![]() Related Post: Wiring of the Distribution Board with RCD (Residual Current Devices).At last, the ground wire from ground busbar has been connected to the ground terminal in SPA control box. the middle terminal is Neutral and the first and last one is two lines i.e. The same wiring can be done for 230V, 13A circuit using the correct wire size, proper circuit breaker rating and suitable rating of switches and outlets.Īs shown in the fig, the three output terminals has been connected to the SPA control box followed by the printed marking i.e. This way, this 15-16A, 120V outlet is GFCI protected by 20A GFCI breaker and it is recommended to use it in the watery areas like bathrooms, kitchen, spa and other outdoor applications. The ground terminal of outlet is connected to the ground bar in the mains distribution board. The GFCI breaker load neutral has been connected to the load terminal of outlet. The Line (Hot, Live or Phase) is directly connected to the GFCI input and the output is connected to the line terminal of ordinary outlet / receptacle. The builtin white wire in the ground fault circuit interrupter circuit breaker should be directly connected to the incoming supply neutral bar in the home mains distribution board or it will not work otherwise. The following wiring shows an ordinary outlet has been wired and protected through single phase single pole GFCI circuit breaker. ![]() Wiring a Single Pole GFCI Circuit Breaker Related Post: GFCI: Ground Fault Circuit Interrupter.Now, you have got the idea as we are going to show different wiring circuit diagrams for single pole, two poles, three poles and four poles (both single phase and three phase) RCD (RCCB) or GFCI circuit breakers. According to IEC and NEC, it is must to use and install these devices in watery areas like laundry, kitchen, spa, bathroom and other outdoor installation. GFCIs and RCDs are used to protect against electric shock in case of ground faults and leakage currents and trip the circuit. Related Post: Difference Between MCB, MCCB, ELCB & RCB (RCD or RCCB) Circuit Breakers.RCD may be defined as Current Operated ELCB which is known as RCCB.ĮLCB stands for “ Earth Leakage Circuit Breaker” and it has been replaced with the latest RCD device due to some of ELCB disadvantages (as it works on proper earth connection). RCD + MCB, then it is known as RCBO “ Residual Current Circuit Breaker with Overcurrent Protection“. In Europe and Australia, the same thing is known as RCD “Residual Current Interrupter” or RCCB “ Residual Current Circuit Breaker” or if overcurrent protection device such as MCB is used with combination of RCD i.e. In America, it is commonly known as GFCI “ Ground Fault Circuit Interrupter” or “ GFI “ Ground Fault Interrupter” or ALCI “ Appliance Leakage Current Interrupter“. RCCB is also known as “ Residual Current Circuit Breaker“.RCD is the short form of “ Residual Current Device“.GFCI is the abbreviation of “ Ground Fault Circuit Interrupter“.Wiring a Four Poles RCBO or GFCI Circuit Breaker (Three Phase RCCB Wiring). ![]()
