he home you have constructed should be electric shock proof. To achieve this, lots of precautions are required to be taken during wiring.  Therefore we advise to follow the best practices of the industry and follow the wiring rules laid down by Bureau of Indian Standards. Few of them are listed below for your guidance.
 1. Carry out wiring on distribution system
The wiring should be carried out on distribution systems with main and branch distribution boards to convenient centers. It is without isolated fuses. As far as possible all conductors should run along the walls and ceilings so that they are easily accessible for thorough inspection.
2. Don’t allow wiring to run above ceiling
In any case, the wiring should not run above ceiling. The circuit on opposite side of three wire systems or on different phases of three phase system is kept as far apart as possible in all cases and the minimum distance between two circuits should be 7 feet. Medium pressure wiring and all associated apparatus should comply with ISI specifications.
3. Don’t exceed the load on circuit
The number of points in light circuits should not exceed 10 or the total load on circuit should not exceed 800 watts. One circuit can be explained as one connection from electrical meter or from main fuse circuit. For power wiring circuit the number of points in a circuit should not be more than 2 and the size of wire should be 1.5 mm square for copper and 2 mm square for aluminum.
4. Fix switch boards at proper height
Switch boards should be fitted at a height of 1.5 meter. Horizontal run of wiring should be at a height of 3 meter.
5. Use earth wire of proper gauge
Earth wire should be 14 SWG in case of copper and 4 mm square in case of aluminum. Fuse wire should be connected to phase wire only and neutral link should be connected to neutral wire. Connect all switches in phase wire. Minimum size of earth wire for light circuit is 1 mm square for copper and 1.5 mm square for aluminum.
6. Make use of copper conductors
All conductors should be made of copper. They should have a cross section less than 0.0020 sq. inches, nominal area (3/0.029 inches) and every conductor should be stranded.
7. Never utilize damaged wiring or elements
Burnt element, cut/ broken wiring, loose/open connection and rusted points should never be used to avoid open circuit fault. Never make use of damaged insulation wiring to avoid short circuit fault. Damaged and loose connection should never be done in any appliance to avoid earth fault. Provide earthing to enhance voltage and protect human beings from sudden electric shock. You must fix lightening wire earth into the ground to protect building from cloud lightening.
