Where: \(I_c\) = cable current rating (A) \(I_{load}\) = load current (A) \(K\) = derating factor Earthing and bonding calculations are used to determine the earthing and bonding requirements for an electrical system.
\[V_d = rac{2 imes L imes I imes R}{1000}\] electrical design calculations needed for projects pdf
\[P_{total} = P_1 + P_2 + ... + P_n\]
