Our old free standing oven is playing up, and we are weighing up whether to get it repaired or just replace it.

 

Part of the decision will come down to whether we are required to have an electrician install it, as if an electrician is required then that adds to the cost.

 

Current oven has a nice simple 240v single phase feed going into it, and we would replace it with an equivalent unit.

 

NZECP 51:2004 has a section about the requirements of wiring the oven, which I assume means as the home owner I am legally allowed to do it myself. But the website for the oven I'm looking at specifically says "Electrical Installations must be undertaken by a licensed electrical worker".

 

So, am I allowed to do this or not?

 

Thanks

Has your current one got a Range plug, or is it hard-wired into the wall socket?

 

I replaced mine once (a few years back, a couple of houses ago) and it had a range plug. I unplugged it from the wall, removed the range plug from the old oven (three screws) and connected it to the new oven. Plugged in and all away again. I had checked that the current ratings were the same for both ovens.

Hard-wired into the wall socket.

 

Looking at the manual of the replacement I was considering it may not be suitable anyway as it appears to be for 3 phase and it doesn't mention an option for wiring it single phase. Since the vast majority of NZ houses only have single phase I assume this oven can be wired to work that way, but lacking a clear wiring diagram I wouldn't want to try myself.

When we did ours a few years ago the deal included delivery and installation ( $50 ) 

 

The installer wired the oven direct to the wall ( he had limited electrical registration A & B ) ( same as me but for $50 it not worth my time to pi$$ around and he did all the heavy lifting )

 

Freestanding ovens are designed to be run on two phases ( I have not see three phase ) and there is a link that has to be removed if you do run on two phases. 

 

If your are asking electrical questions like this here indicated you should get an electrician / installer to do it safely for you.

It may still be fine for single phase. I used to have an Ilve double wall oven, which could run from 1,2, or 3 phase. It had a diagram on the back which said which terminals had to be linked together, depending on how many phases were available. It was even able to use both star and delta 3 phase power.

Post a picture of the rating plate if you are unsure if the new oven will support single phase. Before you buy it. If the new oven is a European brand, 3 phase power is alot more common over there. But single phase is also common there as well.

ECP51 specifically allows a home owner to connect and disconnect fixed wired appliances - 47 (1) (c),

 

The problem if you choose to DIY is that should a fault develop your guarantee could be denied as you failed to follow the manufactures instructions with said use an electrician to install.

Under Regulation 57 of Electrical Regulations 2010 you can disconnect and reconnection permanently wired appliances on existing wiring - so go for it !

And should the "fault" include setting fire to your kitchen / burning your house down 😱 then it might also be a good enough excuse for your insurance provider to just shrug and walk away. They can be like that.

 

I recently replaced my stove, and purchased (from Noel Leemings) the "install the new stove and haul the old one away" option. No fuss, no mess, no bother, no tipping fees. Well worth it in my view

All sounds too paranoid IMO, its replacing an oven, not new wiring to switch board or new cabling. Its  simple like for like, one thing you should do is ensure earth is connected properly and check this if you have a meter, if you get wiring wrong you will hear a bang and blow a fuse.

Yeah, I assume it probably is OK for single phase it's just there is nothing in the manual about it and I wouldn't want to guess at what needs to be bridged. Haven't been in store to see if there is an additional diagram on the back, or to see the rating plate.

 

Others have mentioned delivery might include installation (I hadn't actually considered that) and if that's the case I'd just get them to do it - but obviously I need to ensure it is definitely OK on single phase before ordering (or get a guarantee from them that it is, so I can reject it if it arrives and it's 3 phase only).

 

Thanks
