Use of commercial electric ovens. The problem of wire load of watt hour meter.
The three-phase power supply, current 6.5KW 17A, because the power is not large, 6 square copper conductors, 20-32A circuit breaker (do not know whether the use of AC contactor control), 20A three-phase four wire watt hour meter, these are basically similar.
The need to consider the power line to take effect on electric oven, current =6.5KW/220V=29.5; the 6.5KW copper wiring 4 mm square meter, more than 30A, if the meter with other appliances, to calculate the current of all electrical appliances, can choose how much of the meter.These questions are very simple for electricians. Just get an electrician to handle them!
You should first distinguish between 220V or 380V voltage products. Although they are all 6.5KW, the 220V has only one set of heating wires, and the 380V has three sets of heating wires.1. voltage is 220V, power is 6.5KW, the general family of power lines is enough, the original watt hour meter can also be used, do not need to go to the power supply department. Wires are usually 4mm2 enough, too. If you have only 2.5mm2 wires in your house, you can use them. But the socket to be dedicated, the line must be dedicated.The 2 voltage is 380V, which is a three-phase power supply, ordinary families do not have three-phase power (only the villa and high-grade residential, it should be a three-phase power supply) to the power supply department to apply for installation of three-phase power supply, will be on-site installation (including wire wire, three-phase meter, pipe joints, three-phase power distribution the box and so on something). The cost is all out of you (including labor expense).
