MWBCs

MWBCs, or Multi-Wire Branch Circuits, are electrical circuits that supply power to multiple outlets or devices. They are commonly used in residential and commercial settings to distribute electricity efficiently. An MWBC consists of two ungrounded (hot) conductors and a neutral conductor, with each hot conductor supplying power to separate circuits. This configuration allows for the use of two 120-volt circuits in a single 240-volt circuit, effectively doubling the available power.

MWBCs are typically used to power devices that do not require continuous power, such as lights, outlets, and small appliances. They are also used in situations where the load on a single circuit would exceed the circuit's capacity. However, it's important to note that MWBCs should not be used to power devices that require continuous power, such as refrigerators or air conditioners, as this can cause overheating and potential safety hazards.

MWBCs are installed by licensed electricians and must comply with local electrical codes and regulations. They are a cost-effective way to increase the number of outlets and circuits in a space, but they should be used with caution and proper installation to ensure safety and functionality.
