The following cable cross-sections can be used for the connection of single cables:
Cable cross-section
AWG (American Wire Gauge) 20-14 (0.5 mm
2
to
2.5 mm
2
(0.0008 in
2
to 0.0039 in
2
)) solid
or bare stranded wire with or without UL listed boot-
lace ferrule
Use AWG 14 (2,5 mm
2
(0.0039 in
2
)) for currents from
5 A to 10 A.
Use copper conductors only, at least certified for a
temperature of +105 °C (221 °F).
Bootlace ferrule with plastic shroud L = 12 mm (0.47 in)
Stripped length (for use without bootlace ferrule) 12 mm (0.47 in), only copper lines may be used.
Single cables and bridges can be connected together for horizontally arranged clamping points. Note that
adjacent bridges are installed reciprocally.
