Panel & Service Upgrade Compliance
The panel is where insurers, inspectors and home inspectors all look first. Sixty-amp services, fuse boxes, and certain problem breaker panels known for failure-to-trip trigger insurance conditions across Canada — and heat pumps and EV chargers are pushing even sound 100A services to their limits.
What triggers an upgrade requirement
Insurers commonly require replacement of 60-amp services and screw-in fuse panels as a condition of coverage. Certain older stab-type panels widely installed in Canadian homes have documented failure-to-trip histories and appear on many insurers’ refusal lists regardless of apparent condition. And load growth — EV charging, electric heating conversion, hot tubs, secondary suites — legitimately outgrows 100A in many homes, verifiable through a code load calculation rather than guesswork.
What a compliant upgrade involves
A licensed electrical contractor files the permit/notification, coordinates the utility disconnect-reconnect, replaces the panel or upgrades the service conductors and meter base, corrects grounding and bonding to current code, and the provincial authority or inspector signs off. That inspection record is the document your insurer wants — keep it permanently.
Load calculations for EVs and suites
Before assuming you need 200A, a Canadian Electrical Code load calculation often shows an EV charger fits on 100A with a load-management device — a fraction of a service upgrade’s cost. We arrange the calculation first so you only buy the upgrade you need.
How the process works
- Tell us what prompted this — insurer letter, EV charger, renovation, or a flagged panel brand.
- A licensed contractor confirms scope with a site visit or photos and a load calculation.
- Permit is filed; utility coordination booked.
- The upgrade is completed and authority-inspected.
- You receive the inspection certificate for your insurer and records.

Frequently asked questions
Is a fuse panel illegal?
No — but insurers dislike them because oversized fuses are easy to install, and most will require replacement to bind new coverage. Replacement also usually resolves the 60A service question at the same time.
How much is a 200A service upgrade?
Typically $3,000–$6,000 for a house depending on province, service type (overhead/underground) and mast/meter work. Panel-only swaps are less.
My panel brand is on an insurer list — do I have to replace it even if it works?
Practically, yes, if that insurer is your option: the concern is failure to trip under fault, which no visual inspection can rule out. Replacement cost is modest against a coverage refusal.
Do I lose power during the upgrade?
For several hours on the day, yes — the utility disconnects while the contractor works. It is nearly always a one-day job for a house.
