Before you buy — quick checklist

  • Confirm you have #8 AWG ground wires — this bar is rated for #8 gauge connections
  • Count the number of grounding conductors in your panel to confirm 5 positions are sufficient
  • Verify the MA-30 physically fits your existing Allied Innovations control box or enclosure
  • Check that your local electrical code accepts this style of grounding bar for spa applications
  • Inspect existing ground bar for corrosion or damaged lugs before assuming a direct swap

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