How many kW can a 16mm cable carry?
Dave. “Using the TLC volt-drop calculator, it gives a max of 21Kw for 17metres of 16.0mm XLPE SWA Hope this helps, Dave.” 21 kW divided by 230 V gives ~91.3 A which exceeds the rating of 89 A given for Method C in table 4D4A….
How do you calculate the current carrying capacity of copper cable PDF?
Copper current-carrying is equal to 1.2 times the total volume of the copper (lenth*breath*thickness). Lets us have a simple example of 35 sqmm bus bar. Apply our equation, Current carry capacity of 35sqmm bar = 1.2* 35 = 42 Amps.
What size breaker do I need for 16mm cable?
The 16mm cable should be protected at the origin by a 63amp RCD unit. At the distribution board at the other end each lighting circuit should be protected with a 6 or 10 amp circuit breaker and the power circuits (if wired as a ‘ring circuit’) should be protected with a 32amp circuit breaker.
Is 10mm earth OK with 16mm tails?
You pick the tails cable size in relation to the main fuse, i.e 100a main fuse is 25mm2 tails and should be 16mm2 earth or 60-80a is 16mm2 and 10mm2 earth….See Also:

How do you calculate copper cable size?
Cable Sizing Calculator 230V and 415V Voltage Drop. To calculate the Cable Sizing one needs to divide the voltage running through the cable by the target current. For instance, If your wire has a voltage current of 150 Volts and your target is 30 then you divide 150/30.
How do I calculate copper wire size?
FAQ
- Multiply the resistivity (Ω•m) of the conductor material by the peak motor current (A), the number 1.25, and the total length of the cable (m).
- Divide the result by the voltage drop from the power source to the motor.
- Multiply by 1,000,000 to get the result in mm2.
Can I run a 10.8 kW shower on 10mm cable?
You are right on the border with 10mm unless you can meet the clipped direct requirements. It is 45 amp at 240 volts and a touch under 47 amps at 230 volts.
What is 16mm wire used for?
16mm Armoured Cable is a power and auxiliary control cable, designed for use in mains supply electricity. Used for underground systems, cable networks, power networks, outdoor and indoor applications, and cable ducting.
