AI Thread Summary
The discussion highlights the evolution of the penny, noting its transition from a solid copper alloy to a bimetallic composition. This change is seen as a significant point of interest. Additionally, there is a mention of the 2000A slow-blow fuse, specifically designed for European 240V circuits, which requires an 11mm combination wrench. For US circuits, a 3/8" combination wrench is recommended, with a 3/8" - 7/16" wrench being a suitable alternative in emergencies.

I suppose the penny was dropped when it went from a solid copper alloy to bimetallic.

I was wondering why the penny wasn't included...

The 2000A slow-blow fuse (an 11mm combination wrench) is for use in Europe with their 240V circuits. For the US, use a 3/8" combination wrench. In a pinch, a 3/8" - 7/16" wrench will suffice.
