In Australia, for example, the earth pin on a 15A plug is taller than a 10. This lets you plug 10A rated extensions and appliances into a 15A capable socket, but not vice versa.

Amperages above that have dedicated plugs, and any available adaptors only go downwards in amperage limit, not upwards.

This of course doesn’t stop people getting creative with a screwdriver, or from creating immense chains of small gauge extensions, but it certainly goes a long way to reducing risk.

I’ve never heard of being able to plug a 15A into a 10A socket. Everywhere I’ve seen them, they are keyed to physically prevent this. What country are you in?

How does RF attenuation affect power safety?

Your 2nd best bet would be to get the pin spacing, and filter your search using that.

Your first best bet would be to just replace both ends.

I settled on a ‘standard’ and just bought a massive kit of each of those connector types- wire-wire, wire-board, wire-panel in M and F, in various pole counts. Buy once, cry once.
