1. Understand the Lighting System
- Aquascape Warm White two wire lighting can be spliced. The Color Changing Lighting can not.
- Splicing is often done when:
- Extending the wire length.
- Repairing a damaged wire.
- Branching off to connect multiple lights.
2. Use Proper Tools and Materials
- Waterproof Wire Connectors (e.g., silicone-filled or gel-filled wire nuts).
- Heat Shrink Tubing for insulation and waterproofing.
- Wire Strippers for clean removal of wire sheathing.
- Low-Voltage Cable (ensure the gauge matches the original wire, typically 16/2 or 18/2).
- Electrical Tape (optional for additional sealing).
3. Safety Precautions
- Turn Off Power: Ensure the transformer supplying power to the lighting system is turned off or unplugged before starting work.
- Verify Compatibility: Always use materials and connectors rated for outdoor and low-voltage lighting systems.
4. Splicing Process
A. Strip the Wires
- Use the wire stripper to remove about 3/4 inch (2 cm) of insulation from each wire end to expose clean copper.
B. Connect the Wires
- Match the corresponding wires (positive-to-positive and negative-to-negative). Typically, low-voltage cables have a smooth or ribbed side to indicate polarity.
C. Use Waterproof Connectors
- Option 1: Gel-Filled Connectors
- Insert the stripped wires into the waterproof gel-filled wire connector.
- Twist to secure the wires inside the connector. The gel will protect against moisture.
- Option 2: Heat Shrink Tubing
- Slide the heat shrink tubing onto one wire before splicing.
- Twist the corresponding wires together securely.
- Slide the heat shrink tubing over the splice.
- Use a heat gun or lighter to shrink the tubing, ensuring a watertight seal.
D. Insulate Further (if needed)
- For added durability, you can wrap the splice with electrical tape, especially if it will be buried or submerged.
5. Test the Connection
- Turn the transformer back on and test the lights to ensure:
- Proper operation.
- No flickering or dimming, which can indicate a poor connection.
6. Waterproofing and Burial
- Waterproofing is critical: Even though low-voltage systems are safe, water infiltration can cause corrosion or connection failure over time.
- If burying the spliced wire, use direct burial-rated wire and ensure the splice is properly sealed.
Important Notes
- Wire Gauge: Always use the same gauge (e.g., 16/2 AWG) as the original wiring to avoid voltage drop or overheating.
- Voltage Drop: If extending wires over long distances, consider using thicker wire (lower gauge, e.g., 14 AWG) to reduce voltage drop.
- Warranty: Splicing may affect product warranties. If the splice is done poorly, it may affect warranty
By following these guidelines, you can safely splice Aquascape low-voltage lighting and maintain system integrity. If you are uncertain, consult with a professional electrician or Aquascape support.
