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 double Pole Fixed RCD?
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.
