C-H,
How do you guys test your RCD's over there, after installation?.
We had a really hot debate, going on amongst us Electrical people over here, as to what constituted a true test of the effectiveness of the RCD, some fella's reckoned that pushing the test button, satisfied the test requirements.
I have a dedicated RCD tester, and use it in every installation that has RCD's installed,regardless of wether or not I installed them.
One trend over in Australia that I do not like, is the practice of using a 50A RCD(S) downstream of the Main Switch, this protects the whole installation, so if one power point trips, the whole house is left dead, not good!.:mad
