A multi-wire branch circuit is two or more circuits that is served by a a set of hot wires connected to different phases (all with the same voltage between them) and a common neutral wire (all of the hots also have the same voltage with respect to the neutral).Click to see full answer. In this regard, what is a multi wire circuit?A Multiwire Branch Circuit (in the electrical code) is defined as a branch circuit that consists of two or more ungrounded conductors (two or more “hot” wires) that have a voltage between them (they are not on the same electrical phase and so are connected to different buses in the electrical panel), and a groundedLikewise, what is 3 wire used for? Three-conductor wire can be used to power a single circuit that would otherwise require two 2-wire circuits. For example, the black might feed a line of receptacles, while the red feeds a line of recessed light fixtures in the same area. Additionally, can multiple circuits share a neutral? A shared neutral is a connection in which a plurality of circuits use the same neutral connection. In a 3-phase system it is legal in some jurisdictions to share a single neutral wire between all three (3) phases. One neutral may not have two “hot” wires from the same phase.How does a multiwire branch circuit work?According to NEC Article 100, a multiwire branch circuit consists of two or more ungrounded conductors that have a voltage between them, and a grounded conductor that has equal voltage between it and each ungrounded conductor of the circuit and that is connected to the neutral or grounded conductor of the system.
