Single Pole vs Double Pole Breakers: Which One Should You Choose?

Single Pole vs Double Pole Breakers: Which One Should You Choose?

It goes without saying that electrical safety is crucial whether it’s your home or your workplace. You’ll have to invest in a quality circuit breaker that can deal with electric overloads and short circuits in order to protect you and your property. Now, most of the first-time buyers often get confused between a single pole vs double pole breaker. It’s a tricky decision especially if you don’t have enough know-how about both the types and their uses. If you are stuck in a similar situation then this is just the right place for you. 

Today we are going to jot down the key differences between both the breaker types, how they work and when is each required. Stick along to make a better and a more cost effective decision! 

Understanding A Single Pole Breaker 

A single pole breaker is most commonly used in residential electric panels specifically for light applications and circuits. It connects to one neutral wire and one hot wire. Considering the fact that it provides 120 volts electricity and an amperage between 15amps to 20amps, it’s perfect for everyday power uses in homes. Not only does a single pole breaker provide complete protection, in fact, it’s more economical and easy to install as well. 

Understanding A Double Pole Breaker

Double pole breaker applications include all heavy-duty appliances that require more power and more protection. From dryers to water heaters and ovens, a double pole breaker provides just the right protection you need. This breaker connects to two hot wires and it’s the main difference between 1 pole vs 2 pole breaker. You should also opt for this breaker type of electric vehicle chargers and other air conditioning units etc as it comes with an amperage between 20 amps to 60 amps and provides around 240 volts of electricity.

How To Choose Between A Single Pole Vs Double Pole Breaker?

Now that you know about the difference between single pole and double pole breakers, deciding which one to use will be much easier for you. If you are still stuck with which breaker should I choose? then here’s what can help; 

Use a single-pole breaker when; 

  • You are wiring basic home circuits

  • The appliances don’t require much power 

  • The load lies between 15amps to 20amps

Use a double-pole breaker when; 

  • The applications require more than 240V of current 

  • You want to protect heavy appliances like an air conditioner, oven or an EV charger

  • Your circuit requires high amperage that lies between 20amps to 60amps

Important Safety Considerations When Choosing A Circuit Breaker 

Make Sure To Hire A Professional For The Installation: If you aren’t sure about DIY circuit breaker installation, it’s best to hire a licensed electrician for it. Installing a breaker means you’ll have to work inside the electric panel, and even a single mistake can become dangerous for you. It’s best to work with a professional for proper installation. 

National Electrical Code: Different circuits have different breaker requirements, and it is of utmost importance to first check if you meet the National Electrical Code safety standards before proceeding with the installation. 

Extra Safety With Double Pole Breakers: Double pole breakers connect to two hot wires and both trip at the same time in case of an overload or short circuit. In a nutshell, it immediately cuts off the power supply, which is quite crucial for safety. 

Final Takeaway 

Single pole breaker uses include all the light applications and outlets that aren’t power-hungry. In simpler words, it’s the best option for home owners because these circuits do provide the kind of electric protection you need for your day to day power appliances. On the other hand, a double pole breaker is mandatory for heavy and power-hungry appliances like HVACs and water heaters etc.

When it comes to the single pole vs double pole breaker cost, the latter is more expensive because it provides extra safety to heavier appliances. In general, both the breaker types are quite effective in their own respective applications. They both offer unique advantages just as per your electrical requirements. You just have to make a decision based on your usage!
