Document Type and Number:
Japanese Patent JP3037356
Kind Code:
B2
Abstract:
PURPOSE:To detect a breaker connection line in an active state only by an operator on a load side by a method wherein a startup signal of a main tester is sent from the load side to a distribution line to be connector to the load, the side of a distribution board sends a response signal indicating a line number to the load side and the response signal is received on the load side to have the line number displayed. CONSTITUTION:A main tester 9 is connected to a distribution line 3a on a side of a load 4a to send a startup signal to the distribution line 3a. When a line detection circuit sends a line number signal to an information send-out circuit 7, the information send-out circuit 7 receives particular information according to the line number signal from an address information setter 6 and sends it as a response signal to the distribution line 3a. The load 4a side receives the response signal on the main tester 9 and displays it in characters on a display unit 9a.
