Here you have the option of calculating the required cross-section of copper connection cables
in the DC network. Normal
DC consumers, such as DC motors, are connected here.
Attention:
The cable calculator offered here is only a rough tool for estimating
the cross-section.
A = (2 x I x L) / (K x Δu x U)
Here is an example:
A 24 V DC motor has a rated current of 2.47 amps, a cable length of 28 m,
the voltage drop of the cable is 2%.
What cable cross-section results from these specifications?
A=(2 x I x L) / (K x Δu x U)
A=(2 x 2.47 A x 28 m) / (56 x 0.02 x 24 V)
A=(138.32) / (26.88)
A=5.15 mm²
The next largest suitable cross-section is 6 mm²!
Units of measurement:
Cross-section A=mm²
Voltage u=Volt [V]
Current i=Ampere [A]
Kappa copperK=56 [m / Ω x mm²]
Delta U Δu = %
