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.

This diagram will help you in almost any scenario. Your house will vary but just add the sections of you house that are not in this diagram and you should be able to plan your entire system with little or no help.

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.
