I thought, too - a bottle opener. But what about the one bottom left? Is it a piece of soft cheese wrapped in tinfoil?

Whatever - but that picture would make more sense if the ratings were divided by 10

Maybe if the cheese had been refrigerated it would be a way to quickly soften it to room temperature!

That's a wedge of Laughing Cow soft cheese!

The numbers are representative of common fuse ratings in the US I believe. Then again the last time Isaw actual fuses in a house or building was probably the '70s.

US voltage is 110V - EU 220V - that means the current for same power is 2xEU-current.
120 vs 240 - 0r 115 vs 230 - same difference.

Our most common household fuses are 10A and 16A - my house runs on 3-phase system - like any other place here - and the main fuses are 3x35A

16A x 220V provides 3,5kW power - that is enough for running a heater for a fairly large room - if insulation is appropriate.

Fuses in range 100A and up are common in heavy industry - never at any household.

Therefore my suggestion of scaling the picture by 10 - after all this writing I'm ready to reduce it to 1/100 - more realistic.

The left bottom item is a famous French “la vache qui rit” cheese piece. We buy those boxes always on our holidays in France… however, never used them as fuse… should have thought about that earlier….🤔

My house originals are like those. Whenever I do some upgrades - I use the new resettables.

I don't know what I was thinking saying those fuses were household values. Holy crap - most houses here in the US don't have more than 200A service!

dread, FYI:

The last mostly-copper cents (95% copper metal composition) were produced by the Denver Mint on October 22, 1982.
