3-phase is a way to supply more power on similar wires. If your oven is designed to be run off 3-phase, then it will need that. I've not seen any residential ovens wired that way, though. What makes you think it's wired 3-phase? If you are in the US, it's likely wired for 230v, which is 3 wires, but not 3-phase.
Your question is not mate. What do you exactly want to do? If I understand that you have a single phase apparatus you wanted to connect it from a three phase box. If that is the case, then you have three options: 1. If the wires are new colour coded ones then you have to take your neutral wire from the blue wire and the live from any of the other three. 2- for old colour codes , take the neutral from the black wire and the live from any of the other three. 3- finally. Connect the neutral from the black or blue and the live from any of the other three red ones if the wires are in a conduit or trunking. I hope this answers your questions. Good luck
you must understand this : your electric oven must be indicate if it is a single phase( use 3 wires for 230 2 hot wires + 1 Neutral see the diagram like dryer? you must sure about this. Normally any appliance for home are single phase NOT 3 phase.
2) If you electric oven, say 3 PHASES( use 4 WIRES, 3 hot wires+1 Neutral wires) this for industrial application +comercial NOT for home
However if you system is 3 phase you must need to install 3phase transformer.
use 3 -- 6 gauge copper wires, you could get by with 2--6 gauge wires for the two hot phases and 1--8 gauge for the neutral connection,but with that long a run use all 6 gauge so you don't experience any voltage drop,also in your community you may need to check the local codes on grounding and need to add a separate grounding wire,which you can use an 8 gauge for this wire connection, if you use aluminum wire(which I highly DO NOT reccomend) you will need to get one gauge larger as in 3--4 gauge aluminum to carry the same current as copper wire
It can be done with a transformer, 480/ 240 single phase transformer to get the lower voltage. Then the oven will require some wiring changes to get all the elements and controls connected to two hot wires instead of three. The transformed will be sized to the wattage rating of the oven. This is a only basic description of what needs to take place.
This is usually indicative of a short in the oven. Unplug the oven, and clean it out thoroughly. Be sure that nothing is crusted to the element, and that the power cord is not frayed or cut. Its likely that something inside the power supply is broken, and the oven may need a new supply, or need to be replaced if it is a cheap unit.
It could be but, the expense of replacing all the 3 phase controls would cost more than what it would be worth. Sell it and use the proceeds to purchase a single phase unit or if you are wanting to use it in a commercial building, see if you can have 3 phase installed by your electric provider.
Switching phase on products are usually up to UL. You need a good tech and it can be done. If it is marked 3 phase and you make a single, the responsibility falls on the person that did the conversion. Components should be similar from 3 phase to single, just use OEM parts!
