4 Pole RCCB RCD Wiring Diagram For 3 Phase 4 Wire System

In my last published post, I shared a diagram about double pole RCD wiring diagram, and now in this post, we also publish a diagram about RCD breaker but this diagram is about 4 pole RCCB or RCD which we can use in 3 phase 4 wire system for protection.
I will share more nice and important tutorials about the complete installation of RCCB or RCD Breaker in homes, but in this post, I want to teach you about only 4 pole RCD circuit breaker wiring. This is a basic diagram and IN SH ALLAH soon we will make more examples and helpful diagrams, from which you will learn easily.

How to Wire A 4 Pole RCD Circuit Breaker

In RCD 4 pole breaker we have 8 terminals, where 4 terminals for input supply and 4 for output supply just like a 4 pole MCCB circuit breaker and not only it’s like 4 pole circuit breaker, but its wiring method is also the same.

For wiring the RCD four pole circuit breaker connect your incoming 3 phase 4 wire supply to the input connection of fixed RCCB, E.g example connects neutral N and Phases L1, L2, and L3 to input terminals and then get supply from out terminals as shown in below diagram.

The above Image + diagram is just an example, and RCD is available in many shapes and types, however, you can use this method in wiring a 4-pole RCD. If you use 3 phase 4-wire system supply then instil a 4-pole RCCB in your main distribution board (Fuse box) for safety.
