Power cable sizes and fuses
Cable dimensioning for rated currents (I
the corresponding fuse types for short-circuit protection of the input power cable.
The rated fuse currents given in the table are the maximum for the mentioned
fuse types. If smaller fuse ratings are used, check that the fuse rms current rating is
larger than the rated I
power is needed, multiply current I
Check that the operating time of the fuse is below 0.5 seconds. The operating
time depends on the fuse type, the supply network impedance as well as the cross-
sectional area, material and length of the supply cable. In case the 0.5 seconds
operating time is exceeded with the gG or T fuses, ultra rapid (aR) fuses will in most
cases reduce the operating time to an acceptable level.
Cable temperature ratings and sizes
Use power cables with a temperature rating of at least 70°C (158°F) maximum
permissable temperature of the conductor in continuous use. However, if you use
cables smaller than shown in the table below, use cables with a temperature rating
of 90°C (194°F).
Additional US requirements
If metallic conduit is not used, type MC continuous corrugated aluminium armor
cable with symmetrical grounds or shielded power cable is recommended. The
power cables must be rated for 75°C (167°F).
