4.1.5 Cross-sectional areas
The cross-sectional areas of the mains power lines (L, N, and PE) and, if required, the
safety loop (safety limit thermostat, water shortage, etc.) must be sized for rated
currents according to the selected external primary fuse. The cross-sectional areas of
the other cables must be sized in accordance with the internal unit fuse (max. 6.3 AT).
Min. cross-sectional area
0.75 mm²
(single- or multi-core as per VDE 0100)
Cable insulation must meet the relevant temperature requirements and environmental
conditions.
