Always start by identifying each conductor clearly. The live wire is usually brown, the neutral wire blue, and the earth wire green with a yellow stripe. Confirm these colors before making any connections to prevent short circuits or electric shocks.
Ensure the cord grip is secured firmly. This prevents strain on the terminals and keeps the contacts from loosening over time. Use a screwdriver to tighten screws without over-torquing, as stripping may damage the connector.
Insert each wire into its designated terminal carefully. The live wire goes to the right-hand terminal, neutral to the left, and earth to the top. Make sure no copper strands are exposed outside the metal clamps, as this increases the risk of sparking or accidental contact.
After assembly, test the connection before plugging into the mains. A continuity tester or multimeter can verify that all conductors are properly connected and that there are no shorts between terminals. Correct alignment ensures long-term safety and reliable operation of devices.

Start by stripping the outer sheath carefully. Expose about 10mm of each conductor without nicking the copper strands. Insert the live wire into the right-hand terminal, neutral into the left, and earth into the top. Ensure the metal clamps fully cover the exposed strands to prevent accidental contact or sparking. Tighten screws firmly but avoid over-tightening, which can deform terminals and reduce conductivity.
Secure the cord with the grip before testing. Once all conductors are in place, use a continuity tester to verify proper connections. Check that no strands touch adjacent terminals and that the earth connection is intact. This ensures the assembly is safe for repeated use and minimizes the risk of electric faults or overheating during operation.
Identifying Wires and Their Correct Terminals
Check the color codes carefully before making connections. Brown indicates the live conductor, blue is neutral, and green with a yellow stripe represents the earth. Confirm each color against the cord markings to avoid incorrect placement.
Use a small continuity tester to verify which conductor is live. Touch one probe to the exposed end of the suspected live wire and the other to the metallic terminal of the power source. A positive reading confirms the correct identification, preventing misconnection.
Keep the copper strands twisted tightly before inserting into terminals. Loose strands can create short circuits or poor contact. Trim any frayed ends and ensure no bare metal extends outside the clamps.
Mark each conductor with temporary labels if needed. This is particularly helpful when multiple cords are prepared simultaneously. Labeling reduces confusion and ensures each conductor goes to its designated terminal accurately.
Align each conductor with the terminal slot properly. The live conductor connects to the right-hand slot, neutral to the left-hand slot, and earth to the top slot. Make sure the metal clamp grips the insulation just enough to hold the cord securely without crushing it.
After placement, tighten each screw gradually while checking that the conductors remain seated correctly. Test the connections with a multimeter to ensure continuity and isolation between conductors. This prevents accidental shorts and guarantees safe operation of the device.
