Specification
The time switch shall be of the 24-Hour dial type, capable of permitting up to 12 ON/OFF operations each day. The time
switch shall provide a minimum ON/OFF time of 1 hour. The time switch shall be powered by ____________ (125)(208-
277) VAC,_________ (50)(60) Hz power supply. The time switch motor shall be a synchronous motor, which shall be
designed to withstand a minimum of 6000 volt transients. The time switch motor shall be connected to the supply
terminals with ring-type connectors and shall not require more than 3 Watts to operate the time switch. The time switch
mechanism shall be a snap-in design to provide ease of mechanism removal from the enclosure. The time switch
enclosure shall be a _______________(Type 1 steel)(Type 3R steel)(Type 3R plastic with see through cover) lockable
enclosure. The time switch enclosure shall provide a minimum of 31 cubic inches of wiring space and provide a non-
removable cover, which shall swing open a full 180 degrees. The time switch shall provide clear terminal identication on
a see-through non-curling terminal insulator. A visual indicator shall be provided in the time switch for inspecting clock
motor operation. The time switch contact blades shall be a one piece design with welded silver alloy contacts and shall
be designed to provide wiping action on contacts during operation to ensure reliable load switching. Terminal
connections shall be made using teeter-type terminal screws to provide secure connections for wire sizes up to #8 AWG.
