NOTE When lightning equipotential bonding is established to conducting parts of the structure, part of the lightning current
may flow into the structure and this effect should be taken into account.
The minimum values of the cross-section of the bonding conductors connecting different bonding bars
and of the conductors connecting the bars to the earth-termination system are listed in Table 1.
The minimum values of the cross-section of the bonding conductors connecting internal metal
installations to the bonding bars are listed in Table 2.

or connecting bonding bars to the earth-termination system
