Jodi,

That breaker is not designed for two conductors.

If a breaker is designed for two conductors, it will say so on the label. The only ones I've seen are Square D Type QO. It will say 1 or 2. There will be pressure plates at the terminal that sandwich a conductor on either side, in a slot.

Gotta disagree with Tim here. For quite some time (maybe always), all Cutler Hammer type CH breakers, both single and double pole, up to 30-amps are listed by the manufacturer for one 8-14 AWG Al/Cu conductor or two 10-14 AWG Cu only conductors. It's not on that label in the photo. It's embossed on the side of the breaker. See photo.

Not sure how long it's been but it's definitely not always. I have one here on my desk, 20amp. single pole that does not have that listing on the casing or label. The terminal is different then the one you have pictured, looks like the one Jodi has pictured where the wire goes under the screw head, therein lies the difference, the one Jodi has is not rated for two conductors. I know I've had this breaker for at least ten, maybe 15 years. Not sure when the change took place.
