I'm going to estimate my first swimming pool job. I've been reading about swimming pool bonding and I've seen the term "exothermic weld" several times. I'm concerned that special welding may be required to bond rebar or other metal surfaces to the solid 8 AWG bonding wire.

Can I complete all swimming pool bonding with connectors and clamps or will welding be required?

If no welding required, are specialized clamps and connectors typically available at electric supply houses or will I be ordering over the internet. The link is one site that offers specialized swimming pool fittings.

Exothermic welding or "Cat welding" isn't difficult at all and kinda fun to do the first few times. I'm sure you can pick up the kit at your SH. Just a mold, some gun powder and a lighting tool. You just light it and it basically melts your grounding conductor to your grounding electrode.

Pouring the powder in, remember that the real spark power is on the bottom
of the container!!! Very Important!!! You can trickle out that powder to the
opening. Use leather gloves!

PS Notice that the pic only shows Copper and the Caddy book shows
Structural rod.

There's many moulds that can be purchased, it's not as one size fits all and they are not cheap!

I agree with BarJack

Any split bolt or clamp listed for direct burial should be fine.

Use direct burial clamps where ever you can. Meticulous preparation is necessary for a GOOD quality Cadweld. Anyone can do a Cadweld. Not everyone does the correct preparation of the conductors and welded materials.

I know a guy who put the powder into the mode without first inserting the metal disc and all just ran down the copper cable. Well...I didn't know him personally...I don't think. AND, I don't really think that he looked a lot like me as some of the others said. I don't trust them.

...who Caldwell's pools, its not a requirement of the NEC? Don't forget the potting compound for the ground wire for the underwater light, because inspectors will definitely look for it

..go to this link and look at the seven pics from article 680 , but note it is from the '05 NEC

I didn't think that there was such a thing as non-conductive steel. Maybe steel that has a non-conductive coating.
