Variable Time Delay Rcd at Bessie Perrone blog

Variable Time Delay Rcd. Installing rcds with different ma ratings and or time delayed devices is not a new concept. A time delayed rcd should always be used if other rcd's / rcbo's are connected after them. Best practice for using surge protective devices (spds) and rcd together For more information and connection between rcds and surge arresters feel free to read: However, the major change that came in with bs 7671:2018 is the requirement to select the appropriate type of rcd, ac, a, f, or b dependent on the expected load. If the rcd is downstream, a standard rcd may be used. Variable time and residual current setting allow for horizontal and vertical discrimination when more than one rcd is. This will allow the other rcd's to operate. High sensitivity rcds (iδn = 30ma) provide both protection against indirect contact hazards and the additional protection against the dangers of direct.
