Rcds in series

Discuss Rcds in series in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net

the RCDs are wired in series, as the load current passes through RCD1 then RCD2. either one trips, the current is Zero. if they were in parallel, 1 RCD trips and the other one would pass the load current. here endeth the lesson. :p:rolleyes:o_O
