Type earth electrodes are vertical
or horizontal earthers (earth rods). Type earth elec-
trodes are any surface earther (ring earthers, founda-
tion earthers).
Cross-connector
Corrosion protection strip
Round conductor
Connection clips
Earth rods (observe corrosion protection for connectors)
Type earth rods with ring equipotential bonding

Type A
• Horizontal earth electrodes
• Vertical earth electrodes (earth rods)
Type B
• Ring earth electrodes (surface earthers)
• Foundation earth electrodes
External and internal lightning protection systems
2.3 Planning methods
IEC 62305-3 demands continuous lightning protection
equipotential bonding. This means individual earthing
systems must connected together create glob-
al earthing system
