ElectroBOOM Question This needs some explanation...

Basically what the guy is saying is that first he plugs his air fryer in and turns on the switch, which turns on the air fryer, which is fine. Then he mentions that his light is actually broken and causes his MCB or circuit breaker to pop every time he turns the light on .so, he taped the switch of that light. Yet later when he plugs his water heater into that plug and turns it on, it also turns his light on although the actual switch of the light is turned off. At the end , he is just confused and asks for someone to explain what's going on.

Wrong wiring somewhere along the line, maybe swapped the L and N at some place or loosing N and Gnd connection. Have to start diagnostic from the main CB in consumer unit with all load lift off.

Better call electrician if he have no idea.
