3-Phase Electrical Wiring Installation at Home
- First of all, connect the three-phase energy meter as shown in fig. ( if you don’t sure that how to wire a 3-phase energy meter, then check this simple method. How to wire a Three-Phase Energy Meter)
- Connect the MCCB (Moulded Case circuit Breaker) as main switch to the incoming three phases (R, Y, B) from 3-phase energy meter
- Now connect the outgoing phases (R, Y, B) from MCCB (Moulded Case circuit Breaker) to the DP (Double Pole MCB , RCD, SP (Single Pole MCBs and load) as shown in fig)
- Also connect the Neutral wires to RCDs and then to neutral links and then to specific loads (as shown in fig).
in USA and other Countries
L3 to N = 120 V
- Disconnect the power source before servicing, repairing or installing electrical equipments and installation.
- Also use the proper cable in size with this simple calculation method ( How to determine the suitable size of cable for Electrical Wiring Installation)
- Never try to work on electricity without proper guidance and care
- Work with electricity only in presence of those persons who has good knowledge and practical work to deal with electricity
- Read all instruction and cautions and follow them strictly.
