I’m in Australia and have been having this battle now for well over a month. EVCC and Charge port replaced but no OBC replacement yet, has now been back in the shop twice for warranty repairs. MG say this time they cannot find the issue so the car has been handed back to me, but I bet it will...

Thanks for the info! So did yours charge at all, randomly? I had mine just charge on 7kW for about 20 minutes before spitting the dummy. Interesting that would leave a fault code?

What’s the difference between earth leakage detection and an RCD and how could an RCD work in an isolated system?

Just an update - the issue disappeared for a few weeks and is back again so I tried this - no help unfortunately. I’ve been chasing my dealer for 2 weeks to get it booked in but they’re horrible with returning calls.

Gotcha! Thought so So in which case I would think, your safety mechanisms in a V2L system are the RCD detecting a fault between the neutral/live and body of the vehicle (if the earth pin is attached to the vehicle body), or the good old circuit breaker under a short circuit fault through your...

I agree. And really I wonder if it truly is less safe, because if you touching a single conductor won’t cause a traditional ‘flow to earth’ as the neutral isn’t truly ‘earthed’ then is it really less safe? The dangerous fault condition in V2L is you somehow touching both conductors

THANK YOU 🙏 I do wonder though if you touched L and N and completed the circuit (and of course, had current flow through you), will the RCD ‘see’ it, as wouldn’t the current in and out of you be equal?

But why in a V2L would the circuit travel to earth if the neutral conductor itself is not earthed? Please, remember, the reason in a MEN grid system that electricity travels to earth is because the neutral is earthed at multiple points. In a V2L, IT system; the neutral is never earthed...

See how the title of that video says TN-C-S, TN-S and TT? V2L is not any of those. V2L is an IT system. Here is why RCDs don’t work in IT systems: https://powersafe.net.au/wp-content/uploads/2020/06/Powersafe-RCD-DUO-Safety.pdf

No, but electricity will flow any way to complete its circuit. Do you know why your home electrical system will flow to ‘earth’ if you touch it? It’s because the neutral conductor, which completes the circuit, is earthed at multiple points in the grid, including probably your earth stake at...

That article discusses an RCD working within a Multiple Earthed Neutral system, the most common grid connected system. Remember, a V2L system is not neutral-earthed, it is isolated, so that article does not apply to V2L systems.

On a grid system? In Australia it’s at the source, delivered via wire, and earthed at multiple points through the grid (and we also earth stake at the home)

The reason an RCD trips in your home if you touch a live conductor is because the neutral is earthed at multiple points not just on your home but throughout the grid. Electricity in a MEN system will want to travel to earth if you touch it as it completes the circuit, but in an isolated system...

Yes but L1 will only travel to earth if earth completes the circuit. Remember. In a V2L system, it does not have a multiple earthed neutral (MEN) system as it is floating/isolated. So if I touch the L1, why would it flow through me if I do not complete the circuit to N? And therefore, why would...

How would an RCD detect an imbalance without a reference to ground for the current to flow?
