PE supply system connection according to EN 61800-5-1

Leakage currents ≥ 3.5 mA can occur during normal operation. Observe the following for reliable PE connection:

• Supply system lead < 10 mm²:
• Route a second PE conductor with the same cross section as the supply system lead in parallel to the protective earth via separate terminals, or
• Use a copper protective earth conductor with a cross section of 10 mm²
• Supply system cable 10 – 16 mm²:
• Use a copper protective earth conductor with the cross section of the supply system lead.
• Supply system cable 16 – 35 mm²:
• Use a copper protective earth conductor with a cross section of 16 mm²
• Supply system lead > 35 mm²:
• Use a copper protective earth conductor with half the cross section of the supply system cable.
