Electrical Spa Wiring Connection Instructions
WIRING CONNECTIONS
1. Identify the TB-1 terminal block located inside the GL2000 control box on the left side.
2. Connect the 8 AWG BLACK wire from the RCI 32AMP breaker , terminal L1 to TB-1, Line 1.
3. Connect the 8 AWG RED wire from the RCI 32AMP breaker, terminal N to TB-1, neutral.
4. Connect the 8 AWG GROUND wire from the RCI 32AMP breaker, terminal GND (ground) to
TB-1, ground.
5. At least two additional lugs marked “Bonding Lugs” are provided on the external surface of one
of the bonded components metal enclosures. To reduce the risk of electrical shock, connect the
local common bonding grid in the area of the hot tub or spa to these terminals with an insulated
or bare copper conductor not smaller than No. 6 AWG.
6. All field-installed metal components such as rail, ladders, drains or other similar hardware within
10 ft (3m) of the spa or hot tub shall be bonded to the equipment grounding bus with copper
conductors not smaller than No. 6 AWG.
7. Replace the control box cover and securely tighten the fastening screws. Close and secure the
equipment compartment panel.
Note
: Always use copper wire only (3 wire with ground. 8 gauge under 50ft, 6 gauge over 50ft)
The electrical supply for this product must include a suitable rated switch or circuit breaker to
open all ungrounded supply conductors to comply with Section 422.20 of the National Electrical
Code ANSI/NEPA 70-1987. The disconnecting means must be readily accessible to the tub
occupant but installed at least 5 feet (1.5m) from tub water.
Note: The RCI breaker must be placed in sight of the spa at a minimum distance of
five feet (1.5m) away.
Note: As of January 1, 1996 the National Electric Code (NEC) requires RCI on all
spa installations.
