Please explain the b and c type breaker. I am an electrician and have never heard of such.
Type B devices are generally suitable for domestic applications. They may also be used in light commercial applications where switching surges are low or non-existent.
Type C devices are the normal choice for commercial and industrial applications where fluorescent lighting, motors etc. are in use.
Type D devices have more limited applications, normally in industrial use where high inrush currents may be expected. Examples include large battery charging systems, winding motors, transformers, X-ray machines and some types of discharge lighting.
