Required Vehicle Clearance Distance from Substation Fence and Relevant Code References

[Golden State EE]

I am seeking clarification on the required clearance distance for vehicles, such as golf carts, maintenance trucks, and other equipment, from a substation fence. Specifically, I would like to know:

1. What is the minimum distance vehicles should be kept from the substation fence to ensure safety and compliance with regulations?
2. Are there distinctions based on the type of vehicle (e.g., light vehicles like golf carts versus larger trucks) or the voltage level of the substation?
3. Which sections of applicable codes or standards, such as the NESC, NEC or local utility regulations, provide specific guidance on this matter?
4. If anyone has experience or insights on this topic, including code references or best practices, I’d greatly appreciate your input! Thank you!

I'll confess I don't know exactly, but the general rule is that someone can do anything they like, within reason, on the other side of your fence as you have no powers or ability to stop them unless you own the land. The same applies to gas reception facilities - the hazardous area classifications need to be within the fenceline as there is very little you can do to stop anyone having a cigarette or a BBQ right against your fence if you don't own the land. Maybe not a great plan, but there are limts to the powers given to utility companies.

So basically make sure your fence is far enough away to prevent any issues.

You see substations right on the edge of busy main roads so I doubt you find what you're looking for in terms of regulations.

Guidance is a different thing and risks which are location dependant. So some might need vehicle barriers ( on your land) as added protection, but many won't.

Why are you asking?
