What is a double pole 30 amp breaker? Many homeowners and electrical contractors are familiar with the term “double pole” when it comes to circuit breakers, but what exactly does it mean? A double pole breaker is a type of breaker that occupies two slots in the electrical panel and has two hot wires connected to it. It is often used for larger, more powerful appliances or circuits that require more than one breaker. In this article, we'll look at what a double pole 30 amp breaker is, why it's important, and how to correctly install it.
A double pole 30 amp breaker, also known as a two-pole breaker, is the largest type of residential circuit breaker available. It combines two single pole breakers into a single unit, taking up the space of two separate breakers. The double pole breaker is rated for 30A and is usually found in the main service panel, as well as in subpanels. It is designed to protect high-powered circuits that draw more than 15 amps of power. For example, it is the standard breaker size for 240 volt air conditioning, large water heaters, and electric stoves.
The double pole 30 amp breaker is actually quite simple. It uses two breakers housed in a single unit, with each breaker controlling one of the two hot wires. When either side trips, both sides of the breaker disconnect from the line, cutting off all power to the circuit. This provides added protection from overloading the circuit and potential hazards such as fires.
