How to connect an oven and hob to a five-core cable
Hello! Help me to understand. A 5-core cable sticks out of the wall (in the shield it is connected to a 3-phase 16A circuit breaker). It is necessary to connect an oven for 220 V and 3.5 kW, as well as a hob for 5.9 kW and 220 V., how to do this? Need some terminal block, and which one? Where to connect another core (phase) from a 5-core cable, if the other two are connected to the cooking and oven?

If the appliance is single-phase, then it connects to one phase: for one device, take any phase, for the second, take any of the two remaining. The third phase will not be involved. Zero will be common to two electrical appliances, land too. To connect, you need a terminal block in which there will be enough terminals for branching the neutral and ground conductors. Also, this terminal block must withstand the load of these electrical appliances.
But before connecting, you need to make sure that your cable can withstand the load of these two electrical appliances. In this case, pay attention to zero - it must withstand the total load of these electrical appliances.
If the cross-section does not allow to connect such a load, then as an option one of the phases to which nothing will be connected, in the shield, disconnect from the machine and connect this wire to zero. And then you will have five veins: two zeros, two phases and a grounding conductor. But also this option can be practiced only on condition that your cable can withstand this load.
