Current rate
PVC-insulated
single and multi conductor wiring cables according to UL-AWM and CSA-TEW
standards are used in switchboard
and distribution cabinets of electrical equipment and as well as for the
installation of machines and transformers in protecting
tubes.PVC-insulation is allowed at maximum temperature range of 105°C.The
indicated values stated in the following tables are
considered as guiding values. In critical situation the rules and
recommendations for the current ratings should be followed.
For single
conductor cables at ambient temperature up to 30°C
