Electrical Codes adopted throughout North America carry the force of 
law. Virtually all include a requirement that all earth connections in a 
premises be bonded together, with certain exceptions for separate 
buildings. Lots on my website about that.

Over several years after moving in, I found some real horror stories in 
how this was not done in the home I bought when I moved here in 2005. 
Not even the craziest thing was that the required earth connection for 
the electrical service was to a nearby outlet for a garden hose, which 
was fed by PVC pipe.
