The ability to connect the hob and oven to the cable 5 * 2.5
After the repair, the electrician left the cable outlet 5x2.5 for the hob and oven. He explained that it is possible to perform the connection and there is no violation of GOST. The purchased hob has a power of 7.1 kW and an oven power of 2980 watts. Is the electrician right? Or do you need to redo the wiring?
