3 Phase Rccb Connection Diagram. The lower four terminals and ground wire of rcbo has been connected to the spa control box by the following sequence. For wiring rcd four pole circuit breaker connect your incoming 3 phase 4 wire supply to the input connection of fixed rcd e g example connect neutral n and phases l1 l2 l3 to input terminals and then get supply form out terminals as shown in below diagram.
This video about the rccb working principle rccb wiring connection and residual current circuit breaker installation diagram explanation rcd wiring dia. For wiring rcd four pole circuit breaker connect your incoming 3 phase 4 wire supply to the input connection of fixed rcd e g example connect neutral n and phases l1 l2 l3 to input terminals and then get supply form out terminals as shown in below diagram. Rccbs are not suitable for use on dc systems and unearthed networks.
Rccbs domestic installation rccbs can be installed in two ways.
A test switch is used to check the working condition of rccb. Rccbs are not suitable for use on dc systems and unearthed networks. In that a switch is connected between line to earth in series with a resistor. For wiring rcd four pole circuit breaker connect your incoming 3 phase 4 wire supply to the input connection of fixed rcd e g example connect neutral n and phases l1 l2 l3 to input terminals and then get supply form out terminals as shown in below diagram.
