There are two main considerations for sizing DC wiring from the output of a power supply to its load. They are ampacity (fancy term for the number of Amps) and voltage-drop (remember ohms law: V = I x ...
My first job in the trades was as an electrician’s apprentice doing tasks, such as pulling wire, building light fixtures, and moving scaffolding in grocery store renovations. I moved into HVACR and ...
Many DIY enthusiasts have to contend with electrical wiring eventually in some capacity. The descent into this rabbit hole often begins with the fundamental question: What exactly is a wire gauge, and ...
Figure 1: Fabrication and ampacity of CNT–Cu composite. We numerically estimated the ampacity of the CNT–Cu composite by assuming that the material ruptured by current-induced Joule heating, leading ...
