Section 7. Installation

In addition to protections discussed in ESD Protection (p. 86), use of a simple
lightning rod and low-resistance path to earth ground is adequate protection in
many installations. A lightning rod serves two purposes. Primarily, it serves as a
preferred strike point. Secondarily, it dissipates charge, reducing the chance of a
lightning strike. Figure Lightning-Protection Scheme
(p. 89) shows a simple
lightning-protection scheme utilizing a lightning rod, metal mast, heavy-gage
ground wire, and ground rod to direct damaging current away from the CR800.
