Exterior Lighting Cable and Wire FAQs

Does low-voltage lighting wire go above or under the ground?

Low-voltage wire can be installed both above and underground. Burying the wire is often preferred for a cleaner look and added protection from inclement weather. One con of burying wires is that detecting and repairing damage can be more difficult.

Can I use low-voltage wire for line voltage applications?

No, low-voltage wire is not suitable for line voltage applications. Our low-voltage lighting wires are equipped to handle your 30-volt or lower lights reliably and safely. Each spool includes exterior lighting wire or cable that is sunlight resistant and comes with essential mounting accessories for easy installation—everything you need to make setting up your landscape lighting as effortless as the flick of a switch.

How do I protect lighting wire from the elements?

Our exterior lighting wire options are rated for outdoor use. To further safeguard from the elements and round out your waterproof landscape lighting setup, consider additional protective measures like conduits, electrical tape, or burying the wire to shield it from environmental damage and keep it in working condition.

Is special installation required for low-voltage lighting wire?

Our low-voltage wire is easy to install with basic tools. Follow manufacturer spacing, connections, and safety guidelines. Make a comprehensive plan before installation or consult a professional if you require assistance. Choose from our durable, high-performance, low-voltage outdoor lighting wire and cable solutions to bring your favorite spaces to light.

How often should I conduct maintenance on landscape lighting wire?

Lighting maintenance should always involve an inspection of outdoor light wires. If you live in a place where you experience seasonal changes year-round, you should be inspecting in between seasons. Look for exposed wires, a dangerous electrical hazard for you and your lighting system. In addition, some wires might be slowly coming back up to the surface due to inclement weather and erosion. Make sure to rebury these wires to prevent small problems from turning into massive headaches.

What gauge works best for my outdoor light wire setup?

Most systems will utilize a 12/2 wire. However, larger outdoor lighting setups that cover more square footage might need a larger gauge wire, such as 10/2 or even 8/2. However, these are more expensive due to the amount of copper used in order to reduce the chances of a voltage drop over larger distances.

How do I connect low-voltage wire to fixtures?

Use waterproof connectors to join the low-voltage wire to your lighting fixtures. Strip the wire ends, insert them into the connector, and secure them tightly for a reliable connection. Read our Lighting Academy guide on installation for the step-by-step procedure.
