What is derating factor of battery?
batteries derating factor will change ,depends upon the temperature& cable size which arelinked with batteries bank.
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.
What is derating factor in case of diesel engines?
air flow speed
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
The calculation used to determine amperage of a conductor based on the total number of conductors in a conduit is called A derating B voltage drop C conduit fill D conductor fill?
derating
Definition of derating?
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.
Can you run a 12 amp heater on 125 feet of 12-3 wire?
depending on the insulation type. Most 12 AWG wire will carry that current capacity either. Unless you are running it in the desert or some place extremely hot where derating becomes a factor.
What is the root for benefactor?
Bene, meaning well, and factor, meaning maker or doer.
What is the proper factor of 42?
the meaning of life
What is the difference between a safety factor and a factor of safety?
Both are meaning the same definition. simply you put factor beyond the safety.
What is meaning of factoring?
of Factor, The act of resolving into factors.
