Additional requirements placed on the protective conductor ① according to IEC60204-1:
• For permanent connection, the protective conductor must fulll at least one of the following
conditions:
– The protective conductor is routed so that it is protected against damage along its
complete length.
Cables routed inside electrical cabinets or enclosed machine housings are considered to
be adequately protected against mechanical damage.
– As a conductor of a multi-conductor cable, the protective conductor has a cross-section ≥
2.5mm² Cu.
– For an individual conductor, the protective conductor has a cross-section ≥ 10mm² Cu.
– The protective conductor consists of 2 individual conductors with the same cross-section.
• When connecting a multi-conductor cable using an industrial plug connector according to
EN60309, the protective conductor must have a cross-section of ≥2.5mm²Cu.
• Observe the local regulations for protective conductors subject to a high leakage current at
the operating location.
