S-BT-ER, S-BT-EF
Single point connection
Functional bonding and terminal connection in a circuit
Examples
Applications
Functional and protective bonding of pipes *)
(outer diameter of installed surface
≥
150 mm)
*) only for Type A cable connections
For permanent current (leakage current) due to static charge built up in pipes or when closing
an electrical circuit.
Type A
Protective bonding circuit – Double 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 permanent current Ith = 57 A)
35 mm² (2 AWG) copper (tested permanent current Ith = 125 A)
120 mm² (4/0 AWG) copper (tested permanent current Ith = 269 A)
• Fastening of thicker cable is acceptable, if the maximum allowable permanent current Ith
is not exceeded and the provisions on cable lug thickness tcl are observed.
