Re: Lighting gorund into ac?
ephesus56ad, the point everyone here is trying to make is you can install as many ground rods as you wish. You can have one for each service such as CATV, AC service, Satellite, antenna tower, phone etc. But they all have to be bonded together (preferable under ground) to form a single electrode system.. If you fail to do this you would use earth as a conductor for a fault path. The earth is not capable of doing this. The result is extremely high voltages will develop between system during a fault condition that will damage equipment, create a fire hazard, and personal injury.
As a GC if you have any influence on initial construction you should encourage the designers to bring all services (gas, water, electric, phone, cable, antennas, etc) into the facility at one point. A window if you will. This allows for simplicity of bonding the services, offers the greatest amount of protection and operation flexibility. You can bring them in from all sides, but if you do this you would need a ground ring to bond all of them properly.
So I must agree with the members you should use a licensed professional who understands the risk and dangers (and is bonded & insured). I would hate to see you injure someone or damage property by trying to do it yourself . I think you know what the legal implications are.
Good Luck
