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.
The Morse Code was developed by Samuel F.B. Morse in 1844. Even after more than 160 years, it is still used today, especially by amateur radio operators. The code can be sent quickly over the telegraph, and is also useful for emergency signaling (SOS) with a radio, mirror, or flashlight, and even for people with severe disabilities to communicate.
