Wiring Daigram

[LNW]

Hi

Can any body help? I am helping a friend wire up a sauna but we are confused by the wiring diagram I know where earth goes but where does live and neutral go and what is the loop between B and C?.

Thanks

The best help you can give your friend is to pay for an electrician to install the electrical wiring.

If you cannot work out where the Live and Neutral connect to then you appear to lack the minimum knowledge and skills to install this unit.

Are you sure you know where the earth has to be connected ? If it is outdoors then there are two options for earthing the unit. One methods presents less hazard to users than the other one.

Hard to tell from that ridiculously tiny drawing, but maybe in some places it uses 2 different phases, but over here it's linked and only needs 1 phase.

BUT...

If you don't even know where to connect L & N then you really should not be doing this - please get an electrician, you're not being a good friend by messing with things you don't understand, particularly with heaters and steam generators.

What circuit is being used to supply this?

the we have a chance of seeing the thing.

But you'll need a registered electrician to sort this out for you, even if you did that

pretty straightforward I thought! the loop from C-B provides a supply to B

So simple its a worry that LNW can't follow the diagram.

Lets hope there is a 30mA RCD protecting his "friend"

thats why I didnt say what to put where!

Thanks for this as it 4.5 KW that works out at less than 20 amps and probably 6mm or 4mm cable as the the run is only 5 meters.

Looks like originally it was exactly the US wiring which was discussed in a recent thread.

What reference method? As I suspect you don't need anything like that much cable in reality

The run from where is only 5m?

Oh well - connecting two 120V loads in parallel to a 230V supply will provide some entertainment.

I wonder if the OP's ill-served friend has the local fire station on speed-dial?

The cable will be run through plastic conduit and clipped to the ceiling. It does not pass through any insulation or floor joists

then I would revisit your cable calcs as you DEFINITELY do not need 6mm

So i am thinking that 4mm would be better on a 20 Amp MCB with 30ma RCD protection
