What are Non-Shunted Sockets
Non-shunted sockets are sockets that feature individual entry points for wires, allowing for two separate tracks for the electrical current to flow. Unlike shunted sockets, which have internally connected contacts, non-shunted sockets do not have continuity between the contacts. This means that each contact requires its own power lead.
Non-shunted sockets accommodate the specific requirements of certain lighting systems, such as direct-wire LED lamps. These lamps operate directly from the line voltage and do not rely on a ballast to produce a high start-up voltage like fluorescent lamps. To ensure proper functionality, direct-wire LED lamps need to bypass or remove the ballast, and non-shunted sockets facilitate this by providing separate power leads for each contact.

Select the correct type of socket for linear fluorescent or LED light fixtures to avoid potential issues. Using the wrong socket can lead to premature lamp failure, electrical shortages, fire hazards, and may even void the UL listing or warranty on the lamp. Therefore, it is recommended to determine the appropriate socket type based on the specific lighting system requirements, with non-shunted sockets being suitable for direct-wire LED lamps and certain other applications.
