Well, here in Illinois, they apparently want it all bonded to the
electrical ground. However, in my house, the cable is grounded to a
ground rod in the earth. An August lightning storm really messed up
things in my house. The best we can tell, the current came in through
the ground, hit the cable abd Malibu lights. It took out the cable
company's coupler on the pedestal. It took out my cable modem, router
and computer. I think the ground potential on the cable and the ground
potential on the electrical ground were very different (because they are
ground to different places) and thus fried everything in between. So if
you have lightning, it is probably important. If you are in southern CA
were there is little lightning, it is probably not that important.

US Calif here. Do the wiring regs require that Cable and Telco services are
bonded to the electricity ground. It seems that my telco has it's own
ground (a wire disappears into the earth!), and the catv service is bonded
to an electrical conduit (but not the the ground stake itself). Any advise
for getting them changed to comply with wiring regs at no cost?
