An automatic isolation switch (AIS) system is provided for controlling a supply of electrical power to a load. The system includes a switch and a controller. The switch is connected between a first power system and the load and between the first power system and a second power system. The first power system includes a grid, and the second power system includes a power source and an inverter coupled to the power source. The controller is configured to detect an adverse power condition on the first power system for supplying electrical power to the load; to isolate, via at least one switch, the first power system from the load and the second power system, in response to the detecting of the adverse power condition; and to activate the inverter of the second power system to supply electrical power from the second power system to the load.

A troubleshooting compartment for a motor control center unit, provides electrical access to test control points inside the motor control center unit, without exposing the operator to electrical hazards from the main line-voltage components inside the motor control center unit. The troubleshooting compartment comprises an accessible compartment contained within a motor control center unit, which is separate from a main line-voltage compartment of the motor control center unit, the accessible compartment having an access side to enable operator access to the accessible compartment without need to open the main line-voltage compartment; an accessible compartment door covering the access side of the accessible compartment from a front side of the motor control center unit; and feed-through terminals mounted within the accessible compartment, for test points and pilot devices operating at low, control voltages.
