Does outdoor conduit need to be buried?

Answered by Randy McIntyre

Outdoor conduit does need to be buried in order to protect the wiring and ensure safety. When we talk about outdoor conduit, we are typically referring to electrical conduit that is used to protect and contain wiring that is installed outdoors, such as in gardens, yards, or other outdoor spaces.

Burying outdoor conduit serves several important purposes. First and foremost, it provides physical protection for the wiring, preventing it from being damaged by external factors such as weather, animals, or accidental contact. By burying the conduit, we ensure that the wiring is shielded from these potential hazards, reducing the risk of electrical accidents or damage.

In addition to providing protection, burying outdoor conduit also helps to maintain the aesthetics of the outdoor space. Having exposed wiring running across the ground can be unsightly and can detract from the overall appearance of the area. By burying the conduit, we are able to keep the wiring hidden from view, creating a cleaner and more aesthetically pleasing outdoor environment.

So, how deep should outdoor conduit be buried? According to electrical codes, low-voltage wiring must be buried at least 6 inches deep. This depth ensures that the wiring is adequately protected and reduces the risk of accidental damage. By burying the conduit at this depth, we can be confident that the wiring is safely contained and shielded from potential hazards.

It’s important to note that when the buried wiring transitions from underground to above ground, additional measures must be taken to protect it. At this point, the conduit must be extended above the required cover depth or 18 inches, whichever is greater, and continue in conduit until it reaches a termination point above ground. This termination point should be at least 8 feet above grade to ensure proper protection.

To achieve this, a transition fitting or conduit body is typically used to connect the underground conduit to the above-ground conduit. This helps to maintain the integrity and protection of the wiring as it transitions from the buried portion to the exposed portion. By using conduit for this transition, we can ensure that the wiring remains safe and secure, even as it emerges from the ground.

Outdoor conduit does need to be buried in order to protect the wiring and ensure safety. Burying the conduit at least 6 inches deep provides physical protection and helps to maintain the aesthetics of the outdoor space. When the buried wiring transitions from underground to above ground, it must be protected in conduit until it reaches a termination point at least 8 feet above grade. Following these guidelines will help to ensure that outdoor wiring is properly protected and meets electrical code requirements.
