Today I turned on my water boiler, and all the lights in my apartment turned off. I opened the electricity box and saw the RCD was tripped. I turned it back on, but then it would trip again whenever the water boiler was running.
I cursed my luck because I figured I have to fix my water boiler.
I then turned on the drier, and after a few seconds the RCD tripped again. I turned the RCD back on, and later turned on the AC. After a few seconds, the RCD trips again.
Right now as I'm typing this, the RCD isn't tripping and the electricity is on, but no high-wattage device like the above three is running. Can I conclude that high wattage is what's causing the problem? Maybe the RCD is faulty and I need to replace a fuse or the entire thing? Or maybe the problem is entirely different? I'll be happy to hear your thoughts.
