Consumer and small commercial electrical lines must be buried between 6 and 24 inches underground, while large commercial and industrial lines must be buried between 30 and 36 feet underground. Electrical lines for carrying current to a home or building must be buried deep enough to avoid digging accidents by homeowners and others.
