Are the 120vAC supply cables daisy-chained from fixture to fixture?

• A. Yes
• B. No
• C. Sometimes
• D. Only with adapters

Answer: (B)

Power to lighting fixtures should be distributed through proper branch-circuit wiring in accessible junction boxes, not by chaining the fixture’s own supply leads from one fixture to the next. The short supply cables that come with a fixture are designed to connect the fixture to the house wiring (or to a driver/transformer) and are not intended to serve as through- feeds for multiple fixtures. Using them to daisy-chain can overload those leads, create heat, and violate typical electrical codes. If a fixture is specifically designed to be chain-fed, it will provide designated through connections and instructions; otherwise, connect each fixture to the branch circuit through appropriate junction boxes and conductors.
