1. Safety Precautions:
- Turn off the power supply or the corresponding circuit breaker to ensure safety before starting any electrical work.
2. Prepare the Switch:
- Remove the cover plate of the switch to expose the terminals.
3. Identify Terminals:
- Double pole switches typically have four terminals:
- Live Terminal (L): Usually colored red or brown, this receives power from the power source.
- Neutral Terminal (N): Usually colored black or blue, this connects to the neutral wire.
- Switched Live Terminals (L1 and L2): These carry power to the connected devices when the switch is turned on.
4. Wire Connection (Using Color Codes):
- Connect the live wire (red/brown) to the "L" terminal of the switch.
- Connect the neutral wire (black/blue) to the "N" terminal of the switch.
- Connect the two switched live wires (often colored black or red) to the "L1" and "L2" terminals of the switch, respectively.
- Note that the color codes may vary based on the country and wiring regulations, so always double-check the local electrical codes for the correct wiring colors.
5. Terminal Tightening:
- Tighten all terminal screws securely to ensure proper electrical contact.
6. Final Check:
- Make sure all wires are securely connected to their designated terminals.
- Ensure no loose wires or exposed metal parts are present.
7. Restore Power:
- Turn on the power supply or the corresponding circuit breaker to provide electricity to the switch.
8. Test the Switch:
- Flip the switch to verify that the connected devices are functioning correctly.
Note:
- Before working on electrical circuits, check with local regulations and electrical codes. Additionally, if you're unsure about any electrical work, it's best to consult a licensed electrician to ensure safety and compliance with electrical standards.
