Wylex Spd Wiring Diagram. A higher energy spd is used between neutral and the protective conductor. Boards circuit breakers wiring systems and equipment for industrial use stationary motors with permanent connection to the fixed installation.

This higher energy spd typically a spark gap for a type 1 spd is required as lightning currents arise towards the protective conductor and as such this higher energy spd sees up to 4 times the surge current of the spds connected between the live conductors. The conductors used to connect the spd to the line or bus shall not be any longer than necessary and shall avoid unnecessary bends green wire the following represents a wiring diagram of spds in a typical system. This also follows the lpz or lightning protection zone concept of breaking down.
This also follows the lpz or lightning protection zone concept of breaking down.
Spd performance is a function of the connecting lead length. This higher energy spd typically a spark gap for a type 1 spd is required as lightning currents arise towards the protective conductor and as such this higher energy spd sees up to 4 times the surge current of the spds connected between the live conductors. This also follows the lpz or lightning protection zone concept of breaking down. Can anybody confirm the connections to this as it is placed within the fuseboard upstream of the main switch.
