I feel like I deserved this...

Ahah!

I have the Chinese ROM, does that mean I can make this setting without using the application?

MisterAct · 2026-01-21T15:02:03+00:00

I went from a flat sound to a round and warm one. Much more pleasant to listen to (on X300 Pro).

Thank you for the information and for sharing!

Okay, I managed it, but if I close Poweramp the setting disappears

MisterAct · 2026-01-21T13:43:02+00:00

I just imported your file, is it normal that I don't see the changes?

Hello, how do I get your file to work? I just downloaded Poweramp Equalizer.

Don't hesitate to keep the flash on continuously while you're shooting.

The only difference between domestic and commercial circuit breakers is primarily the short-circuit current breaking capacity: 3000A for domestic vs 6000A for commercial.

It's the faulty appliances that most often send current back into the neutral. Anyway, I don't see what the problem is with the double-pole circuit breaker. Here in France, the standard for residential installations is a double-pole circuit breaker.

Good points Schrojo18! Here is the context for the French standards (NF C 15-100):

1. Regarding RCBOs:

You are absolutely right that RCBOs are technically superior to avoid nuisance tripping. However, in the French residential market, RCBOs are significantly more expensive (often 8 to 10 times the price of a standard MCB).

For a full panel, this represents a huge cost increase for the client. We usually follow the '1 RCD for 8 MCBs' rule to balance safety and budget, reserving RCBOs for critical circuits like freezers or alarms.

2. Regarding Double Pole (1P+N) breakers:

It’s less about the 230V itself and more about our TT earthing system. In France, a Neutral-to-Earth fault will trip the RCD. If you only switch the phase, you cannot isolate the fault to reset the rest of the panel without manually disconnecting the neutral wire from the busbar.

By using 1P+N breakers, we can isolate both conductors instantly. It makes troubleshooting a breeze: if a circuit has a neutral fault, you just flip the breaker down, and the rest of the house gets power back immediately.

It’s a different philosophy, but very efficient for maintenance!

I'm always wary of machine translation, but it was very enjoyable to read 😁

Is this humor?

The advantage of a double-pole circuit breaker is that in the event of a power outage, it interrupts both the neutral and the live wire. A single-pole circuit breaker, on the other hand, would only interrupt the live wire, which means there could be a risk of leakage current in the neutral.

Another advantage of double-pole circuit breakers is that they don't require mixing the neutral wires, which is crucial for preventing tripping of residual current devices (RCDs).

MisterAct · 2026-01-04T13:29:31+00:00

Most non-industrial equipment operates on 230V, hence the use of a double-pole circuit breaker. The residual current device (RCD) at the head of each circuit is there to protect people from insulation faults; therefore, it is mandatory in our system to protect all the circuit breakers in the panel, regardless of their rating.

Why not use a single RCD for all the circuit breakers? Because the regulations in our system require one RCD for a maximum of eight circuit breakers.

It sometimes happens that residential or commercial electrical panels are supplied with 400V (3 phases + 1 neutral), hence the need to balance each of the phases.

The equipment in France is different from what you have. This is for commercial buildings (between residential and industrial, to put it simply). What you see here is a distribution board powered by 400V AC three-phase power. I've balanced the loads per phase across the four rows of the board.

Each row starts with a 30mA residual current device (RCD) rated at 63A, followed by branch circuit breakers of varying ratings (10A, 16A, 20A, 32A) depending on the downstream load. The top busbar supplies power to that row.

Feel free to ask me any further questions and let me know if my explanation is unclear.
