NEC 110.31 specifies that fences around high voltage equipment need to be 7' high, or 6' + 1' of barbed wire. Unlike pool fencing, it's not very specific about maximum gaps, particularly at the bottom. I'm inclined to say a 6' chain link fence with a 1' gap at the bottom would be permissible- anyone else have strong opinions?
As we dedicate large areas of land across the country to these solar farms, I'd really like to see the NEC consider the fact that these fences are now being applied to much larger areas than your typical substation. I don't see why we shouldn't allow for small gaps at the bottom to promote the movement of small animals... no need to take away their habitats entirely, right?
