Electric lines are typically buried at varying depths depending on their voltage and local regulations:
- Most residential electric lines are buried between 24 inches (2 feet) and 48 inches (4 feet) deep, with 24 inches being common for standard service lines
- Low voltage lines, such as those for pathway lighting or landscape lighting under 30 volts, are often buried much shallower, around 6 inches or even just 1 to 2 inches deep
- High voltage cables (above 22,000 volts) are buried deeper, usually at least 36 inches (3 feet) and sometimes 42 inches or more for very high voltage lines
- Some underground power lines can be buried even deeper depending on site conditions; examples include lines buried 2.5 to 3 feet deep or even as deep as 5.5 feet in certain cases
- Electrical lines are often installed within conduit and must be buried at least 24 inches deep, with a warning ribbon placed about 12 inches above the line for safety
Before digging, it is legally required and strongly advised to call 811 or your local utility marking service to identify exact locations and depths of underground electrical lines to avoid damage and hazards
. In summary, typical burial depths for electric lines range from about 2 feet for standard residential lines up to 3 feet or more for high voltage lines, with low voltage lines buried much shallower. Depths can vary based on local codes, voltage, and terrain.
