Jacuzzi J-315 Manual page 35

8. Is the GFCI utilized at the main panel?
• Verify how it is hooked up.
• If you are not licensed to properly change the wiring, show the customer how it should be hooked up and
have them call the electrician. (Improper installation is not a warranty call which once corrected may involve
you coming back to replace a component.) If there is a problem with the electrician understanding the
correct hook up of the hot tub, have the electrician contact Jacuzzi Hot Tubs Technical Support.
9. Is the GFCI and wiring dedicated only to the hot tub?
10. Are there any other devices hooked up to the hot tub; a light, extra outlet, etc.?
11. How long is the run from the main panel to the hot tub?
• Longer runs require a wire size compatible to that length of the run.
12. Is there a disconnect or sub-panel in the run?
13. How is the disconnect hooked up? Be specific.
• There needs to be FOUR wires (two hots, a neutral, and a ground) at the disconnect for the GFCI to properly
function.
14. Is this a 3-wire or a 4-wire hook up from the breaker box to the spa?
• The J-325, J-335, J-345 are all 240 VAC, 3-wire hook ups.
• The J-315 is a 3-wire when hooked up to 120 VAC, and a 4-wire when hooked up to 240 VAC.
15. Is there 240 VAC (120 or 240 VAC on J-315) at the hot tub?
• Refer to the model the customer has purchased and then confirm the hook up using the diagrams provided
in sections A9-A10 on pages 50-51.
16. How are the wires connected at the GFCI?
• 3-wire, 240 VAC hook ups DO NOT USE A LOAD NEUTRAL OUT OF THE GFCI TO THE HOT
TUB.
17. Is the neutral wire hooked up on the GFCI output terminal?
• In a 240 VAC only hook up, this will cause the GFCI to trip.
18. Where is the neutral wire hooked up at the GFCI?
• The neutral "Pigtail" should go directly to the neutral bar.
19. Is the load neutral wire capped off or taped at the spa?
• This will cause the breaker to nuisance trip; the wires can act like an antenna and pick up stray or inductive
current or radio frequency interference.
