200-Amp Panel Upgrade
Toronto & GTA
Remove the infrastructure bottleneck holding your home back. Upgrade from an outdated 60A or 100A panel to a modern 200-amp service and unlock the full potential of EV charging, battery storage, and modern appliances.
The Bottleneck Problem
Most GTA homes built before 2000 were wired with 100-amp or even 60-amp service. That was enough for the era, but modern electrical demands have outpaced these aging panels.
The Problem: Capacity Overload
A 100-amp panel cannot safely support the simultaneous demands of modern living:
- Tesla Wall Connector draws 48 amps at full power
- Tesla Powerwall 3 requires a dedicated 40-amp breaker
- Modern heat pump HVAC systems need 30-50 amps
- Induction range or electric oven uses 40-50 amps
That is 158-188 amps of demand on a 100-amp service. The math simply does not work.
The Solution: 200-Amp Service
A 200-amp panel provides the headroom needed for today's electrical demands and tomorrow's upgrades:
- Full-speed EV charging without compromise
- Powerwall integration for whole-home backup
- Room for future electrification (heat pump, induction cooking)
- Modern breaker protection with arc-fault capability
200 amps of capacity provides a safe, code-compliant foundation for modern all-electric living.
What's Included: Turnkey Scope
Every panel upgrade is a complete, end-to-end service. No hidden costs, no surprise extras. Here is exactly what we deliver.
Utility Coordination
We handle all communication with Toronto Hydro, Alectra, or Hydro One for power disconnect/reconnect scheduling. No calls or paperwork for you.
Existing Panel Removal
Safe removal of your existing panel and meter base, including proper disposal of outdated equipment and any hazardous materials.
New 200A Panel Installation
Installation of a new 200-amp rated panel with copper bus bars, providing maximum conductivity, durability, and code-compliant circuit capacity.
Whole-Home Surge Protection
A dedicated surge protection device is installed to guard your entire home's electronics, appliances, and sensitive equipment from voltage spikes.
Circuit Re-termination
Every existing circuit in your home is carefully re-terminated in the new panel with proper torque specifications, labelling, and organization.
ESA Inspection Certificate
We file with the Electrical Safety Authority, coordinate the inspection visit, and ensure you receive your official ESA certificate of inspection.
Installation Timeline
A typical panel upgrade takes 1-2 days of on-site work. Here is the step-by-step process from assessment to completion.
Site Assessment & Load Calculation
We visit your home, assess your existing panel, calculate your current and future electrical loads, and provide a detailed scope of work.
Day 1 (30–60 minutes)Utility Coordination & Permits
We schedule the power disconnect with your utility provider, file ESA notifications, and confirm all permits are in place.
1–3 weeks (handled by our team)Panel Installation Day
Our licensed electricians remove the old panel, install the new 200A panel with surge protection, and re-terminate all circuits. Power is restored same day.
1 day on-site (6–10 hours)Testing & Meter Base (If Required)
Complete circuit testing, meter base replacement if needed, and utility reconnection verification. All circuits confirmed operational.
Same day or Day 2 (2–4 hours)ESA Inspection & Handoff
The ESA inspector reviews the completed work. Once approved, you receive your inspection certificate and your panel is ready for EV charger or Powerwall installation.
Within 1–2 weeks of completionWhen You Need a Panel Upgrade
Not sure if your panel is the bottleneck? Here are the most common signs that a 200-amp upgrade is necessary.
Breakers Trip Frequently
If breakers trip when running multiple appliances, your panel is at or over capacity.
Planning an EV Charger
A Tesla Wall Connector requires a 60A breaker (48A continuous). Most 100A panels cannot accommodate this.
Planning a Powerwall
Tesla Powerwall 3 integration often requires panel upgrades for proper backup circuit configuration.
Aluminum Wiring Concerns
Homes with aluminum wiring benefit from a panel upgrade that includes proper AL/CU rated terminations and updated connections.
Fuse Panel Still Installed
If your home still uses a fuse box, it is outdated, potentially unsafe, and incompatible with modern electrical demands.
Major Renovation Planned
Kitchen remodel with induction range, basement finishing, or additions all demand more electrical capacity than older panels provide.
Frequently Asked Questions
Common questions about 200-amp panel upgrades in the Toronto and GTA area.
How long does a 200-amp panel upgrade take?
Most 200-amp panel upgrades are completed in 1-2 days of on-site work. The total project timeline, including utility coordination and ESA inspection scheduling, is typically 2-4 weeks from start to finish. We handle all the scheduling so you only need to be home on installation day.
Do I need a panel upgrade for a Tesla Wall Connector?
Not always, but many older homes with 60A or 100A panels do not have enough spare capacity to safely add a 48A EV charger circuit. We perform a load calculation during our free assessment to determine if your existing panel can handle the additional demand or if an upgrade is required.
Will I lose power during the panel upgrade?
Yes, there will be a temporary power outage during the switchover, typically lasting 4-8 hours on the main installation day. We coordinate with your utility provider (Toronto Hydro, Alectra, or Hydro One) to schedule the disconnect and reconnect efficiently. We recommend planning accordingly for perishable food and any medical equipment that requires power.
What is included in the ESA inspection?
The Electrical Safety Authority (ESA) inspection verifies that all electrical work meets the Ontario Electrical Safety Code. This includes checking proper panel installation, circuit terminations, grounding, bonding, and surge protection. We handle all filing and coordinate the inspector visit on your behalf. The cost of the ESA inspection is included in our quoted price.
Can I upgrade from a fuse panel directly to 200 amps?
Yes. We regularly replace old fuse panels (60A or 100A) with modern 200-amp breaker panels. This is one of the most common upgrade paths we perform and eliminates the limitations and safety concerns associated with aging fuse-based systems. The process is the same as any panel upgrade and includes new meter base installation if required by your utility.
