In this episode of “EC&M Tech Talk,” Randy Barnett, a journeyman electrician, electrical instructor, inspector, author, trainer, and electrical safety expert discusses the ampacity level of conductors ...

One of the standard things home inspectors look at while inspecting an electrical panel is comparing wire sizes to circuit breakers sizes. When a wire is too small for a circuit breaker, you have a ...

In this episode of EC&M Code Conversations, Editor-in-Chief Ellen Parson and Code Consultant Russ LeBlanc contemplate a common concept that can sometimes cause confusion. When is ampacity not really ...

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 ...

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 ...

The development of utility-scale solar power plants is a costly and complex undertaking that requires extensive expertise to avoid pitfalls. Most solar project developers rely on debt financing to ...

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 ...
