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)
