Publication 500LC–IN001A–EN–P May 2005
Line and load terminals are reversible. The Bulletin 500LC
Lighting Contactor is UL Listed for use with 60 or 75˚ C wire. All
power wires should enter enclosure adjacent to the 500LC
terminals. Combination knockouts are provided on Type 1
enclosures. Line and load connections are supplied with clamp
type terminals. These terminals accept the wire sizes #18–10
AWG Cu. Insert appropriate line and load wires and tighten clamp
screws to 18 inch–pounds.
Control Line Connections
Control circuit connections designated L, O, C on the right side are
supplied with clamp type terminals. These terminals accept wire
sizes #18–10 AWG Cu. Simply insert appropriate control wires
and tighten terminal clamp screws to 18 inch–pounds. See the
wiring diagrams.
Install overcurrent protective devices
for the control circuit in accordance
with applicable electrical codes.
Table D lists the maximum distances and minimum wire sizes that
can be run between a control station and one Bulletin 500LC.
Table D – Control Line Run
