Sounds like a defect i the socket, or possibly a wire is touching something
within the outlet box. Or insullation worn through.

I'd call an electrician in the morning to come and check it out. Might be a
wall fire in the making.

Fortunately, it is tripping the breaker instead of heating up.

hi there,

i have an old PC that after I use I have a habit of unplugging from
the wall. The last few times though when i unplug the turned off PC a
Circuit breaker is tripping. why could removal of a plug of a switched
off device cause this?
