Low Voltage Landscape Lighting Wiring Basics
Follow Manufacturer Instructions
Always read and follow the instructions provided by the light fixture manufacturer. The ultimate authority is the National Fire Protection Association (NFPA), which is the federal authority on electrical safety. The NFPA offers free web-based access to the National Electrical Code (NEC). Regulations relating to landscape lighting are located in Chapter 4, Article 410.Visit the NFPA Website
Always use as few connections as possible when connecting lights to the system. All connections made should be considered permanent to ensure a long-lasting, trouble-free installation.
It is highly recommended against the use of standard wire nuts or connection blocks, as these are NOT considered permanent connections; they are both openly exposed to the environment, allowing moisture and dirt around the wire. This WILL fail eventually, causing intermittent problems that are troublesome to identify.A crimping type connection with dielectric grease is an excellent, long-term solution. Soldered connections with "grease caps" (dielectric grease-filled wire nuts) are also a great long-term solution. These types of connections are protected against water and dirt by use of the dielectric grease.
Always adhere to local and National Electric Code regulations.
