Installing Bulletin 500LC Lighting Contactors

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˚ Cwire.All

power wires should enter enclosure adjacent to the 500LC

terminals. Combination knockouts are provided on Type 1

enclosures. L ine 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.

In st all over cu r r en t p r o t ect ive devices

for the contro l circuit in accordance

with app lic able electrical cod es.

Table D lists the maximum distances and minimum wire sizes that

can be run between a control station and one Bulletin 500LC.
