Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • GFCI tripping repeatedly without an obvious cause
  • Failed electrical inspection due to missing or damaged ground termination
  • Loose or corroded grounding connection at the control box
  • Visible damage or breakage on existing grounding lug
  • Intermittent electrical faults traced to a poor ground bond

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm the existing lug accepts a #8 AWG ground wire — this lug is rated for #8 single wire only
  • Verify this is an Allied Innovations OEM part number match for your specific control system
  • Inspect the mounting location on your equipment bond/ground bar to confirm the lug style and thread pattern match
  • Have a licensed electrician assess the full grounding circuit before replacing any grounding hardware
  • Check local electrical code requirements — some jurisdictions have specific grounding lug standards for spa installations

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
