An electrical schematic for an elevator disconnect shows line voltage entering through fuses, a transformer stepping down to one hundred twenty volts, and a shunt trip operator tied to auxiliary contacts and a mechanical interlock. Fuses protect the line and load sides with specific ratings for four hundred eighty or two hundred eight to two hundred forty volt configurations. Optional components include a pilot light, a fire alarm voltage monitoring relay, and a key test switch. General notes require coordination with elevator shop drawings for horsepower size and proper disconnect placement near the door with required code clearances.
