Not All Cord-locking Mechanisms Are Created Equal
Posted on 6/13/22 4:15 PM
Easy-to-disconnect connector locks and other cord-locking mechanisms are convenient tools for anchoring cords to inlets to prevent abrupt disconnects, but not all manufactured versions are created equal. Avoid easy-to-disconnect locking mechanisms which gouge or shave away the ground blade of the inlet during abrupt disconnects or improper usage and removal.

Calculating Voltage Drop
Posted on 11/15/21 4:12 PM
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.
