About :

The residual current circuit breaker, DR, is a device for detecting electrical current leaks. And consequently, it prevents electric shocks, which is why the DR is a mandatory item in NRB5410 in some situations such as wet areas. However, its use together with the main circuit breaker can cause installation problems, and this should be avoided. In this video, we will detail, according to NBR5410, where to use the DR and where not to use the DR, as the standard is very clear in which situations it allows you to not have the additional protection of the 30ma residual circuit breaker, and only rely on equipotentialization and the use of other means such as the use of barriers and enclosures.
