I recently installed a Ameerican Standard Whirlpool tub, that has a
2.1HP pump that came wired with a three prong plug. I also installed a EZ inline hearer that also came with a three prong plug. I put each of these on separate circuits (20A/15A pump/heater), isolated, ending with a GFCI-protected outlet. I was reading through the installation instructions for the heater, and it talked about "BONDING" the heater to the house ground supply.
I have done a bit of research, and now understand that that means a 8AWG bare or green ground wire needs to go to the heater and pump (although the pump installation instructions didn't say anything about this) and then to my panel.
OK I am gonna do this, but I was wondering how big a deal is this, in the meantime? Should I not use the hot tub due to danger? Both devices are grounded, and plugged into functional GFCI outlets. I (sort of) understand that the bonding ensures equal something-or-other ( no voltage differences) between each of the metal componets near the tub. thx
