A pool is only non-conductive, if it is empty, with the plastic liner, however, once full of water, it takes on a new set of Regulations. We have very strict Codes Of Practice, for pools over here, regardless of type or size. Every authority we have here has an interest in swimming pools, and for God sakes do not ask about Spa pools

Bill and Paul, The reason why I asked not to ask about Spa pools, is because, we have a real can o'worms, being opened here,(at least on this side of the Pacific). You guys, may or may not know, how a Spa pool, works, assuming you do not, I will go on,(as both of you fella's are accustomed to), a Spa pool, uses a number of systems, including, a water pump circuit, to re- circulate the water in the pool, as it is heated, then there is an electrode- boiler, type arrangement, that heats the water, obviously via a Contactor. But, there are also a large number of safety systems involved, with these pools. For a start, there are interlocks, if the water pump fails, the system shuts down. Also, the electrode-boiler circuit, is fed through an RCD (GFCI), there is also an interlock on the Control circuit, that if, this breaks, the whole pool shuts down. But, it is not the Operational safety of these pools, it is the Regulatory safety, of the equipment used, you can test this gear till you are Blue in the face. We now have a whole new breed of Spa pools that plug into the wall socket, these have to be certifyed as to complying with AS/NZS 3000, and most of the time, these Pools are not even fed through an RCD, this is my one complaint (compliant?!) Your thoughts on all of this. (Feel free to edit this message)

The bureaucratic regulatory monster rears it sugly head again, eh?
I'm not sure I like the idea of using electrode water-heating on a spa pool. O.K. ,you can include all sorts of safety interlocks and so forth, but there's just something about the arrangement that makes me think "No thanks."

What I meant about the "can of worms", was with the fact that most of the Spa pools that I have ever seen, have been illegally plumbed in, some even leaking underneath, because the wrong type of PVC solvent was used, you can normally blame the owner for this. This, in turn causes the owners to complain that the wiring was done incorrectly, as the over-temperature cut-out trips all the time, through lack of water in the pump circuit.:mad
