Note
Through-type terminals with sectionalizing feature allow easy isolation
of the current path without disconnection of conductors. The sockets
of the terminal screws allow actions, such as the measuring of the
loop resistance or connection of an ammeter to the circuit. The use of
connection combs reduces the conductor cross-section by one level.
