    I was just wondering if I needed another ground rod at my shed because of how far my shed is from the main ground rod at the house. House electricity.jpg

    Hello SETexas,

    Would not hurt for extra lightening protection.

    You can never have to many grounds, In Texas. The Deeper the better.

    Have a Great Day.

    P.S. Are You asking, about needing to meet electrical code ?

    The distance has nothing to do with it.
    If the shed has a sub-panel in it then it REQUIRES a grounding electrode. If it is only fed with a circuit then no ground rod is required, or needed IMO.

    In typical AC building wiring ground rods serve VERY little purpose.

    Yea, what he said.

    You can only have a single circuit in an outbuilding, UNLESS you have a subpanel in the outbuilding, which would then require grounding rods.

    As pointed out rods are required as well as an equipment grounding conductor installed with the feeders.
    Isolation of the neutral from the EGC and the grounding electrode conductor and panel enclosure.

    OK, subpanel you mean a breaker box? Yes I have a breaker box in shed fed from 100amp breaker in house.

    Although called a “subpanel” in the trade there is no such item as “subpanel”

    To be correct it is a remote distribution panel.

    Call it whatever trips your trigger but it will require a grounding electrode system

    And if your dirt is very dry, you may need two ground rods 10' apart.

    Most place will ask for two ground rods unless you get someone with specal tester to verify if the ground is under 25 ohms { that can get very expensive to do that } so it cheaper just get two ground rods and be done with it and keep the rods at least 2 meter apart { 6 feet } or more.

    Merci,.
