Cable maximum current carrying capacity
WebThe Maths behind SWA cable volt drop. The following formula is used to calculate Voltage Drop = (mV/A/m) x Ib x L / 1000. (mV/A/m): To find the value for (mV/A/m) we need to look in the current carry capacity and voltage drop tables on the pages below. Ib: This is in AMPs, design current which is watts divided by voltage. WebApr 10, 2024 · To determine the appropriate wire size for your system, calculate the maximum current that will flow through the wire. Do this by adding the max current of all the panels in your system and multiply that by a safety factor of 1.25. This will give you the current-carrying capacity of the wire you need.
