[QUOTE="SPECIAL LOCATION, post: 29939, member: 250"] Just to add... This is the reason why a Main isolator switch for a CU is spring assisted in its action when switching OFF.. So it pulls the contacts open quicker.. Thus reducing arcing & sparking which increases the life span of the main switch contacts.... and stops em welding together when breaking under FULL load!!
