SpaMaybe

Never owned a tub but my significant other is really into them and I will enjoy it too. Two deals are starring at me today. 2007 Maxx Elite 6000 - like new from small dealer - he just brought it in from an older couple. $3200 delivered - warranty left is 2 years 2007(or 2006) Marquis 630 - Like new from private owner - $2500 but no delivery - warranty left may be 2 years only on shell/frame - local dealer is nearby Deal or no deal?

A metal underground water pipe is typically used for a residential Grounding Electrode NEC250.52(A)(1) but it must have a Supplementary Grounding Electrode which can be a metal rod in the earth. Both the metal underground water pipe ground electrode and the metal rod ground electrode are bonded with the service neutral only at the service entrance NEC 250.24(A) and no where else on the customer side NEC 250.24(A)(5). A gas pipe is not permitted as a Ground Electrode NEC250.52 but must be bonded to the grounding system NEC250.104, usually at the residential service panel. The gas pipe is being grounded rather than the gas pipe being the ground. "...earth shall not be considered an effective ground-fault current path." NEC250.4(A)(5) In a ground-fault condition, the current flows back to the service panel on the equipment ground wire where equipment ground meets the neutral conductor. The service neutral then returns the current safely back to the source (transformer in most cases) on a low impedance path. If a separate ground rod is used alone at the spa, there is no bonded low impedance path back to the source transformer which is potentially dangerous. However, a supplementary ground electrode (metal rod) is permitted to be connected to the equipment grounding conductors but the earth shall not be used as an effective ground-fault current path. NEC250.54. So install the spa ground rod if you like and connect it to the equipment but the service panel equipment ground wire must also be connected to the equipment.

Be Very Careful. Only do this work if you are qualified. The neutral conductor (it is a current conductor and not an equipment ground) is only bonded (permanently electrically connected) to the ground system at the service entrance, usually your main breaker panel. NEC 250.24(A) Do not connect the neutral to the equipment ground anywhere else. NEC 250.24(A)(5) It sounds like your breaker enclosure was configured as the service entrance main disconnect for your mobile home with the neutral bonded to ground but... Isolate the Neutral Assembly from ground by removing the bonding connector. Torque correct fasteners. Field Install the Equipment Grounding Bar, part number PK-O-GTA-2. Torque correct fasteners. Install a suitable breaker (Amp Rating and AIC Rating). Torque correct fasteners.
