But all incoming services, water, cable, tv aerials, ham radio antennas, cab antennas, telephone services, etc... are required to be bonded to the main grounding electrode, or if too far from there, to the nearest electrode location that is bonded to the main electrode by bonding jumpers of at least 8 guage wire between electrodes...
there is a similar code 8n the UK, that has just been changed to say that if the service comes into the property in an insulated pipe, such as gas in plastic pipe, water in pvc pipe, etc, then you do not need to bond these to the grounding system as they will not bring in transients or allow faults from your property to cause problems elsewhere in the services... this is in the bonding and grounding sections..,
or have I misunderstood all the YouTube videos and other items on grounding and bonding? Which is not just for lightning protection, although it helps stop the problems caused by having ground rods not bonded to each other.. equipotential bonding...
but also to send any faults introduced within your residence to ground rather than allowing them to continue to a neighbors home and damage their belongings... if your water pipes are not bonded to ground and a short in your place causes your pipes to be carrying line voltage, and your neighbor also has not bonded their pipes... and the water pipes between the two places are metal... then your short circuit could electrocute your neighbor..
not that common.., but has happened apparently in apartments or townhouses...
