Which of the following is true when installing grounding conductors used for lightning protection?
Use only non-insulated wire
Wires must be carefully routed with precise right-angle bends
Sharp bends must be avoided✓Respuesta correcta
Common grounds must be avoided
Explicación
A lightning surge rises extremely fast, and a sharp bend adds inductance which develops a large voltage across it and can make the surge jump the corner to something else. Grounding conductors are therefore routed with gentle sweeping bends, and common bonding is required rather than avoided.
