Not quite strictly true.As I see it. There is no requirement for a TT earthing arrangement as the pool is within the equipotential zone.
Why waste a perfectly good earth?
OK it's CE marked, however, it doesn't run on IEC voltages, it used NEC voltages?It is all ce marked equipment
It is all ce marked equipment
See your post #14 where you said it was 3 phase in and 3 phase out. Now explain to me how you are going to design a "centre tapped earth" 3 phase transformer. and explain to me how that differs from a star transformer...... or use a centre tapping to earth of the transformer. Would using the centre tapping be a good idea in which case the transformer could be specified with this tapping. If it's not worth doing this then it can be left off the spec.
Thanks to all your replies and sorry if it's a bit vague.
A very accurate analysis of the situation.You have two issues that are not connected.
1. How do you earth your installation.
Based on what you have said there appears to be no need for a TT Earth.
2. How do you install foreign equipment.
I will leave this to those better suited to answer.
I think he says it was in his house not his mothers on the other side of the fields!!just wire it in a long length of 1.5. volt drop will take care of the voltage issue
