1.Determine run length.

2.Order the appropriate number of JOINER FIXTURES for the complete run.

3.Order one POWER FEED END SET per run.

4.Order one SINGLE STEM or CABLE ASSEMBLY per JOINER FIXTURE.

5.For cable mounted runs that exceed amperage limits, order the appropriate number of CABLE/CORD FEEDS.

Square/Rectangle Patterns:

1.

Order appropriate number of JOINER FIXTURES to complete the pattern size.

2.
