It determines ·for B2 installation method· the minimum section of the cable
through which the maximum current allowed in continuous duty can
circulate on three-phase wires in PVC hoses or installed on the machine
through conduits or channels according to UNE-EN 60204-1:2007.
The ambient temperature is assumed to be 40°C/104°F.
MANDATORY. The dielectric insulation of the cable must be enough to
withstand the test voltage at a minimum of 2 000 V AC for 5 minutes for
cables supporting voltages over 50 V AC (alternating current) or 120 V DC
(direct current). Refer to the recommendations of the cable manufacturer
before doing the installation.

INFORMATION. If installation methods other than B2 are available and/or
demands are lower than the maximum provided by the power supply, see
appendix D.1.2 of UNE-EN 60204-1:2007 to determine the corresponding
method and depending on the rated current requested for the power supply,
obtain the minimum required cable section shown in table 6 of this
regulation. Note that the section obtained can be less than that given in table
T. H7/3 .
