3. Safety Information

Always prioritize safety when working with electrical components. Improper handling of electrical wire can result in electric shock, burns, or fire.

• Ensure power is disconnected before making or breaking any electrical connections.
• Use appropriate personal protective equipment (PPE), such as insulated gloves and safety glasses.
• Verify the wire's voltage and current ratings are suitable for your application.
• Inspect the wire for any damage (cuts, abrasions, exposed conductor) before each use. Do not use damaged wire.
• Consult a qualified electrician for complex installations or if you are unsure about any procedure.
• Adhere to all local electrical codes and regulations.

4. Setup and Installation

This test lead wire is designed for flexible test probes and high voltage apparatus. Proper setup ensures reliable performance and safety.

1. Preparation: Uncoil the required length of wire. Avoid kinks or sharp bends that could damage the insulation or conductor.
2. Stripping: Carefully strip the EPDM insulation from the ends of the wire using a wire stripper appropriate for 18 AWG wire. Ensure only the insulation is removed, leaving the tinned copper strands intact.
3. Connection: Connect the stripped wire ends to the appropriate terminals, connectors, or test probes. Ensure connections are secure and free from loose strands. For high voltage applications, ensure all connections are properly insulated and rated for the intended voltage.
4. Routing: Route the wire in a manner that prevents abrasion, pinching, or exposure to excessive heat or chemicals beyond its rated resistance.

5. Operating Guidelines

The NTE Electronics WTL18-02-50 wire is intended for use in electrical testing and high voltage applications.

• Always operate within the specified voltage (5000V) and current limits for 18 AWG wire.
• Avoid subjecting the wire to mechanical stress, such as excessive pulling or sharp bending, during operation.
• Ensure the wire is not exposed to temperatures outside its operational range, which could compromise insulation integrity.
• When used as test leads, ensure proper connection to test equipment and the circuit under test.

6. Maintenance and Storage

Proper maintenance and storage will extend the lifespan and ensure the continued safety of your test lead wire.

• Cleaning: If necessary, clean the wire with a damp cloth. Avoid harsh chemicals that could degrade the EPDM insulation, although it is resistant to many substances.
• Inspection: Regularly inspect the entire length of the wire for any signs of wear, cuts, cracks, or discoloration in the insulation. Pay close attention to areas near connectors or where the wire is frequently flexed.
• Storage: Store the wire coiled neatly in a dry, cool place, away from direct sunlight and extreme temperatures. Avoid storing it in environments with sharp objects or heavy items that could cause damage.
• Disposal: Dispose of damaged or worn-out wire according to local regulations for electrical waste.

7. Troubleshooting

This section addresses common issues that may arise during the use of electrical test lead wire.

• No Continuity:
  • Check for secure connections at both ends of the wire.
  • Inspect the wire for internal breaks or severe kinks.
  • Verify that the test equipment is functioning correctly.
• Insulation Damage:
  • If insulation is cut, cracked, or abraded, immediately discontinue use and replace the wire. Do not attempt to repair damaged insulation, especially in high voltage applications.
• Overheating:
  • Ensure the current flowing through the wire does not exceed the safe limits for 18 AWG wire.
  • Verify that the wire is not bundled too tightly or routed through areas with poor ventilation, which can lead to heat buildup.
