Cable While the terms wire and cable are often used interchangeably, technically wire is one electrical conductor and cable is a group of wires (or conductors), encased in sheathing. The nearer the radio room entrance panel and ground is to the electrical service entrance ground , and the lower bonding conductor resistance and impedance is compared to the impedance and distance of mains wiring to the radio in the house , the better this system will work! Proper grounding and bonding prevent unwanted voltage on non-current-carrying metal objects, such as tool and appliance casings, raceways, and enclosures, as well as facilitate the correct operation of overcurrent devices.

We have all heard of ground wires , and most of us have a vague idea that it may have something to do with the third arm sticking out of three-prong plugs.

The station ground and electrical mass of the tower and amateur antennas look like a much better ground than a typical small ground rod at the service entrance. The largest portion of surge flows through house wiring to station equipment, and eventually out to the low impedance antenna system (A) and station ground (B). The problem is my wiring in the house has no ground wire , just black and white.

I wired the ground wires from can light to can light. Do I need to attach a ground from all the cans to a screw in the stud or what?
