1 sq..mm have max. capacity is 10 ampere if these are of copper approximately than 120 sq..mm having current carrying capacity is 1200 ampere
Its Depend what kind of load you are using and normally 120mm copper can take up to 300 upto 350 continues
30 amps
It depends on the type of conductor, how many cores, type of insulation, how it is installed, etc. You will need to consider each of these factors, and check it out in the appropriate conductor data tables (e.g. in BS 761:2008).
in air it will be 665Amps.
25 amps, 6000 watts
the current carrying capacity of 16sq.mm copper conductor is as below: For Single phase A.C or D.C is - 76 amperes (VIR insulated) and that For Three phase A.C or D.C is - 66 amperes. (rubber insulated)
30 amps
What is current carrying capacity of 50x8 mm copper flatbusbar.
12 swg current carrying capacity
It depends on the type of conductor, how many cores, type of insulation, how it is installed, etc. You will need to consider each of these factors, and check it out in the appropriate conductor data tables (e.g. in BS 761:2008).
170A
You have to be specific. whether the conductor is aluminum or copper. Current carrying capacity will be different for these two types. Copper cable can take more load than aluminum cable for same diameter.
570amps on 3phase 415volts
in air it will be 665Amps.
It can carry upto 100 Ampere.
25 amps, 6000 watts
300ams
You don't calculate the current-carrying capacity, you find out from the appropriate Tables in your country's wiring regulations. In the UK, this is BS 7671:2008 Requirements for Electrical Installation.The reason you must do this is that the current-carrying capacity of a cable depends on the conductor type, number of cores, the type of insulation, the method of installation, etc. Allthese factors are taken into account in these Tables.For a 2.5-mm2 copper cable, the current-carrying capacity can vary from around 22 A to around 36 A, depending on the factors described above.
