This specification covers electrical crimp-style lug terminals and conductor splices used for electrical cable connections.
Crimp-style lug terminals and conductor splices shall be of the following types, as specified (see 6.2.1):

Type CCBC - Splices, conductor, cable connector, butt-crimp. Type CCPC - Splices, conductor, cable connector, parallel-crimp. Type CLC  Terminals, lug, cable, crimp. Type CLCG Terminals, lug, cable, crimp with water-seal insulation grip. Type WTG  Terminals, lug, wire, with water-seal insulation grip.

Intended Use: Type CCBC conductor splices are primarily intended to permanently splice two cables. Conductor splices are intended to permanently splice two cables, or tap off a cable run, or ground equipment onto a ring buss. For shipboard use, conductor splices are intended to connect the conductors of the grounding system in wood ships. Type CLC terminals are intended for use wherever the standard solderless type lug terminals are used, and also for those applications where the operating temperatures are normally higher than is permissible for such solder-type lugs. Use with flexible cable may necessitate using the next larger size lug, for a given circular mil area because of the larger outside diameter of the flexible conductors. Type CLCG terminals are intended for use where water sealing of cables is specified. Type WTG wire terminals are intended for use in the same manner as cable terminals except that they should be used on the smaller wire or cable sizes where cable sealing is specified.
