Reddit mentions of SF Cable, 3 Prong Plug Adapter, USA NEMA 5-15R to IEC 60320-C14

I guess for the right person this might be useful? Maybe? Isn't an extension cord way more common than that type of cord end?

As far as actual electrical issues go, the box needs to have a ground wire attached, there should be a fuse or something to ensure you're not overloading the cord that goes in the bottom, and the box isn't meant to be cut into like that.

Why not just buy this.

I fabricated some of these and they're the most amazing things:

• an IEC C14 to C6 adapter
  
• an IEC C14 to NEMA 5-15 adapter
  
• A C6 to C14 adapter
  
• C6 to NEMA 5-15 adapter
  
• The last-case adapter: Stubby C16 to NEMA 5-15 -- A few of these transmogrify anything.
  
  
  These adapters have gotten me out of some of the most insane situations. "Hey so I have a laptop but the plug doesn't work" "do you care about the LCD?" "not really" FANTASTIC! here's a cable to fix your problem.
  
  

Ah, this type of thing looks familiar. VGA + PS/2 KVM switches spread round with tons of power strips and adapters, plus ethernet cables everywhere, used for multiple computers, probably repair.

Use those power bars, remove all of the other strips and just use Universal power cords with adapters like these, this, and that on the ends for various purposes. It basically becomes your own customizable, variable power squid

Might take velcro and bundle some of those together if necessary too.
We figured that out recently for our shop for similar usage and it have been a lifesaving revelation.

And if you need some special type of adapters, here's the listings from Wikipedia common cord ends.

You will then need a power supply that provides the correct current capacity. If you use the whole 15m of ribbon, that is 12A for that ribbon.

Also, that's a really long run for LED ribbon. You will see voltage drop, especially in this cheap stuff. You can combat this by running power to both ends of the ribbon. You could also cut it into several smaller strips, but you will need a controller for each section.
