The easiest English word to use here is "difference", where the current flowing in one conductor minus the current flowing in the other conductor should show a difference of zero (or damn close), paying attention to the polarity of the transformer or other sensor. |

re, I understand that the circuit breaker will act on a difference of current. But in my case, I am protected on this old installation only by a circuit breaker of 500MA, since there is no circuit breaker 30MA. So I have to change the installation. here an example the effect of current intensity on the human body cdt |

An RCD is not considered a circuit breaker (though devices exist that combine both functions). French wiki says: --- Quote ---Dans le langage courant, et notamment lorsque l'on parle de l'équipement d'un tableau de répartition électrique, les disjoncteurs différentiels sont simplement appelés « différentiels », alors que le terme « disjoncteur » est réservé aux disjoncteurs électro-magnétiques. --- End quote --- Thus: disjoncteur = disjoncteur électro-magnétique = circuit breaker differentiel = disjoncteur différentiel = dispositif différentiel à courant résiduel (DDR) = RCD (also known as GFCI in North America) Also, mA is not the same as MA. mA = milliamp (1/1000th of an amp), MA = megaamp (1 million amps). I'll assume you actually mean milliamps. ;) So are you saying that right now, the circuit is protected by a 500mA RCD? That certainly, um, isn't for protecting human life! :P |

It doesn't matter if you use "m" or "M", so long as you are sincere. |
