Synchronous transfer control system in an arc resistant enclosure

A synchronous transfer control system for controlling operation of a number of electric motors, comprising:

• an arc resistant enclosure having a main housing having an open top portion and an arc plenum fluidly coupled to the top portion, the arc plenum having a closed front portion, a closed rear portion, and at least one open side portion structured for direct or indirect connection to a duct or vent system, the main housing having a number of enclosure members each made of a material having arc resistant ratings of 50 kA -0.5 s, Type 2B;
• a plurality of synchronous transfer control components housed within the main housing, the synchronous transfer control components including:
• (i) a hard bussed first bus structured to be coupled to a first power source, (ii) a second power source, and (iii) a hard bussed second bus, wherein an output of the second power source is able to be selectively coupled to the second bus, wherein the first bus is able to be selectively and individually coupled to each of the motors, and wherein the second bus is able to be selectively and individually coupled to each of the motors.
