I did testing with a double-run of 14awg romex (that's 2x14awg which makes an 11awg totalPlease describe the 'test' in detail from start to finish
Unless you were able to compare the original to the new, in real time, any perceived change is pure fantasy
voltage in the tiny 14awg wire being restricted by the high dielectric constant on the insulationROTFLMFAO!!!
Gimme a break!
