Traditional machine hardwiring involves a virtual maze of wires and cables. In modern machine setups, electrical, signal and data contact points can number into the hundreds for complex operations or multifunctional machines.
Electronics manufacturing uses a LOT of resources – on average, 1.5 tons of water, 539 pounds of fossil fuels, and 48 pounds of chemicals are needed to make one computer and one monitor (Wang, 2017). With more than 500 million computers, monitors and tablets sold to consumers last year, those resources add up.
Ground fault circuit interrupters (GFCIs) are used in wet and hazardous settings and have proven to be a life-saving technology. A GFCI disconnects a circuit when it detects that the electrical current is not balanced between the energized conductor and the return neutral conductor. An imbalance can indicate current leakage through the body of a grounded person who accidentally contacts the energized part of the circuit. GFCI devices disconnect quickly enough to prevent injury.
