Controls for the reclosers range from the original electromechanical systems to digital electronics with metering and SCADA functions. The ratings of reclosers run from 2.4–38 kV for load currents from 10–1200 A and fault currents from 1–16 kA. [7] [8] On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts.

As with Class C Shay locomotives, the tender rode on the third truck. Unlike the Shay, Heisler's design did not have a continuous string of line shafting running the length of the engine. Instead, the tender truck was driven by a line shaft above the shaft driving the main engine trucks, connected to it through spur gears.
The body and final assembly is by Grumman, and the chassis is made by General Motors, based on the 1982 Chevrolet S-10 Blazer, powered by GM engines including the 2.5-liter inline-four TBI Iron Duke and, in later production, 2.2-liter inline-four SPFI LN2; the instrument cluster and front suspension are similar to those used in the Chevrolet S ...
Tachometer showing red lines above 14,000 rpm.. The redline is the maximum engine speed at which an internal combustion engine or traction motor and its components are designed to operate without causing damage to the components themselves or other parts of the engine. [1]
Overspeed is a condition in which an engine is allowed or forced to turn beyond its design limit. The consequences of running an engine too fast vary by engine type and model and depend upon several factors, the most important of which are the duration of the overspeed and the speed attained.
The name DUKW comes from General Motors Corporation model nomenclature: [6]. D, 1942 production series; U, Utility; K, all wheel drive; W, tandem rear axles, both driven; Decades later, the designation was explained erroneously by writers such as Donald Clarke, who wrote in 1978 that it was an initialism for "Duplex Universal Karrier, Wheeled".
Caterpillar replaced the gross 3,550 hp (2,647 kW) [net 3,370 hp (2,513 kW)] Cat 3524B EUI 24-cylinder diesel engine used in the 797B with the gross 4,000 hp (2,983 kW) [net 3,793 hp (2,828 kW)] Cat C175-20 ACERT 20-cylinder diesel engine, enabling the 797F to maintain the 42 mph (68 km/h) top speed of the 797B while transporting a heavier 400 ...
