conductor current rating

Best answer


The currentrating of bare conductors is affected by the conductor temperature,weather parameters,heat losses due to convection and radiation,the solar heat gain and conductor resistance,the calculation of which is governed by a steady-state and a non-steady-state heat balance equation.

  • What is the current rating of a copper wire?

  • Current Load Ratings – Copper (amps)1) . . 1) Current ratings for up to 1000 V, PVC-insulated single and multicore wiring cables, ambient temperature up to 30oC Values for resistance are based on electrical resistivity for copper 1.724 x 10-8 惟 m (0.0174 渭惟 m) and electrical resistivity for aluminum 2.65 x 10-8 惟 m (0.0265 渭惟 m).

  • What are the factors affecting the current load of a conductor?

  • Be aware that the current load depends on installation method – the enclosure – and how well the resistance heat is removed from the cable. Operating temperature of the conductor, ambient temperature and type of conductor insulation is important.

  • What limits the amount of current passed through a wire?

  • There are many factors which will limit the amount of current that can be passed through a wire. The larger the circular mil area, the greater the current capacity. The amount of heat generated should never exceed the maximum temperature rating of the insulation.
