I'm helping out a friend with a new house who wants to add surge

ground? *There are actually two 150 amp panels next to each other.
The service comes into a long narrow metal box between the two panels,

copper ground wire that runs from this narrow metal box into the
concrete basement slab. * So, what is the correct, code compliant

Can I buy some type of bolt on connector that I can slip over the
exposed existing ground wire outside the box and secure another ground
wire to it and then run over to the coax protector? *That would seem
to me to be the preferred method, if permissible.

Or can I bond to the ground inside one of the breaker panels and run a
ground wire from the panel out to the coax protector?

If I was doing it, I would just use a split bolt as others have
suggested. You want to minimize wire length to the common connection point.
