Most modern homes are served by either 100 or 200 amp panels, with 200 amp increasingly becoming the standard recommendation for new construction and major upgrades. The right number for your specific home depends on its size, appliances, and heating system, not a single fixed rule. Here is how to think about it, from the licensed electricians at EZSMART, serving Toronto and the GTA.
These are general guidelines, not a substitute for an actual load calculation performed by a licensed electrician.
An undersized panel does not just risk inconvenience, it can lead to an overloaded system straining under regular use, more frequent breaker trips, and in some cases, safety concerns from a panel working beyond its intended capacity. On the other end, deliberately oversizing without a real need adds unnecessary cost. A proper load calculation, performed by a licensed electrician, is the most reliable way to land on the right number for your specific home.
Is 100 amp panel considered outdated now?
Not necessarily outdated, but many electricians now recommend at least 150 to 200 amp for new work to provide headroom for modern and future electrical needs.
How do I find out what amperage my current panel is?
The amperage is usually printed on the main breaker inside the panel, and a licensed electrician can confirm this along with its overall condition.
Does a bigger home always need more amps?
Generally yes, though it depends more specifically on appliance load and heating type than square footage alone.
Should I upgrade my amperage before or after a major renovation?
It is usually more efficient to address panel capacity before a major renovation, since new circuits and appliances added during the project can be planned around the correct capacity from the start.
