how to splice low voltage landscape lighting wire


Landscape lighting is one of the best ways to add beauty and highlight features around your home. You can call experts and technicians to fulfill the job. But if you have decided to give it a hand, go through our article on how to splice low voltage landscape lighting wire.

The lighting system and connectors often come in kits with precuts lengths of wire. Most people have a small yard and don’t create much difference. But for the larger yard you may need to know how to splice low-voltage landscape-lighting wire.

Whether you are adding new lights to your existing landscape system or re-wiring to change the circuit from series to parallel, splicing your outdoor wiring is crucial.

How to splice low-voltage landscape lighting wire is not a difficult task. With some simple tools and your knowledge, everything is handy.

  • Safety is your priority, and for this, it’s vital to disconnect your lighting from the power. Some people think they are dealing with low-voltage wiring and forget to disconnect the power.
  • For this project, you need wire cutters and strippers, soldering iron, connectors, wires, and heat-shrinking tubes.
  • The next step in how to splice low voltage landscape lighting wire is your method of splicing. There are two options. Either solder the wires together or use a dedicated wire connector. Let’s talk about them one by one.

For this process, Get twist-on wire connectors for ordinary household wiring splices. Disconnect the power and install a connecting box. Insert the cables through the holes. Now strip 1 inch of insulation off the wires for connecting and twist the wires with matching colors of insulation.

After connecting the wires, wrap the connector and the connected wire via electrical tape. Now place the wires in the connecting box and tighten it. The last step follows screwing the lid.

After disconnecting the power, start preparing the wire by cutting the length you need from the roll of the wire. Now separate the leads on both the wires from the ends you need to splice.

Slip at least three-inches length of shrink tubing over one wore of each splice. Now, twist the wires( wires of the same polarity) horizontally so that the twisted portion is in line with the wiring. It’s time to solder the connection! Use a hot soldering iron to the twisted leads and when the twisted wire gets heated, apply the solder to the wire, allowing it to melt for stronger joints. Now remove the soldering iron and keep repeating the process with the other set of twisted leads.

After completing the soldering process, let the meal cool. Once the metal has cooled, smoothly slip up the heat-shrink tube to cover the freshly joined leads. Use the hair dryer.

Once the tubing has shrunk tightly over the joint, repeat for the other lead. It’s time to light up your yard! Plug in your system, return power, and test your lighting system.

The next crucial question is how to splice Low Voltage Landscape Lighting Wire should you splice the wire in parallel or in series?

Connecting wires in series mean one continuous loop, while parallel circuits are a series of circuit loops wired in parallel.

Considering safety as the priority, you should aim to splice the wire in parallel series. The reason for choosing this is –

If any part of the circuit gets damaged on a series circuit, the entire circuit will get affected.

Secondly, if a light blows out in the series circuit, every single light bulb will stop working as the entire look has lost the connection.

Thirdly, there is a negligible chance of voltage drop.

Terminating low voltage landscape lighting wire is quite simple.

All you have to take care of is preventing moisture damage to the system. You need the following things-

  •   Low-voltage cable designed for landscape lighting
  •   Wire cutters and strippers
  •   Electrical tape
  •   Dielectric grease
  1.   Use cable caps that come with the in-lite transformer.

  2.   Simply split your wire a little and slide the cable caps down the end of the mainline cable.

Take cables caps and cover the wires from the Upper portion separately.

If you are out of caps, use dielectric grease and electrical tape. Split the cable down the middle to separate the two copper sides. Now, cut one of the sides shorter.

Add a small amount of dielectric grease( available at your local hardware store) and wrap it with electrical tape.

Remember to ensure that the system is s installed smoothly and correctly so that things will continue working well into the future.

Installing good quality fixtures, a good lighting design plan, and another trick, installing low-voltage lighting is a piece of cake.

Splicing a landscape wire lighting Wire is not a tough row to hoe even if you haven’t soldered before. Just follow few tricks and you are good to go!

  •  The aim is to have a waterproof seal and protect the spliced section. Don’t expose your copper wire to moisture. By doing this, you can damage the lights or cause short-circuit.
  • Moisture is the biggest enemy of the wiring system. Even a tiny drop of moisture can change and wipe out the circuit. Always use 100% waterproof materials. Whether installing a new system or terminating it, check out the materials and its characteristics.
  • Always check your connections and wiring system before installation. If you felt like they need a replacement, go for it!

That’s all for splicing low voltage Landscape Lighting Wire! Be careful while setting up the connection ,and wear gloves and specs for precautions.
