CIRCUIT BREAKER TYPES - How they work and inrush currents

This is an introduction to the selection of MCB types and how a knowledge of inrush currents at start up can influence the choice of device. We look at thermal sensing of overload currents and electro-magnetic responses to short circuit and fault currents. Should a type B or type C be installed, and what are the implications on safety and circuit performance. And we also look at the different kinds of devices, single pole, three pole, four pole etc. This video is a good overview of the subject.
