Medium Voltage Cable Ampacity

For example 3 0 awg copper has an ampacity of 200 amps at 75 while 3 0 awg aluminum has an ampacity of 155 amps at 75.

Medium voltage cable ampacity. 15kv trxlpe concentric neutral. Step 3 a load in step 1 is 100a or less or conductors are sized 14 awg through 1 awg select conductor that can handle the load from 60 c column. Home products medium voltage primary underground distribution. Step 1 determine the load on the cable using article 220 part ii of the national electrical codestep 2 turn to table 310 15 b 16 of the national electrical code scroll above or below to see ampacity chart.

If you continue without changing these settings you consent to this. Table 310 15 b 16 formerly table 310 16 allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient temperature of 30 c 86 f. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Each has a different ampacity for a specified gauge size and these ampacities are found in nec table 310 15 b 16 for the calculations in this app.

Ampacity copper and aluminum type mv 90 and mv 105 cables author. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. Medium voltage primary underground distribution.
