    I'm rewiring my home for digital cable. I see that the cable company has ran a ground wire frome the outside box all the way around my house to the power meter's ground. Is there a reason for this? wouldn't it be easier to just ground it directly beneath the cable box? Thanks

    just being curious why is that? I understand its code. But what repercussions are there for not doing so? I'm not going to change it, but I always like the technical reason. Thanks

    To avoid a "gound loop" : a potential difference between 2 grounds.

    You CAN ground to a rod directly beneath the cable box, but you should also run the ground wire to the house ground.

    MY cable installer grounded to the water faucet 3 feet away from the cable box, not bothering to check that the water pipe going to it was PVC. [​IMG]

    That has since been corrected.
