IEC 62305-3 outlines how to prevent these hazards through physical insulation (covering down-conductors with cross-linked polyethylene), physical barriers (fencing off down-conductor zones), or grounding mesh grids that equalize surface voltage. 6. Maintenance and Inspection
Designing an External Lightning Protection System (LPS) to intercept direct strikes.

Establishing safety protocols to protect living beings from touch and step voltages. External Lightning Protection Systems (LPS)
Down-conductors must be insulated with high-dielectric materials (such as cross-linked polyethylene) or physically cross-bracketed out of human reach. IEC 62305-3 outlines how to prevent these hazards
Safely routes the captured current from the roof to the ground. Earth-termination system:

: Ensuring separation distances between the LPS and other conductive parts. East Coast Lightning Equipment Technical Specifics Lightning Protection Levels (LPL)
) must be maintained between the LPS conductors and the internal metal parts. The standard provides formulas to calculate this distance based on the material insulation properties and the path length of the current. Materials and Dimensions
Used primarily for simple structures or vertical rods. The protective angle ( ) varies based on the height of the rod and the chosen LPL. 2. Down-Conductor System
