As standard equipment, the enclosure includes timer, on-off switch, motor starters for each system motor complete with fuses and thermal overloads, signal lights, transformer to operate the 110V control circuit, capacitors to brake the motor, capacitor relay and terminal block. A clear plastic cover is mounted over the timer and on - off switch. This can be locked or sealed by the inspection agency.
