Situation: 42" storable pool, 125 V motor, 3 wire cord connected to a GFIC receptacle (no dedicated) and no bonding at ladder, frame etc ... good, no problem.
But, why a ground rod - no bonded to the grounding electrode system (isolated) bonded to the motor lug? It doesn't make sense to me!
I don't think this rod is necessary but can be any problem with this?
Please any sugestions.

Esthy-- a ground rod is not necessary unless you have fed a panel at the pool area. In that case you must have an electrode for the separate structure. If this is a storage pool then you only need wire the pump. Also read art. 680 Part III for recp. locations etc.
 
I didn't install it, a general contractor did. I was there to replace a damaged receptacle and saw it, of course it confused me. But I think the rod been there won't do any harm .... will do any harm?

What is the ground rod connected too?

One more question about this storage pool. The customer installed a canopy - fabric with metal frame - over this pool, the metal legs (6) are resting close to the edge. Does that frame needs bonding? Sorry but I don't do pools and this situation leave me thinking! BTW this pool is resting over dirty not concrete.
 
Now I am thinking. If this motor is "permanentely" connected to the rod and the pool has a big canopy over, I don't think the customer will ever storage this pool
 
The ground rod being connected to the bonding lug on the pump motor will not cause a problem.

Because this is a storable pool the bonding requirements of Part II of 680 don't apply. Take a look at Part III of 680 for the requirements for storable pools.

Here is the definition. It does not matter whether they take it down or not

Storable Swimming, Wading, or Immersion Pool. Those that are constructed on or above the ground and are capable of holding water to a maximum depth of 1.0 m (42 in.), or a pool with nonmetallic, molded polymeric walls or inflatable fabric walls regardless of dimension.

I think that if this pool meets the definition of a "storable swimming pool" then regarndless of whether or not they intend to store it or not it only needs to meet the requirements of Part III of 680.

I agree with Chris and Dennis.
 
The customer allowed me to go back and take pictures. I will correct the situation. (btw, this is the second pool in this month unsafe wired. Here are the pictures:

Spliced cord to timer and timer to a living room, middle run 20 amps receptacle (changed to a GFIC). Note 14 AWG from the receptacle to timer. Motor: 115 V / 12.0 Amps. This is a permanent installation.

Flex, calling out to Flex, here is a good example of where it MAY be fine for you to rave. It'd be in third party fashion. This WASN'T ESTHY's install. Do you still feel like venting? I'll let you have first dibs:grin:
 
Pool pump motors with lugs are listed for permanent pools only.

Pool pump motors for storable pools do not come listed with lugs. The pump will have a cord that is 25 feet in length, as part of the UL Standard for these types of pumps.

Pumps (WCSX)






Pumps investigated for permanently installed pools are so identified and are additionally marked ??Do Not Use With Storable Pools?? . Permanently installed pool pumps are intended to be permanently connected to the water circulation system and they may be permanently wired or provided with a 3 ft nondetachable power supply cord terminating in a grounding type attachment plug. The attachment plug may be of the locking or nonlocking type. Units provided with locking type attachment plugs are​


intended to be installed at least 5 ft from the inside walls of the pool and are marked accordingly. Units provided with a nonlocking type attachment plug are intended to be installed at least 10 ft from inside walls of the pool and are marked accordingly. Permanently installed pool pumps are provided with an accessible pressure wire connector for equipotential bonding. ​


Pumps investigated for storable pools are so identified and are additionally marked ??Do Not Use With Permanently Installed Pools?? . Storable pool pumps are intended to be connected to a water circulation system constructed so that the pump may be readily disassembled from the system for storage and future reassembly to its original integrity. Storable pool pumps are provided with a minimum 25 ft non detachable power supply cord terminating in a grounding type attachment plug, are double insulated, have no accessible grounded metal parts, have inaccessible non current-carrying metal parts connected to the grounding conductor of the supply cord and do not have an equipotential bonding connector. These pumps may be provided with integral filters.​
