The verb derating means to assess the value of (some types of property, such as agricultural land) at a lower rate than others for local taxation; operation of a machine at less than its rated maximum power in order to prolong its life.

What is current value after derating factor considered?

Once derating factor is considered the size of cable for perticular electrical load increased by the multipling factor.i,e if 2.5MM2 cable is capable to carry 14amp. of current in general then with 40% of derating fator it can carry only 8.4amp.

How many current carrying conductors are allowed in a raceway before derating?

You can put three ccc's in a conduit (any size conduit) before you derate. Keep in mind that for single phase loads (lighting, receptacles) the neutral is also counted as a current carrying conductor. This derating factor does not apply to nipples 24 inches long or less. See NEC Table 310.15(B)(2)(a) for full details on derating regarding ccc's.

What is the derating?

Derating factor depends on ambient temperature & how u r laying the cable ie., in Air,Duct,Burried. normally the current carring capacity of a perticular cable is calculated at 40*c, but if u lay the cable in air then it includes the temparture around it,if it increases more the 40*c then the conductor gets heated up by increasing the resistance in it thus the current carring capacity of a given cable decreases, so we will derate the cable The derating factor of induction motor is the ratio of the calculated output power to the rated power
