Oh and quick PSA: Regardless of it’s whole house protection, or individual socket protection, you should test the function of your RCDs every now and again. Officially at least once a month. Every RCD breaker has a little button somewhere labeled “test”, that connects L to GND across a resistor, to check if the breaker actually does it’s job. If you’ve never done this (and haven’t recently had the RCD trip for an actual fault) GO DO IT NOW. THOSE THINGS ARE LITERALLY LIFE SAVERS AND IT’S IMPORTANT TO MAKE SURE THEY’RE ACTUALLY WORKING.

Such good advice.
