The Jiffy NicheTM housing is equipped with a combination bonding/grounding connector. The outside connection is the bonding connector as required by Article 680-22 of the NEC.
Bond the Jiffy NicheTM to the pool structure. Using a solid copper conductor size #8 AWG or larger, connect the bonding connector to all of the metal parts of the swimming pool, spa, or hot tub; and to all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5m) of the inside walls of the swimming pool, spa, or hot tub.
Bonding connects all metal parts within and around the swimming pool, spa, or hot tub with a continuous wire. Bonding reduces the risk of a current passing between bonded metal objects, which could potentially cause electrical shock if grounded or shorted. Reference the NEC codes for all wiring standards including, but not limited to, grounding, bonding, and general wiring procedures.
14. The inside connection is the grounding connector as required by Article 680-20(b) of the NEC. The NEC requires that where a non-metallic conduit is used, a #8 AWG insulated copper conductor be installed in this conduit. Pull this conductor into the niche housing at least 6-8 inches.
15. Insert the ground conductor through the small hole in the cord seal. To do this, you must first pierce the small hole all the way through the cord seal with a small Philips screwdriver, or similar tool (Fig.4). From the conduit, the ground conductor must be fed through the cord seal from the small to the large end of the taper.
16. Connect the ground conductor to the niche grounding connector. The connector and wire termination must be encapsulated in 3M Inc. Scotch Cast Wet Niche Potting Compound No. 2135 (UL File E130394) or equivalent, to protect the connection from the possible deterioration effects of pool water.
