I'm planning to install a new circuit to support a NEMA 14-50 outlet, but I'm not clear on what circuit breaker to use. I have a GE panel that uses half-size circuit breakers, (GE Q-Line). I want the circuit to handle 50 amps at 240v. I plan to use a 2-pole breaker, but I'm confused about the amp rating. This is what the breaker looks like on the Lowes website. It's two 25 amp breakers tied together. It says it supports 50 amps, but I'm suspicious. It might be 50 amps if it were two 120v circuits, but only 25 amps at 240v. I'm confused.
