Typical House Lightning Protection Installation Procedure
(Study this diagram one section at a time.)

If possible, place one Ground Rod near the electric service ground and make a connection to the ground wire - use Multi-purpose clamp and a short piece of wire. You can make a small trench and bury the wire.

If you have a cupola with a weathervane, you need a bolted clamp and a short piece of cable; make a connection to the vane pole. If no vane, install a Rod on top of the cupola.

AIR TERMINALS Rear view of roof ridge showing course of conductor and air terminal on back side. Only slender point is visible from front of home.		SEMI-CONCEALED CABLES Conductor cables are semi-concealed on back side of ridges and on facer board (a) at end of house.

Ground Rod is easily driven in with a heavy hammer or you can bury a ground plate instead of a ground rod.

GENERAL DESIGN RULES

All buildings must have two groundings as widely separated as possible, preferably at diagonally opposite corners if perimeter, distance around, is 250 feet or less.

If building perimeter is between 250 feet and 350 feet, then three groundings are required. If between 350 feet and 450 feet, then four groundings, etc.

Lightning Protection Systems shall be applied to metal covered buildings in like manner as on buildings without metal coverings.

Cables shall be free of sharp turns and "u" or "v" pockets. Cables shall maintain a horizontal or downward course.
