The graph (left) illustrates the conductor temperature rise of a single insulated wire in ‘Free Air’.

Table A (Below)
Conductor size, resistance and current carrying capacity.

Table B (Below)
Multiplying factor for multicore cables of the same size. Example for 22 AWG twisted pair 7.4 amps (single) x 0.825 = 6.1 amps
