Can I use 600W electric kettle in a circuit which has a MCB rated as C2?
The power supply voltage is 220V.

There is a simple formula that relates Volts, Watts and Amps.
W = V * A
You know the watts and the volts, and need to know amps to compare that to your circuit breaker. Basic algebra tells us that Amps is going to be Watts divided by Voltage. So, your kettle is going to use
600W / 220V = 2.7A (about 3 Amps)
A C2 breaker is rated for 2 Amps, so it would not be sufficient for that kettle.
Both your circuits' hots are red wires... Ok... But I follow them, and several pairs of wires are cable-tied together which suggests 240V or MWBCs, ok..., and they both disappear into the bottom conduit, where--
What, the, actual, heck...???
-- there's like 20 red and black wires going into this fat conduit, And Only One Neutral!
You can't do that!!! A bajillion circuits can't share a neutral! Each hot gets its own neutral, except for MWBCs where two hots share 1 neutral. You can't have a MMMMMMMMWBC!
You also can't put more than 9 wires in a conduit without derating (using thicker wire).
This is either a total nightmare, or needs some serious explaining. Who did this work?
This indicates that you have a higher resistance in the service connection than there should be. I think you should get a service call from a competent electrician.
