I didn’t think about matching pitch in that way, but it could come in handy.
By the way does anybody know offhand what the pitch of those dual-in-line Eurorack connectors is? The terminal blocks I ordered have a pitch of 5mm, which isn’t compatible with veroboard or breadboards. There are workarounds but I’ll have to muck about a bit to find one that works best for my needs.
The IDC connectors are 0.1 inch pitch, or 2.54 mm (half that on the cable side). Random datasheet drawing:
As for the terminal blocks, 5 mm is close enough to 5.12 mm 5.08 mm that it’s usually not a problem fitting these on a stripboard; worst case you may have to make the outer holes a bit larger.
0.2" = 5.08 mm. And my guess is “5 mm pitch” is really 5.08 mm, but as @fredrik says, it’s close enough not to matter anyway.
0.2" = 5.08 mm
Oops. Guess my brain decided that 256 is a less weird number than 254 
But 5 mm pitch is definitely a thing; the AK300 footprint you used above is slightly narrower than the 2.54 IDC pitch (it’s made by a German company, after all).
Bloody Imperial again.
So I guess wrong sometimes
(but that German company does make Imperial spacing ones too)
Thinking of just repurposing UK domestic three core mains cable for internal power wiring. I’ll have to make sure the screw terminals will take the wire gauge.
