Sub- Panel in barn

[A.B.C.E]

Can not remember in the 2008 NEC the requirements for grounding of a barn with metal siding, where livestock is present. We are putting a sub-panel in the barn and the barn has metal siding.

250.32 will help you with the requirements for grounding/bonding for a detached structure. You may also want to visit article 547. In particular 547.10
