Splicing low voltage landscape wire is generally considered acceptable, as long as proper precautions are taken. Here are some key things to consider when splicing these wires:

Safety Precautions
Anytime you are working with electrical wires, even low voltage, safety should be the top priority. Be sure to:
- Turn off power before splicing wires
- Use insulated tools and gloves when handling exposed wires
- Avoid working in wet conditions
Choosing a Splice Location
Select a splice location that will be protected from moisture and mechanical damage. Avoid splicing wires in areas where they may be subject to:
- Direct burial underground
- Exposure to sunlight and water
- Abrasion from rocks or other landscape materials
The best locations are often near the fixtures, inside watertight junction boxes.
Using the Proper Connectors
Using the right type of connectors is critical for a reliable splice:
- Use connectors rated for direct burial when needed
- Select connectors that form a watertight seal
- Choose connectors sized for the gauge of the wires being spliced
- Avoid cheap plastic twist-on connectors – use gel-filled or epoxy splice kits for best results
Recommended Connectors
| Connector Type | Description |
|---|---|
| Gel-filled splice kits | These are easy to use, form a water-resistant seal, and protect against corrosion. |
| Epoxy splice kits | When mixed, the epoxy hardens to encase the wires in a durable, waterproof bond. |
| Grease caps | Plastic caps are filled with silicone grease to displace moisture and prevent corrosion. |
Prepping and Connecting Wires
Proper technique when splicing wires is also very important:
- Strip wires using gentle scraping motion to avoid nicking or cutting wire strands
- Keep stripped ends twisted together tightly until inserted in connectors
- Make sure connector is sized correctly for wire gauge and number of conductors
- Follow manufacturer’s instructions to ensure proper use of connectors
It may also help to stagger the stripped ends when splicing multiple wires together. This reduces bulk inside the connector.
Testing Spliced Wires
Always test low voltage wires after splicing to confirm the connection:
- Use a multimeter or continuity tester to check for conductivity
- Tug gently on each wire to ensure there are no loose connections
- Turn power back on and test operation of lighting fixtures
Any issues can then be addressed before completing the project.
Conclusion
Splicing low voltage landscape wires is fine in most cases, provided proper precautions are taken. Choosing the right location, connectors, and technique will ensure reliable, long-lasting splices. Testing wires after splicing confirms that everything is in working order. Following basic electrical safety protocols is also a must when handling any exposed wiring.
