Example: You want to run a cable for a powerpoint in your shed 100m away. You may only pull 10A from a power point so that becomes the full load current. Lets say the biggest power tool you are going to run has a 1200W motor; divide that by 230(volts) gives you its full load requirement at 5.2A. Start up current for a motor is five times the

Electrical formulas play a great role in finding the parameter value in any electrical circuits. Most commonly used electrical formulas are formulas related to voltage, current, power, resistance etc. Volt is a unit of electrical potential or motive force – potential is required to send one ampere of current through one ohm of resistance.

Ensure the cable can take the fault level – for most larger cables this tends not to be a problem, but for smaller cables, it can be an issue. Use myCableEnginering to carry out the calculations – it makes life easier. Be practical – make sure your cable size is reasonable.
