QUOTE(PJusa @ Mar 15 2011, 02:00 PM) disconnected mine for the same reason. 100mA provides no safety anyway to humans. neither does 30 mA - you would need max. of 10mA for that. Please don't be silly to disconnect it as it's for your own protection. Many times that my RCCB has tripped, it's due to some malfunction in my house electrical equipment. Sometimes there's a residual leak in your house that's tripping your ELCB/RCCB. |

QUOTE(PJusa @ Mar 15 2013, 11:14 PM) disconnecting an ELCB that cant by definition do what it should do because the threshold is too high is not silly. if the ELCB will only act AFTER its too late because its rating is too high what's the use? i can also place another spare on on top of my meter for the looks of it and it would have almost the same effect. ok, scenario..There's a short/earth leakage in the kettle. ELCB/RCCB detects it and turns off power. If the ELCB didn't work, you could have touched the kettle and electrocuted yourself.scenario 2.. You touch a live wire and current starts flowing through you. Since it's electricity, your muscles seize and you can't let go. RCCB detects it and cuts off the power. 10mA flows through you compared to 10000mA. The amount of of mA that it takes to kill you is very subjective. It depends on the path to ground. Whether it goes thru your heart or not etc. This post has been edited by jovial: Mar 28 2013, 07:50 AM |
