Hi folks,
My family and I are living in a terrace house.
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?

As mention the ELCB for 100mA will trip frequently during storms is a norm. Its prove that your ELCB working. If the ELCB never trip at all, you are in trouble. ELCB is a safety device used in electrical installations with high earth impedance to prevent SHOCK and to protect your SENSITIVE equipment/home appliances.
The ELCB rating should be as low as possible to prevent shock; do you think that 100mA is safe enough for human and equipment? NO. IEC 60479 stated that human cannot take in more than 7mA of leakage current. More than that are critical level and may cause to DEATH. Unfortunately, the current ELCB lowest rating is 10mA whereby still a risk to human against SHOCK. If you choose to use 30mA at your main, you will complain that it trip more frequent as compare to your assisting one (100mA).
I have the solution where comply to IEC 60479 and eliminate nuisance trip…
