I bought this induction hob (that sits on the table top), and I need to connect it to the wires.
The problem is that there are 5 wires, the hob came with a cable that joined 4 wires into 2 pairs at the end. That cable was too short so I switched it to a longer one (same thickness, same color coding).
The built-in cable had the cables arranged in the first arrangement (32A 1N ~)
Seeing the slight damage, and knowing that another socket in my apartment has intermittent working issues (I'll deal with that separately), I wanted to make sure that my hob won't blow up when I connect it, so I took a cheap chinese multimeter and measured the voltage on each of the pairs.
And there I was, in shock:
- Blue - Brown = 230V
- Brown - Gray = 150V
- Brown - Black = 90V
- Black - Gray = 60V
- Blue - Gray = 60V
- Blue - Black = 120V
So no other situation is applicable other than the first one (32A 1N ~). Except that I have a problem with that, since my main switches that I guess are for this circuit are rated at 25A, so I guess that if I'll ever use them at 30A, they will automatically switch off, so I can't use my hob properly this way.
So I have the following questions:
- What's going on? Why does my cheap multimeter measure 230V on one pair, and ludicrous values (60V) on others?
- What would happen if I connect every wire to its respective color (thus possibly getting 60V instead of 220-240V)?
- Are the automatic switches so sensitive that they do turn off at exactly 25A? Or can they go higher than their rating?
- Is it possible that wires from 2 different switches converge into the same color? (in the photo you can see 2 blue wires, 2 brown wires, and 2 striped wires, so maybe I have 2x25A)
