Why does an electric boiler shock through a stream of hot water?
Hello, the electric boiler began to shock, though very small. Beats when the hot water tap is opened, and when the RCD is turned on, and when it is turned off (plug in the socket). He pulled the plug from the outlet and saw that one of the plugs of the plug, as well as one of the sockets of the socket turned black and charred. RCD does not work at the same time. Moreover, all other electrical appliances are not shocked. Tell me what is the reason and how to be?

Hello! The RCD will not work if the outlet turns black. It is triggered by a current leak. Now the question is: RCD with which tripping current do you have installed? Is there grounding? If it is shocking when the RCD is off, then there are two options: either it does not break the phase, or it does not shock from your wiring. Is the heating circuit closed only inside your apartment? In general, check the RCD to start with a test lamp.
