How long should the grounding rod be buried?

there is no specified standard for how long the grounding rod should be buried, and its buried length should be judged according to the actual situation.

according to its grounding state, its depth and its level. The depth is also different. Because of this, the whole process of grounding rod should not be less than 24 cm, which is 24 cm. Unless the grounding rod can reach a suitable protection device when it is installed, the upper end of the grounding rod should be horizontal or lower than the ground. If you want to reduce his ground resistance, you need longer grounding rods, and some people will use more than two grounding rods. It must be noted here that the distance between the grounding rod and the grounding rod cannot be less than 18 cm. In the process of using it, firstly, some soft copper wires should be selected according to the voltage level of the grounding rod, and it is necessary to determine the position without any deviation, so as to ensure its own safety.
