Table 32. International Cable and Fuse Sizes—380 Vac to 440 Vac Ratings
Notes
1
Line and motor cable size is selected according to IEC60364–5–52:2009 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 IEC60364–5–52:2009 for suitable cable sizes.
2
Earthing conductor size is determined by the cross–sectional area of phase conductors according to IEC/EN61800–5–1:2007 Table 5. So if phase conductor size
is changed, earthing conductor size should also be changed accordingly.
3
If power cubes or bypass are used, a Class gG/gL fuse is recommended.
