Can anyone advise about hard wiring a brand new stove?
Question:Australian Electrical Wiring.
We have bought a brand new Lofra oven and want to hard wire it together with the large power cable coming out of the wall - which runs off a 32amp fuse.
The large cable on the wall has red, black and green colour coded cables. From researching the net, Red=Active, Black=Neutral, Green=Earth. Is this correct?
My problem is, inside the stove the colours of the cables are Blue, Brown and Green/Yellow. I know Green is to Green/Yellow=Earth. Do I then join the Red to the Brown and Black to the Blue? Because I read some confusing information on the net which has made me a little unsure.
Please do not suggest for me to call the electrician, because if I had the funds to do so I would have done so a long time ago, this oven has been sitting in its box for 6 months. And yes, I turned off the power at the main and took the fuse off. Please any real help I can get would be greatly appreciated. Thanks.
Answers:
your stove is probably 240v right? there should be a label on it or somewhere in the directions it should tell you the rating of the stove...i.e. 240v... 40Amps or 30 Amps. here in America black and red would be the 240v.. one red to ground is 120v and one black to ground is 120v. green or green/yellow is always ground. we put a neutral wire, usually white, and the ground is an extra safety measure... that is a 4 -wire system. i don't know what code is in Australia. black to blue and brown to red, if it is 240v. check the instructions and look for a wiring diagram. if the breaker supplying the wires to the stove is a one piece block usually with 2 switches that are attached to trip simultaneously... codes are there for a reason... mainly fire hazards... be sure all your wires, wire nuts and breaker are rated for the proper amperage... there are guides to what size wire you must have for a certain ampacity... don't take short cuts... you can cause a fire . don't you know any elect. to consult with?
I would certainly get a professional to come in to do it when it comes to electrical Wiring. Why would you take any ones advise here, They may kill you.
I would call a appliance parts store they will usualy help you out. Everyone is making this way to complicated.
I don't know code in Australia or how the current is set up so it is hard to advise but I will do the best I can to tell you what you need to look for.
Ground = Earth
Check the manual to see what the amperage is if it is a 50 amp stove then you need a 50-amp fuse (40 at the smallest if you want to increase the safety of the circuit). It should have no smaller then 8 gauge copper wire But check code to make sure this is big enough for where you live & the distance you have to run it. 40 amp no smaller the 30 amp fuse & 10 gauge wire. Again check code.
As for hook up use a tester to check voltage between red & black, red & green, & black & green.
Now with those readings if there is no reading between black & red then it is a single-phase circuit. If between black & red is twice as much as between red & green & black & green it is a two-phase circuit.
If there is no voltage between black & green they are both grounds (black being neural & green being ground.
The manual should take you from there.
Hear it would be black & red would hot. Making it a two phase. In this case it doesn’t mater which one the red & black is hooked to as long as the ground is hooked to the ground on the stove.
I hope I didn't make this to confusing.
Best of luck.
The international color codes used for three phase electrical wiring are shown in this table:
http://en.wikipedia.org/wiki/three-phase...
Since you've got single phase power, you're only interested in the columns for L1, Neutral, and Ground (Earth). (L2 and L3 are for the other two phases, which are rarely used in residential installations.)
The table shows that in Australia that L1 is red, Neutral is black, and Ground is green. Furthermore, it shows that in Europe that L1 is brown, Neutral is blue, and Ground is green/yellow striped.
Lofra ovens, being made in Italy, conform to the European color codes. You are quite correct that red is connected to brown, black is connected to blue, and green is connected to green/yellow.
