electric oven

[Damo182]

I am in the same boat, we have just bought an electric oven that is replacing a gas one. When we had our Air Con installed the sparkie told us we would need to get more power from the pole as we did not have enough power coming in

Now we are having an oven installed i am guessing this will need to be done, Is there a way to see if my current system can handle the addition of an oven?

Any ideas on how much this will cost? I have a really old fuse box which will need to be replaced, probably with a 9 or 12 circuit fuse box.

I am in Drummoyne Sydney, any sparkies who can do a good cash price send me a pm

Unusual way of denoting cable size

I think we are confusing diameters and mm2 guys

Cheers

you got it - the BIL sparky, first used a thickness measure when gesticulating what it could be, then for the next size down spoke witha bigger number - huh? ie mm^2. too confusing to me, but having seen the cable, my picture in the head estimate is about 9 or 10mm diameter including sheath - so probably 16mm^2 which would be about 4.51251mm diameter of actual copper - though you never no - could be 25mm^2

Any Sparkie should be able to do this for you

Smurf what you have done is perfectly OK with 2 exceptions.

1/ If the circuit is protected by a RCD(Safety switch) you may find within time the oven will trip (turn OFF) the RCD
Ovens and hobs are about the only thing we don't have to protect with an RCD because of the nuisance tripping factor.
Thats why we like to put ovens on a separate Circuit

2/You have said that the oven is just under 2300W.
Thats pulling around 10 amps
Once again thats OK as long as you don't have much else on the same circuit.
As I assume that oven is on the same circuit as the rest of the Kitchen or maybe a bathroom or laundry all contain some sort of heating appliance.
Let say SHMBO is cooking a roast and some cooks toast or drys there hair and the heating element of the appliance is roughly the same 2300W theres 20amp being pulled and there blows the circuit breaker or fuse and maybe spoiled roast

Another reason to put an oven on its own circuit.

Yep. I know that.

For the moment it's on a power circuit, same one as the dishwasher and a few other minor loads. But I can't see the dishwasher and oven on at the same time (wouldn't make much sense) so OK so far. And with 4 power circuits in the house the other big things are all on other circuits so no problems there. Also I have two heaters, one electric on its own circuit (and own meter) and the other wood, so no need to run plug-in fan heaters etc.

I'm licensed to do it so I'll just run a separate circuit for the oven if / when it becomes a problem. So far so good though. Only thing I was a bit worried about was the elements tripping the RCD but again so far so good.
