A. ELECTRICAL JUNCTION BOX ASSEMBLY
1. Cut 11 pieces of PVC pipe, Schedule 40, electrical conduit, 1 1/2 inches (3.81 cm) long (1). After cutting,
remove all burrs, shavings, and dust. These 1 1/2 inches (3.81 cm) lengths of conduit will serve as connec-
tors between the junction boxes. 10 are for the for junction boxes, P/N E981DFN (2), and one is for the
last junction box, P/N E980DFN (3).
2. Glue two 1 1/2" pieces of conduit (1) in the end of each junction box, P/N E981DFN (2). Glue one 1 1/2"
piece of conduit (1), in the end of the last junction box, P/N E980DFN (3). This junction box is used as the
terminator for the curcuit.
3. Glue two female adapters, P/N E942D (4), on the end of the 1 1/2" conduit pieces (1). These serve as
mounting points for the compression nut connectors, used later.
