Does Buried Electrical Wire Need To Be In Conduit

By | August 11, 2022



In construction, buried electrical wire is one of the most effective ways to safely bring power to where it’s needed. This is because underground wires are protected from damage and weathering. But even though electrical wires that are buried in the ground are more secure than those installed above ground, there can still be potential safety issues if they are not installed properly. The question of whether they should be enclosed in conduit often arises.

When considering whether buried electrical wire needs to be in conduit, there are a few things to keep in mind. First of all, there are certain applications in which conduit is required by law, such as when wiring for refrigeration systems, water heaters, and swimming pools. Additionally, some local codes stipulate that any wiring buried in the ground must be installed in conduit regardless of the application. Furthermore, certain direct burial cables are made specifically to be installed without conduit.

For the most part, the decision of whether to install conduit ultimately comes down to preference. PVC conduit can provide good protection from water, heat, and other environmental factors. It is also relatively inexpensive and easy to install. On the other hand, direct burial cables offer a viable, albeit slightly less secure, alternative.

No matter what type of system you choose, it is important to ensure that it is correctly installed and up to code. This means using the right type and size of wire and conduit, and making sure that all wiring is done in accordance with the National Electric Code. Proper installation is essential for ensuring the safety and longevity of your system.
