And then instantly disconnect the electricity flow in the connected. Here is the rcd wiring diagram in which i install the main distribution board.
Difference Between Mcb Mccb Elcb And Rcb Rcd Or Rccb
Rcd circuit breaker wiring diagram. This circuit breaker wiring diagram illustrates installing a 20 amp circuit breaker for a 240 volt circuit. The three phase wiring for gfci or rcd rccb or rcbo wiring diagram shows the three lines l1 l2 and l3 and neutral has been connected as input to the rccb from main board followed by mcb ie. A residual current device or residual current circuit breaker is an electrical wiring device or switch that disconnects or trip a circuit whenever it detects that the electric current is not balanced between the energized conductor l and the return neutral conductor n. Double pole mcb dp the isolator or main switch. A neutral wire is not used in this circuit. The lower four terminals and ground wire of rcbo has been connected to the spa control box by the following sequence.
Rcd wiring installation in single phase distribution board the wiring installation of rcd is very simple in main distribution board you need to connect the fixed rcd after the main two pole circuit breaker. For wiring rcd four pole circuit breaker connect your incoming 3 phase 4 wire supply to the input connection of fixed rcd eg example connect neutral n and phases l1 l2 l3 to input terminals and then get supply form out terminals as shown in below diagram. The following is a given wiring diagram of a single phase distribution board with rcd in both the nec and iec electrical wiring color codes. The white wire is used for hot in this circuit and it is marked with black tape on both ends to identify it as such. The same description and details can be used as described in fig. The 122 gauge cable for this circuit includes 2 conductors and 1 ground.
