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
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
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.
