Spark gap for earth bonding with brass clamps for ø 8 – 10 mm (50 – 70 mm²) cable and 30 x 2 – 30 x 3.5 mm tape.
AT-050K is the most appropriate means of joining the different earth connections when this
connection cannot be made directly as, for example, it may cause corrosion problems.
When a discharge occurs and the voltage increases in the earth connections, the spark gap
will activate, directly joining the earth connections and thus preventing current passing from
one to another through equipment or internal installations.
