The ce directive states electrical equipment.it does not say it must be a certain voltage. The Low Voltage directive has been in place since 1973 and was amended 1/97. This directive applies to all electrical equipment designed for use with a voltage rating between 50 and 1000V AC and between...

I know the buck stops with me at the end of the day. I keep getting diffrent opinions on what is right and wrong. Some people have said I can use the main incoming earth. Others are saying it must be turned into a TT or use a centre tapping to earth of the transformer. Would using the centre...

Sorry I know your having to guess the installation. The pool is situated by an outside wall for future access if things need removing. The earth rod could be located just outside. What are your thoughts on using a centre tapping for earth.

I read it, that it says that it needs an earth rod or mat. The next question which the regs doesn't mention is because I have to use a transformer could I use use the centre tapping of the transformer for an earth instead of an earth rod or mat.

The pool is to be situated in doors. The supply is a pme. The transformer will be fed via a 63amp 3 phase supply. The transformer will then drop this to 220 volt 3 phase for the American control panel. The pool construction is steel with large motors and equipment bolted directly to the steel shell

I don't have a copy to hand. The incoming is a tncs. If a fault was to occur on the neutral earth connection at the cutout then the circuit would make the pool shell come live. By earthing the pool directly to an earth rod this would eliminate this problem. But could you also use the center...

Would you connect the metal pool shell and pump equipment to the main earth. Some people are saying it needs to be earthed to the main system. Some to an earth rod on its own earth and some say an isolating transformer. I can understand that if you was to loose the main earth, any fault current...

The Electricity Safety, Quality and Continuity Regulations 2002 (as amended) permit the Distribution Network Operator (DNO) to combine neutral and protective functions in a single conductor provided that, in addition to the neutral to earth connection at the supply transformer, there are one or...

Yes sorry uk to usa. It's a tncs incoming but regs say that in case of a failure on the incoming supply of the earth or slight volt drop in the earth cabling could result in voltages into the system. Hence why they say a earth rod.

I've been asked to install some american swimming pool equipment which requires a transformer to convert from american to USA voltages. The question is do i get the transformer with a center earth tapping and have a complete separate earth for the pool (pool tank is metal) from the center...
