When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

For an efficient design, the conductor ampacity tables in Chapter 3 of the National Electrical Code (NEC) provide a starting point. But did the installation stay efficient over time? One way to ...

Despite the widespread availability and use of low-power components, today’s printed circuit boards (PCBs) can require a significant amount of current, with boards drawing 50, 100, and even 200 A in ...
