Abstract
A field convertible tap-off base for an electrical busway distribution fitting. The field convertible tap-off base includes an AC phase termination side and a field configurable side having first and second configurable electrical terminals. The AC phase termination side provides terminals for connecting three AC phase conductors of a busway electrical distribution system to any one of a number of load bases configured for electrical components such as circuit breakers, switches, fuses, lugs or other special functions. The first and second configurable terminals permit two additional busway electrical conductors to be used for neutral, high current capacity neutral, secondary ground, DC current or other special functions which might be defined in the busway electrical distribution system.
