Electrical Panel Upgrade: When Do You Actually Need One?

The honest answer: most 200A panels are fine

A 200A panel installed in the last 30 years is generally adequate for a typical home. The pressure to upgrade often comes from people trying to sell you something. Before spending $2,000–$4,000 on a panel upgrade, it's worth understanding whether you actually need one.

That said, there are clear situations where a panel upgrade is genuinely necessary — and putting it off creates real risk.

Situations where a panel upgrade is necessary

Your panel is 100A: Homes built before 1990 often have 100A service. This becomes a bottleneck when you add an EV charger, heat pump, or electric dryer. If your home already has AC and electric cooking, a 100A panel is likely already at capacity most of the time.

Your breakers trip regularly with normal use: A panel at capacity will show consistent tripping on the same circuits. If you trip a breaker more than once a month on a specific circuit and the load hasn't changed, the panel — or that breaker — may be failing.

You have a Zinsco or Federal Pacific panel: These specific brands have well-documented failure rates in their breaker mechanisms. Breakers can fail to trip under overload conditions, which means the panel's primary safety function is unreliable. If you have one of these, replacement isn't optional.

You're doing a major renovation or addition: Adding a home office, finishing the basement with its own circuits, or adding central AC all increase electrical demand significantly.

What a panel upgrade involves

A panel upgrade means replacing the entire breaker panel — not just adding breakers. The process involves: disconnecting power (Hydro-Québec must disconnect and reconnect the service), removing the old panel, installing and wiring the new one, obtaining the required permit and inspection, and scheduling the Hydro-Québec reconnection.

From first call to reconnection, the job takes one day. The Hydro-Québec appointment schedule adds 1–3 days on top of that.

What about adding circuits without upgrading?

If your panel has capacity but just doesn't have open slots, a tandem breaker or subpanel is sometimes the right answer. We'll tell you upfront which scenario applies to your situation rather than defaulting to the most expensive option.
