electrical switchboard box combination of equipment within the switchgear enclosure allows them to interrupt fault currents of thousands of amps. Gas (SF6) circuit breakers sometimes stretch the arc using a magnetic field, and then rely upon the dielectric strength of the SF6 gas to quench the stretched arc. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air ...
