Can I ask what the difference is between 14gauge wire and 14awg wire is? Are they both not the same? Sorry for the dumb question but I'm new and not trying to screw things up.Is either one of these suitable for power injection?
Majority of my power injection is 14AWG or 18AWG. There is a handy calculator to determine what size wire is needed. https://www.da-share.com/calculators/cable-voltage-drop/ Majority of pigtails,extensions and wire on pixel strings is 18AWG or smaller which generally limits you to 7.5 amps. 18AWG should take care of majority of power injection if the power supply is close to the pixels.
