provided for each motor on the chemical feed system. Running lights shall be
provided for each motor. All switches, lights and other electrical components
shall be NEMA4. All electrical devices shall be wired in conduit to the control
panel.

systems using control signals for electric stroke length adjustment:
Signal wiring for milliamp or voltage follower signals shall
not be run in the same conduit and shall not be terminated
in the same enclosure box as power and motor control
wiring.)
