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 ...

Do you know where to find the voltage drop rule in the NEC? That’s a trick question. The NEC has many rules. Some rules are mandatory [90.5(A)] (you must comply), and others are permissive [90.5(B)] ...

Using longer cord lengths in an electrical design can introduce challenges significant enough to create potential safety risks. When cable lengths reach 50 feet or more, voltage drop becomes a concern ...
