# What is the difference between a single-pole breaker and a double-pole breaker?

The difference between a single pole breaker and a double pole breaker is the amount of hot wires and the amount of voltage each one can handle. A single pole breaker has one hot wire which is black and supplies 120V to the circuit. A double pole breaker supplies 240V to its circuit and has two hot wires which are usually a black wire and a red wire.
