While these panels have a long lifespan, outdated or inadequately sized panels can lead to diminished efficiency and the risk of system overloads.

Upgrading your electrical panel has a wide range of cost as every home’s electrical load can be unique. For example upgrading an electrical panel from 100-amp to 200-amps can range between $1,300-$3,000 or more.

Fig 1. is an example of an electrical panel that requires updating. For example, there should not be any wire nuts (the orange cap covers) within a panel.

What are the signs my electrical panel needs an upgrade?

Visual warnings can include signs of internal deterioration, such as rust/cracking along with the presence of multiple wires on a single fuse terminal. Similarly, if you are frequently experiencing blown fuses or tripped circuit breakers.

Older homes can also have outdated panels which pose a safety risk. The most common obsolete panels in Ontario are:

• Fuse panels
• Federal Pioneer – were recalled in 2007 by the ESA (Click Here to read the ESA article). Fig 1. is also an example of this brand of recalled panel.

What is the best size of electrical panel for your home?

The expense associated with upgrading your electrical panel is predominantly influenced by the required amperage, commonly referred as “electrical load”. There are online tools for homeowners to figure out this estimate themselves. If you are looking for a more precise measurement, a certified electrician can provide this service.

Is it necessary to upgrade to a 200-amp panel?

A 100-amp panel service is often well-suited to efficiently manage the electrical requirements of an average-sized home, supporting essential appliances and lighting circuits. Especially in Ontario, where other sources of power such as natural gas power larger appliances, unlike places like Newfoundland that do not have a natural gas source available for customers.

Often a 200-amp panel will be suggested if a renovation requires higher electrical demands such as electric vehicle chargers, hot tubs,  or  extensive home office equipment (i.e. network infrastructure) to name a few. Similarly, an upgrade will often be recommended for larger residential properties or commercial buildings that may have multiple appliances, heating and cooling systems running simultaneously.

Upgrading to a 200 amp-panel will also ensure that your home is future-proofed for the next renovation and ensures a great safety margin by reducing circuit overloads and breaker trips!
