Palm Lugs, Narrow Palm Lugs or Extended Palm Lugs, are just as their name suggests. They are lugs with an extended or narrow palm that are used to connect electrical cables to their source of electricity.
The Narrow Palm lug is generally used when terminating cables into low voltage, moulded case circuit breakers, where limited width terminal blocks causes problems for standard lug terminals. The compressed palm of the narrow palm lug provides an effective and efficient termination.
