This is BULL CRAP, it says NO SUCH THING do NOT listen to amatures about electrical; unless you like getting people killed.
#12 copper is rated for 20 amps Max. Period. no exceptions. Many amatures assume that because the NEC chart 310.16 states 25 amps under the insulation rated THHN that is the amperage answer, but that is NOT the rating for Fuse (breaker, same thing) protection. That chart is a starting point of the calculations of voltage drop. #10 is rated for 30 amps. the fuses/breakers are for protecting the wire from over heating and causing a fire. It state this in the fine print at the bottom of the page.
I have had too many jobs replacing burnt wiring from people guessing they can do it them selves. If you have to ask then Hire a professional.
Also beleive it or not, If you jury rig your own stuff, and there IS a fire because of it, not only can you be sued by any one injured, but the Insurance company MAY refuse to pay for "not to code wiring practice". That is why contractor's carry Liability Insurance, because property insurance by the owner does not cover mistakes by installers.
Do what you want to, But I get mad when I see people pretendung to know electrical codes. even tho they may mean well.
and I think QuenchCrask meant a double 50 amp breaker NOT 2 25 amps breakers. I amso know typos when I see them, as I make many of those.
