Procedure :
- Cut the Conduits in the required length (20cm) using Hack saw.
- Fix the conduits ,junction box ,switch box in required positions as per the lay out using saddles and screws.
- Run the wire through conduits, as per the given circuit diagram & then fix the Round block,switches,holder in required positions using screws.
- Check the circuit before applying the supply
- Give the single phase supply through a fuse and neutral link
- Check the conditions
