When selecting electrical wiring for outdoor applications, selecting the appropriate cable type is essential to guarantee safety and long-term success. Outdoor electrical cables must withstand extreme temperatures, moisture exposure, and UV rays. This article will look at various types of outdoor-friendly electrical wires.
Underground Feeder (UF) Cable
An underground feeder (UF) cable is an electrical cable commonly used for outdoor wiring. UF cable has been designed for direct burial in the ground and can withstand moisture, sunlight, and temperature changes.
The outer jacket of UF cable is composed of PVC, which offers excellent resistance against these elements and abrasion. Moreover, its conductors are formed of solid or stranded copper, which makes it a superb conductor of electricity.
Thermoplastic High Water-Resistant Nylon (THWN) cable is an outdoor electrical cable designed to withstand moisture and temperature changes.
THWN cable often finds application in outdoor lighting and irrigation systems due to its PVC outer jacket, which offers excellent resistance against weather elements like sunlight. Inside, the conductors are constructed out of solid or stranded copper, a great conductor of electricity.
Metal-Clad (MC) Cable
Metal-Clad (MC) cable is an electrical cable commonly used outdoors. MC cable features a metal jacket to protect it against moisture, sunlight, and abrasion. The conductors are made of solid or stranded copper – an excellent conductor of electricity. MC cable finds use in outdoor lighting, air conditioning, and other outdoor applications that need extra protection against weather elements.
Underground Service Entrance (USE) Cable
Underground Service Entrance (USE) cable is an electrical cable commonly used outdoors for direct burial in the ground. USE cable’s outer jacket, made of PVC, provides excellent resistance against moisture, sunlight, and abrasion. In contrast, its conductors are made of solid or stranded aluminum, making it a good conductor of electricity. USE Cable
Underground Service Entrance (USE) cable offers excellent outdoor performance due to its direct burial design and can withstand temperature changes.
Non-Metallic (NM) cable is an excellent option for outdoor applications. NMB cable has a PVC outer jacket which provides excellent resistance against moisture and sunlight, while its conductors are made of solid or stranded copper – an excellent conductor of electricity.
How to Protect Outdoor Cables?
As was mentioned previously, there are a variety of external threats that can cause a lot of harm to cable. If you’re using something other than high-end outdoor cables, it is necessary to protect your cables, and there are many ways of safeguarding outdoor wires.
However, the most straightforward and efficient alternative is to stay clear of cables needing extra security. There are a variety of outdoor wires that can stand up to any external stress without reinforcement, and this cable costs far more expensive than regular outdoor cables.
Rest assured that a strong cable enough to resist any external limb is worth the investment. Additionally, you can pay less for additional security.
Selecting the appropriate cable type for outdoor applications is paramount when selecting electrical wiring for outdoor applications. Outdoor cables must withstand extreme temperatures, moisture, and UV exposure without fail. UF cable, THWN cable, MC cable, USE cable, or NMB cable are all excellent choices depending on your requirements. Be sure to consult a licensed electrician to determine which type of cable best meets your outdoor wiring demands.
