For discharging short circuit current while protecting electrical equipment or earth / ground
cable trays and ladders.
Protective bonding circuit
Double point connection
Single point connection
Note:
• Recommended maximal cross section of connected cable
according
IEC 60947-7-2 and IEC 60947-7-1:
10 mm² (8 AWG) copper (tested short circuit current I
cw
= 1.20 kA for 1 s)
35 mm² (2 AWG) copper (tested short circuit current I
cw
= 4.20 kA for 1 s)
120 mm² (4/0 AWG) copper (tested short circuit current I
cw
= 14.40 kA for 1 s)
according
UL 467
:
10 AWG copper (tested short circuit current I
cw
= 0.75 kA for 4 s)
2 AWG copper (tested short circuit current I
cw
= 3.90 kA for 6 s)
4/0 AWG copper (tested short circuit current I
cw
= 10.10 kA for 9 s)
• Fastening of thicker cable is acceptable, if the maximum short circuit current
I
cw
and the exposure time is not exceeded and the provisions on cable lug thickness
