Hello students, let us consider the different race ways to determine maximum ampacity of copper conductors given that 6, 12, tw, 75.
00:15
It means that 6 indicates 6 copper conductors of size 12 american wire gauge, tw means thermoplastic insulated wire and this 75 is temperature that is 75 degree celsius and for this notation we have maximum ampacity range will be 30 ampere.
00:52
Now consider next 25, 14, tw, 60.
01:02
Here 25 copper conductors size 14 american wire gauge, tw is thermoplastic insulated wire and 60 degree celsius.
01:16
For this notation we have 20 ampere.
01:21
Next given 13, ash, 6, t, 90, nylon...
