Secondly, how do you bury a ground wire? Bury in the Ground: Dig 24 inches
- At 24-in.
- There's one restriction: It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground.
- Burying the cable 24 inches requires more digging, so this method only makes sense if you have easy-to-dig soil or are renting a trench digger.
Simply so, can bare copper ground wire be buried?
Stranded bare soft or annealed copper conductors are suitable for direct burial and do not suffer from the inherent corrosion problems that an aluminum conductor would. Copper is almost twice as conductive as aluminum. Copper is easier than aluminum to terminate and join at splices and joints.
