Notes:
-
Line and motor cable size is selected according to IEC 60364-5-52:2009 Table B.52.4 for copper conductor
with PVC insulation with a wiring condition of ambient temperature 30 °C in air and an installation method of
“B2” (cables in conduit and cable trunking systems). For other wiring conditions, please refer to the standard
of IEC 60364-5-52:2009 for suitable cable sizes.
-
Earthing conductor size is determined by the cross-sectional area of phase conductors according to
IEC/EN 61800-5-1:2007 Table 5. So, if phase conductor size is changed, earthing conductor size should
also be changed accordingly.
-
If power cubes or bypass are used, a Class gG/gL fuse is recommended.
