Difference between ELCB and RCCB ELCB is the old name and often refers to voltage operated devices that are no longer available and it is advised you replace them if you find one. RCCB or RCD is the new name that specifies current operated (hence the new name to distinguish from voltage operated).

Driver For Toshiba E-studio Printer. Hi folks, My family and I are living in a terrace house. Mp Navigator Canon Pixma Mp160 Scanner. Recently my dad changed our 25-yr old voltage-based ELCB to a newer current-based RCCB (Wylex 2Pole 40A with 100mA sensitivity) After that it start nuisance tripping a lot during storms, even if the lightning is far away.

When no storm, everything is OK. I was surprised even 100mA also trips a lot, if 30mA of course I can understand the tripping. Any RCCB users here on 100mA sensitivity? Do yours trip frequently during storms?

If yes, what did you do to mitigate the annoyance? This post has been edited by socratesman: Mar 15 2011, 12:30 PM. Hi folks, My family and I are living in a terrace house.

Ideally, Live + Neutral = 0, if Live + Neutral /= 0, leakage happen. But, there's no ideal in real life, so, comes the Ioan where it is the tolerance the device will accept before registering the leakage as a fault, in your case, 100mA.

Generally, for lighting circuit, 100mA is used, 30mA is used for power circuit and 300mA for Air-Con. As for your problem, how old is your house, particularly, the electrical wiring? The older the wiring, the higher the probability of leakage through wires due to degration of the insulator. Proper solution, do a complete insulation test to the whole house, or change all the wiring. Improve your house earthing system. Cheap solution, which profesional do not agree, but client will usually do due to cost saving. Use higher tolerance RCCB or use ELCB instead.

No matter how do it, make sure other than the fuse, there's at least a protection device in place. Thanks for the very informative feedback.

My house is well over ten years as I bought it ten years ago. You are most probably right that some wire insulation has degraded to a point where there is earth leakage during lightning which trip the RCCB.

My thought was to isolate certain area/wiring where leakage is suspected by selectively turn off the DPN MCB during lighning. What is the best method of identifying the area/wiring other than doing a complete insulation test for the whole house? Typically how long and the cost of doing a complete insulation test for a semi-D single storey house?

I thought RCCB is the current version of ELCB. Pls elaborate on 'use ELCB instead' TQ and have a nice day.
