2.2.10 Lightning Protector Installation

Overview
A lightning protector is a device that must be installed on a CO line to prevent a dangerous
surge from entering the building and damaging equipment.
A dangerous surge can occur if a telephone line comes in contact with a power line. Trouble
due to lightning surges has been showing a steady increase with the development of electronic
equipment.
In many countries, there are regulations requiring the installation of lightning protection. A
lightning strike to a telephone cable which is 10 m (33 ft) above ground can be as high as 200
000 V.
The PBX must be installed with lightning protectors. In addition, grounding (connection to
earth) is very important for the protection of the user.
Be sure to comply with applicable local regulations (e.g., law, guidelines).
