Each of the conductors that enter the terminal house fromSpier Falls passes directly to a three-point, double-blade knife switchafter leaving the insulator just mentioned. One blade of this knifeswitch connects the incoming conductor with a bank of lightningarresters in the first story, and the other blade of this switch con-nects with one pole of an oil switch on the second floor.
