Drive-In Mag Anode
For low current requirement applications such as gas distribution risers, drive-in magnesium anodes are an economical choice. Anodes are manufactured from extruded magnesium rods, fitted with a special steel driving cap. The driving cap has been welded to the anode core with a #12 TW solid copper conductor wire attached by silver solder. The opposite end of the lead wire is soldered to a J-clip and hose clamp. A galvanized sheet metal contact screw pierces the pipe coating and provides connection to the structure. This connection will provide a positive, long-life contact. The wire connection at the anode is coated to prevent exposure of bare copper. The anode may be ordered without the clamp if desired.

Installation
-
Extend the coild lead wire with clip out from anode.
-
Select convenient location for the anode, a minimum of 18" from the service riser.
-
Drive the anode with a hammer into the earth to approximate depth of 4-6 inches.
-
Bury the anode lead wire from the anode to the riser at approximate 4-6 inch depth.
-
Place the clamp around the riser 8-10 inches above ground level and securely tighten with a screwdriver.
-
Tighten the set screw until it pierces the pipe coating and makes solid contact with the steel. Be certain the set screw head is fully secure against the J-clip speed nut.
-
Coat the screw connection with Scotchkote electrical coating or similar coating.
-
A pipe-to-soil potential measurement should be taken after connection to assure adequate cathodic protection is being achieved.
