Yea, what's the MCB for? I'm experiencing very pain shocks when I turn on my electric components in my room. It's kinda like an electric shock. It happens even when I touch the strings on my guitar, or the metal casing of my mixer.
Someone else told me it could be a grounding issue, but all the power sockets in my whole room is like that. Can someone help me solve this mystery? I'd be so grateful. THanks!
