| Apparatus for selectively disconnecting the electric service of individual customers from an electric power supply line by electrical signals transmitted from a central point remote from the customer's premises. A circuit interrupter, such as a circuit breaker or, preferably, a fuse, is connected in series with the circuit of each of the customers, and is operated by a coded signal, transmitted from the central point by radio waves or over telephone or power lines, which is received by apparatus at the customer's premises and thereupon actuates the interrupter. Preferably, the coded signal is transmitted to the customer's premises using the same apparatus used to remotely read the customer's utility service meter, such being an Automatic Remote Meter Reading (ARMR) system of a known type which would also be installed. Also, novel remotely operable fuses which are particularly suited for use as the circuit interrupter in the system are described. | ||||||
