M\u00e4rkta anslutningar.<\/p>\n

Elektriskt \u00f6versp\u00e4nningsskydd fungerar genom att avleda den extra energin i den elektriska \u00f6versp\u00e4nningen bort fr\u00e5n huvudkretsen, vanligtvis till \u201cjorden\u201d.<\/p>\n

\u00d6versp\u00e4nningsskyddsanordningar (SPD) som \u00e4r anslutna till huvudf\u00f6rdelningscentralen \u00f6vervakar st\u00e4ndigt matningssp\u00e4nningen.<\/p>\n
