Avoid substandard or counterfeit materials at all costs.
4. Ensure Proper Earthing for Complete Protection
Earthing is vital to prevent electric shock, equipment damage, and fire hazards.
Checklist for proper earthing:
All distribution boards, switches, and appliances must be earthed.
Always use three pin plugs for appliances.
Ensure earthing is done using approved electrodes and verified by a licensed electrician.
5. Follow Best Practices During Installation
Professional installation ensures long-term safety and hassle-free maintenance.
Best practices include:
Use ISI-marked conduit pipes (20–25 mm).
Medium-duty pipes for concrete
Light-duty pipes for blockwork
Avoid wire joints; if unavoidable outdoors, use weatherproof junction boxes.
Place the main switchboard near the entry point.
Install a distribution board (DB) on each floor for ease of control.
Keep communication cables (TV, internet, telephone) in separate conduits to avoid interference.
Never overload sockets; avoid “octopus connections.”
6. Inspection, Testing & Certification
On completion of wiring:
The licensed contractor must issue a Completion Certificate.
The KSEB must approve the wiring before energisation.
KSEB requires proper documentation and safety certificates prior to providing the connection.
This ensures the system has been tested and meets all safety norms.
7. Everyday Electrical Safety Tips for Households
Never touch switches or appliances with wet hands.
Ensure no exposed wires are left unattended.
Wear rubber footwear while handling electrical devices.
Turn off the main supply during a short circuit.
Educate children on electrical hazards.
If your house wiring is older than 25 years, get it inspected immediately old wiring may not support modern loads.
