A single-pole MCB on one branch is off, but that branch neutral remains connected to the RCD&#8217;s neutral system. If neutral is unintentionally connected to protective earth downstream, current from another operating load may divide between the intended neutral return and the unintended earth path. The RCD can detect the difference and trip. The trip may happen only when another appliance starts, making the switched-off branch easy to overlook.<\/p>\n<p>This explanation follows from the RCD&#8217;s current-balance principle. It does not mean every trip with an MCB off is caused by a neutral\u2013earth fault.
