Unfortunately I didn't purchase this off Amazon, as I could have saved a few bucks ($7.00). Having just purchased a spa/hot tub I needed the 50 amp GFCI, and adding a separate panel with GFCI was less costly than trying to get a 50 amp GFCI breaker to add to my current panel (Cutler-Hammer). The wiring was pretty simple - although using #6 wire is never easy.
Spindle nose on a lathe headstock. The small female taper is a Morse taper to take a lathe center or a tool such as a twist drill. The large male taper takes a lathe chuck, which is retained by the large nut. A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool. A male member of conical form (that is, with a taper) fits into the female socket, which has a matching taper of equal angle.
Potentiometer, single turn, 5 kÎ© to 50 kÎ©, linear taper (Radio Shack catalog # 271-1714 through 271-1716) Potentiometer, multi turn, 1 kÎ© to 20 kÎ©, (Radio Shack catalog # 271-342, 271-343, 900-8583, or 900-8587 through 900-8590) Potentiometers are variable voltage dividers with a shaft or slide control for setting the division ratio. They are manufactured in panel-mount as well as breadboard (printed-circuit board) mount versions. Any style of potentiometer will suffice for this experiment. If you salvage a potentiometer from an old radio or other audio device, you will likely be getting what is called an audio taper potentiometer. These potentiometers exhibit a logarithmic relationship between division ratio and shaft position.
