Secure Grounding Wire To Roof

Use a thick enough amount of adhesive so that the pulling load.

Secure grounding wire to roof.

It is standard industry practice to bond every section of rail to meet nec requirements. A metal roof doesn t change this. Ground that point if possible. Ground wires on each branch circuit throughout the house.

Otherwise you will cut the copper wire along with the shield forcing you to start over. Generally if you have a metal antenna mount on your roof that is over 5 feet tall you will want to ground that using a long copper wire. To attach the fixture to the roof shingles simply spread a generous glob of rtv adhesive over an area of about 2 1 2 inches in diameter. The best thing one can do to prevent stray rf is to connect the grounds of all equipment together and at a common point.

Work the adhesive against the shingles thoroughly so that it will bind well to the shingle. Line up the inner wire stripper with the copper wire in the middle of the foil shielding and slowly clamp the tool around the inner copper wire. Neutral wire normally carries return current in daily use gives flow path of current from source to earth. A copper rod driven into the ground with an antenna on the roof is especially not an rf ground.

Additionally if you have metal objects within a few feet of the roof itself such as metal structures on a nearby porch or large yard equipment you may consider grounding the roof as a safety precaution. If the mount is shorter or doesn t rise above the roof line then you can just use a surge arrester. Ensure that the copper wire ends up in the wire stripper when you close the tool. Also since the cable for the enphase contains a ground can that ground be wire nut tied to the array s ground wire and then to the grounding rod.

In many cases bonding can be done using existing utilities such as water pipes or meter boxes. The ground wire from service equipment to ground at water pipe or electrode s equipment grounding conductors.
