TUBE FOR ELECTRIC WIRE, RELAY SOCKET TERMINAL BASE, AND RECEIVING AND DISTRIBUTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To easily check a line number for an electric wire connected to a lower terminal on a stepped terminal block without removing the screw for the electric wire connected to the terminal thereabove.

SOLUTION: The line number tubes for electric wires applied to electric wires connected to lower terminals are made longer. The line number indicating portions where line numbers for identifying the kinds of electric wires are marked are provided in positions away from the terminals. Thus, the line numbers for these lower electric wires can be easily visually checked by moving their tubes to the left or right even if electric wires connected to upper terminals are installed overlapping them.
