I don't do many pools but a good customer wants us to wire one.

Fiberglass premolded pool with 3 foot concrete apron.
Pool installer said bonding not required. I think that any rebar or reinforcing metal must be. Yes? No?

Also we have a pool pump 240 volt hard wired and a salt generator ???
again 240 volt hard wired. I was thinking of running small 3r sub panel out to the equipment area and branch to the equipment from there.
Anything wrong with this installation? Also does any of this equipment need to be gfci priotected. Again I don't normally do pools.
Thanks

I've seen one to completion yet, but I stayed at a Holiday Inn Express recently.

Yes, see NEC 2005 680.26(C):
...The equipotential common bonding grid shall extend under paved walking surfaces for 1 m (3 ft) horizontally beyond the inside walls of the pool...

I don't believe that the 240V pump by code has to be GFCI protected if hard wired. The manufacturer instructions may call for it. On a voluntary basis, I can't see how it could hurt.
 
You can answer how-to questions if the person posting the question is qualified to do the work - i.e. they are an electrician, an engineer, or some other professional involved in electrical work. (Use your own judgement for that last catagory).

But if someone asks how to install a wirenut, I would take the 5th.

Edit: Also, more specific questions are more likely to get answers than general ones. If the original poster (OP) asked "What do I need to know to install a pool.", then "680" would be a good answer. Also, "Here is how I would do this - does it sound alright?" is more likely to get a specific answer than "How do I do this?".

On another note, if it sounds like the OP doesn't have a code book, or they are just too lazy to read it, a lot of people give answers like "Article 680". I don't think that is the case with this thread.

I thought the rule was "We don't answer questions of a how to nature".
Yes or NO?

I think that half of the stuff on here is of the "how to" nature. As Steve said, it's who's doing the asking that counts.

Make sure to read 680.25 and look real close to 680.25(B) for this subpanel you mentioned.

Do you twist the wires, before you put the nut on, or not??

Speaking of twisting the wires...... When you twist, do you twist just the bare part? Or do you twist the rest of the wire thats in the box? I twist till the insulated part makes about 1 round. I have many times (especially ballasts, which I usually have to work live) that are twisted about 6 inches! That makes things get kinda hairy!

The instructions for one brand of wirenut says you are to twist until approximately two twists are visible in the wire that remains outside of the wirenut. The same instructions also says, "pretwisting acceptable, but not required".
