I walk by them close enough to touch all the time. Sometimes I do touch them.
I'm sitting on one having a snack right now.Heck, I sit on the little one feeding my house and 2 neighbors. It is located at the corner of my front lawn.
Depending on the voltage you may need more than three feet, but you can build it out of anything you want.ha I suppose I can use one as an out door desk! jk
Another question, I think it relvant.
I have dangerous rated panel close to pedestrians, I'm thinking about building a wall only( or do I need a room with roof) to make it a restricted area. would 3hr fire resistance stub walls do the job? based on what I read in the NEC I'll need min 3ft working space.

Wanna elaborate/clarify?
Yes you need working space, but I am in doubt that a barrier or room is needed. Possibly a sign stating clearances so it does not get blocked.
its 480V, indoor panel where a number of employees walk by it, I'd like to provide some kind of protection incase of Arc flash, fire so that no one is in direct danger.
So metal, wood, or an arc flash blanket are feasible options?
You can build a block wall if you want to , but I know of no NEC section requiring it.
Seriously, while your intentions are good IMO, it may be considered overkill. That panel is not going to flame up for no reason.
jado, is this panel like a 200A 480Y/277V panel used for lighting and such in a room or hallway?
its a 480y/277V 800A located by a hallway entrance, fed directly from 1500 KVA XF
I agree with Jumper. The chance of an arc incident are slim unless somebody has the doors open on the panel and is doing something.oh, I see your point,

I know someone who tried to run up and vault over a parking meter, with predictable results.
Precisely.
