Section 210.4 covers multiwire branch circuits and states that each multiwire branch circuit must have a way to simultaneously disconnect both ungrounded “hot” conductors at the point where the circuit originates. What does this mean as far as the type of circuit breaker that would have to be used?
What will be an ideal response?
A multiwire branch circuit originates in a loadcenter so this means that a two-pole circuit breaker will need to be used instead of two single-pole circuit breakers.
