What is the proper way of bonding swimming pool,like fence,ladder,diving board.Its been a while since i did one.Ive used #6 solid copper to bond metal apuratus in and around pools,but i forget if i ran this wire back to panel or just started at the ground lug of a grounded pump motor.I also used copper crimps where needed.What type of lugs should i use to bond ladder,fence and etc....please help

If it has been awhile since you last did this, you would be well off to visit Article 680 of the NEC. There have been numerous changes in this article over the years.

You do not have to connect the pool bonding grid to the panel.

Use approved lugs and crimps (or clamps) for connecting all the required locations to the bonding grid.

Be sure to use connectors, Lugs etc that are approved for Direct Burial. Yes, bond the wire mesh.

Most of what has been said sounds OK, but I just want to add that as far as "bonding" and "grounding" in regards to the pump motor, please do not confuse the two. The motor is required to be grounded with an minimum #12, insulated, installed per 680-25(2)(c), that is, within conduit, or as specified. Bonding of the motor is achieved by the connection of a #8, solid copper conductor, per 680-22(b), and connected to the pool bonding grid. I recently inspected a pool installation where the label on the pump motor said that "grounding" is to be done with a minimum #8 conductor. I called the contractor on it, they went back to the manufacturer who in turn wrote me a letter that stated that they had mislabeled their own product and that they meant that the #8 conductor was to be used for "bonding", not "grounding", and they apologized for the confusion that their labeling may have caused.
If you really want to see some eyes glaze over, try explaining bonding and grounding to an owner-builder of a swimming pool, especially when it comes to the requirements of each at the light niche, as grounding is required in two ways and bonding in another, for a total of three grounding or bonding methods!
(My reference is the 1996 NEC, as that is what we are still enforcing in California)
