Accessory distribution box. "There are two supply connections to this box from the main distribution box, one from each side of the ammeter. The box provides for the connection of accessories, duly protected by fuses in the box, in such a manner that the currents taken by these may be included in or excluded from the ammeter indications as is expedient. An earthing terminal is also provided for the return current connection of accessories."..... for the purpose". If electrical apparatus................ for the purpose". Starter Circuits. "The circuits........................... ................................ in operation. The circuits are clearly shown in the wiring diagram. The motor is of the sliding armature type. Pressing of the push button switch closes two contacts, one of which at once causes an exciting or "teaser" current to flow..................... ......... relay circuit which closed the main switch and cuttingoff the main current supply to the armature.
