Keep an eye on those 13amp plug fuses

Hang up your Chisels and Plane blades and take a load off with a recently turned goblet of your favourite poison, in the lounge of our Gentlemen's (and ladies) Club.

Keep an eye on those 13amp plug fuses

Went down into the kitchen and assailed by hot electric smell. While seeking the source of the smell, there was a very loud bang and the kitchen ring main breaker tripped. I could see a very black socket and this plug.

Yes, that is daylight all the way through.

I'm guessing that the fuseholder got slack and caused a high resistance and due to the load (tumble dryer) gradually heated up the plug and the fuse blew. Although quite why the fuse blew I have no idea. But with enough vigour to blast out both sides of the plug.

The socket is being replaced as well.

Wow that’s worrying - glad it wasn’t worse.

I read something written by a Fire Brigade Chief not to leave tumble-dryers etc unattended!
We often used to run our dishwasher over night.

I have never seen anything like that before. Very sobering.
Glad I don't have a tumble dryer. Although WM and DW used regularly on our cheaper overnight tariff.
I do not think therefore I do not am.

I was reading about something similar with a moulded on plug.

That hole is where the connection between the fuse and the cable would connect. Must have been a poor crimp that failed over time.

Obviously you can't check a moulded plug but the ones to check regularly are the rubber duraplugs. The sulphur in the rubber cause the silver plating on the fuse to go black with silver sulphide and that can cause trouble. It rubs off easily enough.
