200-amp electrical panel replacement and service upgrade

Your electrical panel is the central heartbeat of your home or business. If your property still runs on an obsolete 60A or 100A fuse box, or an aging breaker panel (Federal Pioneer, Commander, Sylvania), adding a Level 2 EV charger, hot tub, or heat pump can overload your system. MB Électrique specializes in electrical service upgrades to modern 200-amp or 400-amp panels that provide safe, dependable power for decades to come.

We handle 100% of the project: electrical load calculations, RBQ compliance, full coordination with Hydro-Québec for power shutoff, and same-day service restoration. Serving Mascouche, Terrebonne, Laval, and the entire North Shore.

Safety, insurance compliance, and guaranteed capacity. A modern 200-amp electrical panel eliminates fire hazards caused by overloaded circuits, protects sensitive electronics with certified surge protection, and ensures full compliance required by home insurance providers.

Warning signs that indicate you need an electrical panel replacement

Several critical indicators demand an immediate panel upgrade:

• Fuse boxes & hazard-prone panels: 1960s–1970s fuse boxes and Federal Pioneer (Stab-Lok) or Sylvania panels are notorious for mechanical failure where breakers fail to trip under overload. Quebec insurance companies frequently refuse coverage or mandate replacement.
• Frequently tripping breakers, buzzing, or heat: Burning odors, warm panel covers, or humming breakers signal loose internal connections and active fire hazards.
• Adding high-power appliances: Installing a Level 2 EV charger (32A to 48A), heat pump, or hot tub almost always exceeds the safety threshold of a 100-amp panel.
• Damaged exterior service mast or meter base: A leaning roof mast or cracked weatherhead wire requires immediate rebuilding according to Hydro-Québec standards.

Hydro-Québec coordination and strict RBQ safety standards in a single day

Electrical panel replacement requires high-precision craftsmanship strictly governed by the Electrical Code and the RBQ. MB Électrique manages every stage:

1. Official Hydro-Québec scheduling: We schedule the exact morning disconnection window with Hydro-Québec line crews.
2. Installation of the new 200A panel: We dismantle the obsolete equipment, mount a top-tier panel (Square D QO or Siemens) with new breakers, rebuild the exterior service mast if necessary, and connect certified copper grounding to your main water service.
3. Same-day power restoration: Power is restored that afternoon (outage typically limited to 4 to 8 hours), and we issue the formal compliance certificate required by your insurance provider.

Frequently asked questions about electrical panel replacement

Upgrading to 200 amps is essential when adding high-draw modern equipment such as a Level 2 EV charger, hot tub, central heat pump, or radiant floor heating. A 100-amp panel lacks the safety headroom to run these appliances simultaneously without tripping the main breaker. A 200-amp service future-proofs your home for the next 25+ years.

Power interruption is carefully scheduled and typically lasts between 4 and 8 hours on the day of work. We coordinate early morning disconnection with Hydro-Québec and complete the installation by mid-afternoon so your heating, refrigeration, and lighting are fully restored before evening.

The cost generally ranges from $1,800 to $3,800 depending on project scope. An indoor panel replacement alone costs between $1,800 and $2,500, while a complete service entrance upgrade—including an exterior mast, meter base, and new copper ground—ranges from $2,800 to $3,800. We provide fixed-price quotes prior to starting work.

MB Électrique handles 100% of the administrative process. As a licensed CMEQ master electrician with an active RBQ license, we submit all work declarations, schedule the disconnection and reconnection directly with Hydro-Québec, and deliver the compliance certificate required by your home insurance provider.
