Default Re: Failing Schaffner IEC Inlet Filters

It's likely the burn was a result of a spray of vapourised copper. Very common when conductors and fuses do a rapid vanishing act. It certainly sonds like a very large fault current even if for a short time. Fuses and breakers all have current versus time curves and the short-time currents ar very large.

Glad he's fixable
