Calculating Voltage Drop is Critical in the Application of your Electrical design. Using longer cord lengths in your electrical design may become problematic enough to pose potential dangers. When cable length is 50 feet or longer, voltage drop in cable occurs—the resistance in the copper measured per foot—causing heat buildup.

In an InfoPower article posted on March 15, 2021, “Importers of Chinese Electrical Cord Sets and Components May Continue Experiencing Gridlock,” Interpower noted the rising costs of shipping containers, specifically that the rate of a container shipping from Asia to Europe in November of 2020 was $2,200. In February of 2021, three months later, that same container cost $7,900.

Stacks of shipping containers continue to rise skyward at many U.S. seaports, especially on the Pacific Coast. While COVID quarantines and lockdowns that began in early 2020 are responsible for much of the slowdown, some costal states remain cautious in opening up commerce in a safe but timely manner as many lockdown rules remain in place.

A socket strip is a stand-alone electrical product containing several power sources (sockets) to provide equipment electrical connectivity by way of a country-specific AC input cord. Socket strips allow one or several machines to receive power in one or multiple strips.

A module is a device that combines multiple functions into a single unit to control power entry. There are several reasons to choose a module over individual components that are installed piecemeal. When choosing a module in your design, the first step is deciding which functions or components your module should contain. Typically an Interpower module offers two to five functions: an inlet, outlet, switch, circuit protection, voltage selector, and a filter.
