How far can you run electrical wire underground?
The distance you can run electrical wire underground is determined by several factors, such as the type of cable used and the voltage of the wire in use. According to the National Electrical Code (NEC), the depth of burial should never be less than 18 inches, and the insulated wires in the conduit must not come into contact with any combustible material (trees, shrubs, etc.
). Depending on the type of cable used and the voltage of the wiring, it may be allowed to be buried at a depth of up to 48 inches. When higher voltages are in use, the conduit must be encased in concrete.
If the conduit for carrying wires is metal, it is important to keep the wiring separate from other underground metal conduits (i. e. , water and other utility lines) due to the possibility of induction.
If the wiring is run in a plastic conduit, it can follow the same path as existing lines, but the wiring must never come in contact with combustible material. The amount of grounding protection must be discussed with a licensed electrician.
In certain circumstances, when cables are buried at an even greater depth, it may be necessary to use intermediate whips or pull boxes to reinforce the system. This prevents unnecessary friction dragging on the cables and helps to increase the protection afforded to the wires against the elements.
Ultimately, it is best to consult with a licensed electrician to determine the correct code and safety requirements for your particular situation.
What kind of electrical wire can be buried underground without conduit?
Underground cable, also known as direct burial (DB) cable, is specifically designed for usage buried underground without the need for conduit to protect it. This is accomplished through the utilization of waterproofing compounds and robust materials.
Direct burial cable can be used for low voltage applications up to 600V, and typically consists of copper core insulated with polyethylene or cross-linked polyethylene. The copper wire can either be solid or stranded.
Additionally, direct burial cable often includes a grounding conductor. To ensure a long life, cables should be buried 12 – 24 inches below grade to ensure protection from surface activities and provide adequate insulation from water seepage.
Regardless of the type of wire used in an underground application, a good practice is to install warning tape on the surface above any type of wiring. The tape should indicate that wiring is below, warning incidental excavation workers or anyone else that may be working in the area.
