Circuit breakers are a form of electrical safety mechanism intended for guarding against short-circuit or overload degradation to an electrical system. Its primary purpose is to stop the current from flowing in order to safeguard machinery and reduce the possibility of a blaze. A circuit breaker can also be adjusted either manually or automatically in order to reestablish regular function, in contrast to fuses, which can only be utilized one time before having to be replaced. Differently, sized circuit breakers have become available, ranging from minor equipment that safeguards low-current connections or specific domestic appliances to huge breakers intended to safeguard high-voltage power lines powering an entire region.

Regulations around different types of circuit breakers can even differ from one region to another. For instance, those in Canada should ensure that their circuit breakers are approved by the CSA department. Additionally, the installation as well as replacement of circuit breakers is a matter to be handled strictly by professionals as per local regulations. Let’s understand which type of circuit breakers one can choose from and what separates them from each other.

Types of Circuit Breakers

When it comes to types of circuit breakers, there are three main types of circuit categories that are commonly used in Canada. However, there are many more kinds that are used across the world. Circuit breaker electrical systems can be classified as either Standard, GFCI (Ground Fault Circuit Interrupter), or AFCI (Arc fault circuit interrupters). Each and everyone functions in a particular position within the residence and can manage a range of ampere capacities. Generally speaking, the type of the pane will determine which breaker you select.

Standard Circuit Breakers:

Standard circuit breakers come in two main types: Single pole breakers and Double pole breakers.

1. Single pole breakers:

Based on the product brand, single pole circuit breakers are available in three different kinds: full size (1-inch wide), half size (1/2-inch wide), or twin/tandem (1-inch wide with two switches and controls two circuits). They take up a single space on the breaker board. Furthermore, they have a single hot wire and one neutral wire, which is used to provide 120V to a circuit and withstand 15 to 70 amperes. These types of circuit breakers are commonly used in certain small appliances like fans, hair dryers, hair curlers, air compressors, power tools, general and outdoor lighting solutions, and vacuum cleaners.

2. Double Pole breakers:

As opposed to single-pole circuit breakers, double-pole circuit breakers take up two different spaces on the main breaker board. They have two hot wires which split a single neutral wire in order to supply 120V/240V or 240V to a current. Additionally, double pole breakers have capacities ranging from 15 to 200 amperes and are necessary for extensive equipment like washers and other major appliances. Central air conditioners, electric dryers, as well as water heaters are some of the many appliances which benefit from this type of circuit breaker.

GFCI or Ground Fault Circuit Interrupters

GFCI or Ground Fault Circuit Interrupters are simple and straightforward circuit breakers. One can add GFCI security to an entire circuit system by putting one inside the main switchboard, also known as a breaker box. This breaker box in which the circuit system is protects the wiring as well as all of the electronics and gadgets linked to that circuit. Moisture-ridden places, such as restrooms, recreational areas, underground spaces, and garages, necessitate the use of GFCI-type circuit breakers. In workplaces as well as other locations wherever heavy equipment and power tools are being used or anticipated to be used. People who use these tools are advised to get the GFCI-type circuit breakers installed. As the breaker can potentially trip without your knowledge, GFCI safety is not advised for items that should operate constantly, such as refrigerators or hospital instruments.

AFCI or Arc fault circuit interrupter circuit breakers

AFCI or Arc fault circuit interrupter circuit breakers represent a variety of arc fault safety for low voltage circuit breakers. A powerful discharge across two separate or broken conductors is an arc fault. The heat generated by such arcs has always had the potential to ignite a blaze, seriously harm people, and endanger infrastructure. In the event that it detects an arc in the connected circuit, the AFCI shuts down the loop. It safeguards against a fire that could result from an inadvertent electrical discharge in the circuitry or a cable. The breaker immediately disengages the affected circuit after detecting the electrical leap and unusual path, stopping the arc before it can become hot enough to ignite. A possibly hazardous arc is differentiated from an innocuous arc that occurs naturally when connectors, switchgear, and brushed motors are operating.

When talking of the Canadian circuit-breaking installations, it has already been established that they need to be CSA-approved.

Additionally, other factors, such as the load type, region of operation, etc., will help determine which type of circuit breaker you may need. If you need clarification about which is the ideal type of circuit breaker for your needs, you can hire a professional to help you out.

It is essential to note that Canadian regulations make it a mandatory requirement that every circuit breaker be installed by professionals who have the appropriate licenses.

Getting them installed by oneself or by unlicensed professionals can land you in trouble. It must be remembered that these regulations are made for the safety of the citizens as well as to ensure that everyone gets the correct resolution for their problems.

Finding the correct type of circuit breaker is essential to ensure that you can enjoy an uninterrupted electrical connection that extends to every single household use.

It is also essential for ensuring that your home does not get set on fire. Having the correct type of circuitry installed in your space is mandatory for the inhabitants. Renters must also check out if the rented space is up to code when it comes to the circuitry. While getting new circuit breakers installed in your space, it is imperative that you check the relevant codes to make sure that your contractor is doing the job right.
