WebbReduces wiring costs and installation time by enabling contractors to use multi-wire branch circuits, commonly known as "shared neutrals". When using single pole CAFCIs, a dedicated neutral is required for each circuit. It allows electricians to share neutrals between the two circuits fed by the breaker. WebbA shared neutral circuit has an additional hot conductor, which is connected to the opposing phase. This allows a further 20 amps to be delivered, with the addition of only one conductor. There will be 240V between the two hot conductors, and 120V between either hot and neutral.
