Section 210. 3 says
"Branch circuits recognized by this article shall be rated in accordance with the maximum permitted ampere rating or setting of the overcurrent device. The rating for other than individual branch circuits shall be 15, 20, 30, 40, and 50 amperes. Where conductors of higher ampacity are used for any reason, the ampere rating or setting of the specified overcurrent device shall determine the circuit rating."
Branch circuits serving only one device can have any rating, but when a circuit supplies more than one load it is limited to up to 50 amps. So does this mean you can't feed a panel from a circuit breaker in a panel?
