiarity with the demands industrial customers place on electrical infrastructure. We own our equipment, including bucket trucks and specialized testing gear, so there are no subcontractors or scheduling gaps between project phases.

Why Portland Chooses Casco Bay Electric

Licensed at Every Level

All work is performed under master electrician supervision, with journeyman electricians handling field installations. We are fully licensed in Maine and carry the credentials required for commercial, industrial, and residential permits.

Real People Answer the Phone

Fully staffed local offices with a live estimator mean that when a GC or homeowner calls, someone picks up and can actually move on the job.

Built for Last-Minute Mobilization

Builders and contractors working against tight schedules rely on us specifically because we can step into a project on short notice. We structure our operations to stay flexible for exactly these situations.

Volume Builds Competence

Handling 100 to 130 jobs per week across multiple trades means our crews have seen the full range of what Portland's building stock presents. That volume translates directly into faster diagnosis, fewer surprises, and cleaner installs.

Full Equipment In-House

Excavators, bucket trucks, thermal imaging cameras, and underground fault locators — all owned, not rented or subcontracted. When a panel installation involves underground service entrance work or infrared inspection, we handle it without delay.

24/7 Emergency Availability

Our rotating on-call electricians provide 24-hour emergency service every day of the year. When a panel failure takes down a hotel, a school, or a residential building, response time matters.

Local Portland Presence and Service Area

Casco Bay Electric's Portland office at 322 Presumpscot St puts the team close to every part of the city, from the dense residential neighborhoods of Munjoy Hill and the West End to the commercial and industrial activity in Bayside and along the waterfront. We have worked extensively in Portland's older housing corridors, where knob-and-tube wiring, undersized services, and aging panels are routine inspection findings. That familiarity with local building stock means fewer surprises mid-job.

Our electricians operate from a van-based dispatch model, extending effective reach well beyond the Portland office itself. We are actively working in new construction alongside major GCs, in hospitality properties near the Old Port, and in institutional facilities throughout Greater Southern Maine.
