Voltage Drop Calculator - Voltimum UK
Jul 1, 2022 · Voltage Drop Formula. The voltage drop formula is expressed as Voltage Drop = ( mV/A/m ) x L x Ib / 1000. mV = millivolts. A = Amps. L = Cable Length in meters. Ib = Design Current in Amps. / = Divide by 1000 to convert the result from Millivolts to Volts. mV/A/m = millvolts per Amp per Meter. To find the mV/A/m for a type of cable, the volt ...

Conduit sizing - Voltimum UK
Aug 18, 2022 · Answer 3. Using the formula to determine the minimum internal diameter of the conduit: Taking the nominal wall thickness of the conduit as 1.6 mm would give a minimum internal diameter of 19.1 + (1.6 x 2) = 22.3 mm. Therefore, the minimum standard size of conduit that complies with the 35 % space factor is 25 mm.
