How do I ground a 24 ft above ground pool?

The equipment - pump etc - should have a ground connector with the wiring if it is the plug in type. If the equp. is to be hardwired then a separate green wire should be pulled into the conduit from the source to the pump etc. In addition to that all the equipment should be bonded electrically. Your electrician will know what this means. By connecting this green wire as per code you should be Ok. However, this is a job for a qualified electrician who knows the codes in your area. As for connecting the metal walls of the pool - I do not know what the code calls for in your state for grounding or bonding this piece.
