Just bought a new stand alone Ariston Oven.
 
I was going to use the old four pin wall point and plug off my old oven.

I have just realised that the new oven only has  Earth, Netural, phase on its powercord, it is missing white..

Can i Just wire up the first three in the correct positions and ignore the extra 4th pin.

Please help i want to cook a pizza!!!!

I could i suppose just fit a normal 3 pin plug and run from a different outlet, but would prefer to run from the specific oven point beneath the bench.

Your call if you want to play with a 30amp fitting. 
I think you need a sparky to be honest.  Your generally not allowed to fiddle with anything thats hard wired back to the fuse box.

Does the exemption for home owners fitting their own fixed wiring appliances not extend to freestanding ranges?

In anycase. In all the houses I have had that have swapped ranges over, have never come across a 4 wire plug. Always just been a giant version of a 3 pin plug in the old ones, and one about the same size but chunky pins with bends in them (Ugly HPM ones)

What does the 4th wire connect to?

I'm all for giving something a go in your own house... but that's a fairly serious outlet you are playing with there. A sparky is only going to take maybe half an hour at the most and personally that is the route I would go down for something like this.

When it's plugged in it's not a "fixed wiring appliance"

The 4 pin plug is a 2 phase version, back when it was common to have 3 phase in the house the range was 2 phase, the top elements on 1 phase and the oven on the other phase. for houses with one phase supply, typically there was an internal link in the range to run it off 1 phase.

You more than likely have the PDL 4 pin range plug, don't forget to tell your electrician that when you ring so they can bring one with.

Anyway, I would recommend that you get your electrician to fit a 4 pin plug and cord to your new range, ask for your Electrical safety certificate, this is the documentation you file away so if there is a fire that is related to this work you can show your insurance company and your insurance will cover you, if you DIY and there is a problem this is an out clause for your insurance and you know what insurance companies are like at trying to avoid paying.

What Greg said.

Also, you absolutely can not put a standard 3 pin plug on it.

Thanks all for you speedy replies, as we are selling the house, I think I will go the Electrician route.

Having a electrical certificate of compliance to code  for it would give me peace of mind.  

Very annoying spent a lot of time moving that point from one wall to the new internal stud i have just put up.

I just assumed a standalone was made to be moved around, hence the four pin plug on our last two old ovens.

Time to find an Electrician!

Yeah on the last range I changed it had a diagram on the cover to wire it up either for single, dual or three phase star and 3 phase delta with a whole lot of links supplied to go between the different terminals for whatever configuration you needed. Came set up for single phase so just whacked the cable into it and away it went.

Im still annoyed that we dumped the first range with the cable on it because it was crazy expensive for another one. Lesson learnt from that tho.

If you've already shifted the socket that's work that the electrician would have had to supply a cert for. Putting a cord on the appliance isn't something that he's obliged to supply an ESC for as it is not work on the fixed installation.

any electrical work done requires at least an ESC, this states that the work done is safe to connect

ESR74A refers to ESCs for work on "Installations" ie the fixed wiring. Fitting a cord to an appliance requires testing but there isn't the same paperwork. www.electricalforum.co.nz has several threads covering this issue.

In conclusion to this topic, the Electrician wired up the four pin plug as i had done.  After confirming, the fuses on the board and been updated to a single fuse for both hob and oven we switched on and all working.  So in the end has cost me $60.00 for peace of mind. No regrets getting the Electrician to rewire what i had wired, then unwired to rewire my old oven so i could eat over the last few day;P
