    Re: bonding /grounding question

    Grounding and bonding are different. Grounding rods are for grounding, but not for bonding. The pump should be grounded to the electrical ground. The pump should be bonded to the pool and everything else made of metal (that isn't tiny) within three feet of the pool.

    The rules for above ground pools vary a little bit from place to place. Some areas consider above ground pools to be temporary, even if they are large, others count them as permanent above some size. The details of exactly what you need to do vary depending on which way that goes.

    To expound on that, grounding is about providing an electrical path to ground. Bonding is making sure all the metal objects in a structure (or within a certain proximity) are at the same potential.

    So, let's say a current carrying wire in your electric pump somehow makes contact to the metal housing of the pump. You're trying to figure out why your pump isn't running, so you grab it while you are standing in a puddle of water. You get zapped. Unless of course the pump was grounded back at the main panel providing an easier path to ground than through your body & the puddle of water.

    In most cases, if an electrical circuit goes to ground, it should trip the breaker in your service panel, but it is very possible that it won't. So in this case, let's say the same wire breaks lose in your pump, there is no puddle of water, you touch the pump, you don't get shocked. You lay your other hand on electric heater next to your pump, and because the length of wire going back to the service panel is longer, or thicker, or the connection is corroded a little bit, you get shocked because there is a difference of potential between the two appliances, and you provide a parallel path for the electric current.

    Re: bonding /grounding question

    As I said, the rules vary from place to place. I don't know if you have to have bonding where you are.

    If you need to be bonded: No grounding rod at all. The green ground wire from the pump should run back to the electrical ground in the electrical panel. A separate #8 bare solid copper wire needs to run from the bonding connector on the pump, all the way around the pool. If the frame of the pool is metal it must be connected to that #8 copper in a couple of places. That isn't usually the top rail, normally it would be towards the bottom of a leg/supporting brace. The details vary depending on how your pool is made.

    If you have the metal frame Intex, I'd bond the frame and pump even if it isn't required in you locale. Just a bare #8 wire attached to one of the legs will bond the entire pool.
