$523$ Current$-$carrying capacities

$523\mathrm{.}1$ The current to be carried by any conductor for sustained periods during normal

operation shall be such that the temperature limit of the insulation is not exceeded. This

requirement is fulfilled by application of Table $52\mathrm{.}1,$ for the types of insulation given in this

table. The value of current shall be selected in accordance with $523\mathrm{.}2$ or determined in

accordance with $523\mathrm{.}3.$

Table $52\mathrm{.}1-$ Maximum operating temperatures for types of insulation

$523\mathrm{.}2$ The requirement of $523\mathrm{.}1$ is considered to be satisfied if the current for insulated

conductors and cables without armour does not exceed the appropriate values selected from

the tables in Annex B with reference to Table A$\mathrm{.}52\mathrm{.}3,$ subject to any necessary correction

factors given in Annex B$.$ The current$-$carrying capacities given in Annex B are provided for

guidance.

NOTE $1$ It is recognized that National Committees may wish to adapt the tables of Annex B to a simplified form for

their national rules. An example of one acceptable method of simplification is given in Annex C$.$

NOTE $2$ It is recognized that there will be some tolerance in the current$-$carrying capacities depending on the

environmental conditions and the precise construction of the cables.

$523\mathrm{.}3$ The appropriate values of current$-$carrying capacity may also be determined as

described in the IEC $60287$ series, or by test, or by calculation using a recognized method,

provided that the method is stated. Where appropriate, account shall be taken of the

characteristics of the load and, for buried cables, the effective thermal resistance of the soil.
