## What is Motor Cable Sizer?

Motor Cable Sizer brings you premium voltage drop and short circuit calculations. 

You can choose between a simplified calculation with only MCC and motor or a detailed calculation with transformer and/or switchboard added to the single line diagram. Extensive parameters can be customised and configured to match your specific network.

With Motor Cable Sizer, you have voltage drop calculations for any motor or distribution board at your fingertips, anytime, anywhere. You can choose your protection types (fuse / circuit breaker) and investigate trip times for different scenarios based on the selected configuration:

Switchboard:
* 3-phase short circuit
* Phase to phase short circuit
* Phase to PE short circuit

MCC:
* 3-phase short circuit
* Phase to phase short circuit
* Phase to PE short circuit

Motor:
* Advanced motor parameter estimation based on nameplate data
* Nominal load
* Start up
* 3-phase short circuit
* Phase to phase short circuit
* Phase to PE short circuit

Trip times can be further studied in accurate time-current charts.

A full detailed pdf report with your settings and calculated values can be created with one simple tap.
