New oven has 4 wires but house has only 3

Yeah ok , cant really afford a sparky and tired of toast for dinner :( guessing will have to get one tho to run another wire from breaker box ? Thank you for prompt reply

How many wires are there from the poles outside to the house (if you don't have underground power of course) - 2, 3 or 4?

2 = single phase

3 = 2 phase

4 = 3 phase.

underground of course :( so youre saying it may not even be able to be installed (Sad trumpet noise)

well im on an acreage and power does go to a pole in front paddock , and then underground to house , perhaps i can go for a drive down to the road and look ?

Not sure as I'm not an electrician and not up on the wiring rules.

I don't know if a two phase oven can be connected using two supplies (each with their own fuse) from a single phase power box or whether this may exceed the load and you need to have more than 1 phase supplied to the property.

You can check your power box and look to see how many cartridge fuses are located close to the power meter.

If there are 3 then you have 3 phase power, if only 1 then a single phase. 2 phase is rarer now as it is just as cheap to install 3 phase.

If you have 3 phase then all you need is for an electrician to run in an extra supply to the oven from the power box and connect it to the oven with the existing supply

if you only have single phase supply maybe ring an electrican and ask if your oven can be connected to it or if you need a 3 phase supply

It never hurts to ask ;-)
