Abstract

Conductive elements (104A-C) are positioned within a housing (100) of an electric device. The conductive elements (104A-C) are arranged such that in an event of an electric arc (106) occurring between the conductive elements (104A-C) an electromagnetic force is exerted upon plasma of the electric arc (106) such that the electric arc (106) is directed towards a wall (108) of the housing (100). Furthermore, a conductor configuration (102) includes conductors (104A, 104B, 104C) and sacrificial electrodes (118A-C) positioned within a housing (100) of an electric device, wherein the conductors (104A-C) are arranged such that in an event of an electric arc (106) occurring between the conductors (104A-C) an electromagnetic force is exerted upon plasma of the electric arc (105) such that the electric arc (106) is directed towards the sacrificial electrodes (118A-C).
