Why the RCD in the shield does not turn on?

Good afternoon. Tell me why the RCD does not turn on. We stopped in a new apartment and wanted to find out which outlet this or that machine corresponds to. I checked it with a drill, reached the outlet near the bathtub, apparently she was going to the washing machine, turned on the drill, the outlet was working. I turned off the RCD manually, turned on the drill, everything is correct, the drill is silent. I pulled out the drill, but I can not turn it on the RCD. What is the reason? UZO brand I can not say, China, like a starter. thank

    If you manually turned off the RCD and it does not turn on, then there is probably a malfunction in this RCD. Connect this wiring line to a known working RCD, if it does not work, then the wiring is in order and you just need to replace the RCD installed to protect this line with a new one.
