I have a standard electrical outlet supplied by a 20 amp breaker, outputting

118 volts. For something being planned, that circuit is needed to output 125 volts at 20 amps capability. Is there a good method for this, and what is the most economical, feasable, and most practical method? It needs to be fairly close to the 125 volt figure, as much as practical. Obviously, a step-up transformer might be the solution, but what about the ability to find one to output the 125 volts? Is there a practical homebrew buck and boost method? I've done a decent amount of industrial, automotive, house wiring and troubleshooting, but I'm a relative newby at this type of theory, so be gentle.Thanks, RJ
