Anyone made the "Bob Crump" home-made powercord?

Anyone try the 90 degree IEC (Shurter or P&S?), or 90 degree P&S male AC plug in this (or similar) design?
Also, can these connectors accept 10AWG? Can a P&S 5242, or only the 20 amp 53XX?
Thanks, folks...I ask because I want to make up PCs from the 10-2 Romex I'm using for dedicated lines, so as to power my remote monos. IOW they're hidden, so I may as well go for 10AWG instead of aesthetics.
Thanks for the advice. Ernie

Thanks, Kevin. Decided to use 10-3 for the monos line, but Belden 83803 12-3 FEP over tinned copper for front end dedicated lines AND PCs. Hope I can get it into the Schurters.... Ernie
