does a detached garage with a subpanel and supply coming from the house need a lightening rod ? which gauge cable do you use to run a lightening rod to the ground ?

2 of them at least 6' apart and #6 copper.

thanks. any example diagram how i should put it all together ?

 

[amakarevic]

and also, how deep should i go burying the grounding ? is a couple feet ok ?

Just drive the 2 rods, run the #6 continuous through the 2 and land them on your ground bar in your panel.

I usually go through the first pulling enough to make it to the 2nd one and the rest back up in the panel.

If your talking about the ground wire between the 2 rods, I just take the claw of my hammer and dig a little trench just to have it underground or secure to the structure.

PS. Drive your rods flush with the ground, be sure to put the clamps on first because the ends flare out and you won't be able to get them on. Also, if it's getting inspected, I'd put some spray paint on the ends so the inspector can find them.

i am actually talking about a diagram that shows everything, the stick on top of the building and how it is connected to the subpanel and the rod that goes into the ground.

thanks, it does. so my only question left is should the cable from the air terminals run on the outside of the shed or the inside ? i would guess outside. if inside, my question is at which point does it go outside to go into the grounding rod ?

 

[wirenut1110]

I would say outside.
