Three types of electrical panels in Canada

In this article, we want to examine the types of electrical panels. So stay with us until the end of the article.

There are three main types of old electrical panels in Canada:

Single-phase electrical panels

These electrical panels are the type that most homes have today. It has two 120-volt circuits (or “legs”) and a ground wire.

A single-phase system draws all power from one outlet at a time, so it cannot be used for anything that requires more than 240 volts, such as a clothes dryer or air conditioner.

Three-phase electrical panels

Among the types of electrical panels, three-phase electrical panels can be mentioned, which are usually found in multi-family buildings such as apartments and condominiums because they allow more electricity from one source to be delivered to several units without the need for copper wires and cables. to be given.

Three-phase electrical panels

As much as one unit. Phase systems do. They are also used in industrial environments where heavy machinery requires large amounts of power, such as manufacturing plants or construction sites.

Four-wire electrical panels

This type of electrical panels is mostly used in rural areas where few people live near the village or where there is no electrical infrastructure such as transformers or substations needed to effectively distribute electricity to long distance consumers.

All kinds of old brands of electrical panels

  • Friedrich
  • General Electric (GE)
  • Westinghouse
  • Hammond
  • Chromelux
  • Square D

In this part of the article, we will introduce three famous brands of electrical panels, Square D, Advance and Cutler Hammer.

All kinds of old brands of electrical panels

These types of electrical panel brands have been around for years and are famous for producing quality and long-lasting products. They also offer a variety of different styles and sizes to suit different needs, so you can choose the best option for your home or office.

Brands and types of electrical panels are very different. The most common ones are Advance, Square D and Cutler Hammer.


Advance is a brand of Schneider Electric, a global leader in energy management. Schneider Electric is one of the largest suppliers of electrical distribution equipment in the world to the industrial and commercial markets.

Square D

Square D is a brand of Schneider Electric, which also owns the other brands on this list. The company was founded in 1887 by William H. Merritt as the Merritt Electric Manufacturing Company.

In 1961, it merged with Square D Corporation to form Square D Corporation (SDC). SDC was acquired by Schneider Electric in 1999 for $4 billion and became its North American subsidiary.


Cutler-Hammer was founded in 1912 by Henry Cutler and Carl Hammer as the Cutler-Hammer Manufacturing Company. It has since been acquired by Cooper Industries, which sold its electrical products division (including Cutler-Hammer) to Eaton in 2012 for $2.9 billion.

Upgrading all types of old electrical panels in Canada

The Canadian Electrical Code requires that all switchboards have a current rating of at least 100 amps. This is because the maximum load on each circuit depends on the number of appliances connected to it, as well as their wattage.

For example, a 15 amp circuit can only handle 15 amp appliances, even if they are all only 1 amp. The maximum load in a 20 amp circuit is 20 amps and so on.

Most homes built before 1965 have 100 amp service panels. A minimum upgrade to these buildings would be to replace them with a 200 amp service panel and all new wiring from the panel to the breaker box.

However, if your home’s electrical system can handle more than 100 amps without problems, this may not be necessary. The best way to determine if your home needs an upgrade is to have a complete electrical inspection done by an experienced professional who knows how older buildings work.

Upgrading all types of old electrical panels in Canada

Upgrading electrical panels is an important part of home improvement. It’s a big project that can be daunting, but it’s a must-do if you have old wiring or even if you’re just looking for better energy efficiency and safety.

Here’s what you need to know about upgrading your old switchboards in Canada:

There are two main types of electrical panels: single phase and three phase. Their difference is in the way electricity is distributed throughout the house. Single phase panels use two wires while three phase panels use four wires (three hot wires and one neutral wire).

Single-phase panels are commonly found in older homes because they were used before three-phase became popular in Canada in the 1960s and 70s.

The cost of upgrading all types of old electrical panels

The average cost of upgrading an old switchboard is between $1,500 and $2,000. This includes the cost of labor and materials needed to install a new panel and connect it to the old wiring system.
