Figure 13: AC Mains Cable
The Earth Ground wire should be slightly longer than the two other wires so if the cable is
accidentally pulled the line and neutral wires are disconnected first.
You need to connect the AC mains. Use only cable with 3 wires in a size of 1.5 to 2.5 mm² (AWG 14 to
16).
An external 6 to 16 A line fuse (type B) or an equivalent circuit breaker is required for
the AC mains installation.
