+Derek Stuart If upstream neutral voltage drop is high enough, such that there is enough voltage neutral-earth at this point, the earth loop impedance is low enough , then the RCCB CAN trip just with the neutral-earth fault attached, as it can actually cause that 25..30mA to leak from the low neutral voltafe through your fault back to supply. It all depends upon the exact resistance of circuit conductor, earthing arrangement, bonding, and so-on, in combination.
Chris This video was made to clearly demonstrate that WITHOUT a load being present, the earth leakage will NOT TRIP ON A NEUTRAL FAULT. Listen to the first sentence in the video. Was not made with the intention to mislead anyone. Peace out .. Derek
Hey sir, i want advice. Since we had replaced our geyser the taps shocks. The 2 water lines is earth at the geyser from the gyser isolator. The electricians wired the geyser neutral and earth togeter could that be the problem why the taps shocks?
@@jpreichert2585 The earth and neutral should not be connected together anywhere on the installation on the load side of the main circuit breaker or isolator. They must NOT be connected together at the geyser.
99% of the time, tingling taps are caused by a high neutral impedance on the line somewhere between your property and the substation. Any registered electrician with a loop impedance tester will be able to confirm if the supply cable is in order by doing an earth loop impedance and neutral loop impedance test. Both readings should be the same. If the neutral reading is higher than the earth reading then the incoming neutral from the supply authority has a bad connection somewhere along the line.
Thank you very much , we disconnected al the neutral wires what was conected to the earth that was installed by electricians through the insurance. But the problem is not solved yet. I wil get electricians out in my erea. But thanks alot for the reply i appreciate it
i have similar problem. at home, i guess my home. wiring. has earth and neutral short at some or a point, but I couldn't find it as there are more than 15 sockets until my home. It doesn't trip immediately, but drip randomly, could be in a few hours to a day
Hi Derek I don't have a earth wire in my mains can I just put a earth pin in the ground and connect earth from there coz I have heard people talk about earth and neutral bonding
Ok brother. Yes. Hit in an earth spike and bring in a cable to your DB for the consumer earthi g terminal. You can then bond your neutral to earth. Very important that the bonding is ďone BEFORE or on the supply side of the main isolaror or main breaker. Usually done at the municipal or eskom meter. We have whole suburbs where no earth is supplied.

Theoretically it should have tripped, unless that earth is not properly grounded.
Thanks
Awesome Derek, thats alot bru!
It literally says 0.03 A on the device. It will not trip without current, like its supposed to.

pls help me how to find out. the short point😢
I'm sitting with the same problem. It's the very reason why I'm here 😂

Hi Reagan. Where are you . In SA ?

@@derekstuart9717 thanks bro
Your neutral and earth might be provided by the same cable - so in this scenario it won’t trip
It´s a type AC RCD which should not be userd anymore... go for type A
Earth and neutral conductors are the same potential- all referenced to earth
