Q: What is 4 prong?
A: Four Prong. Four prongs mean less metal on the diamond, letting the center stone be the star of the show. It gives diamond a more “squarish” look, making it a good choice for princess cut, cushion cut, and other diamonds that are square or rectangles.
Q: What size wire for a 220 volt outlet?
A: Most 220V tools require a 30 Amp circuit. That means you’ll need to run a 10-2 w/grnd to the outlet. 10-2 copper wire is normally good for up to 40 Amps on start loads and will sustain 35 Amps on constant load. All my tools that are 220V run easily on 10 guage wire.
Q: What is a 4 prong dryer cord?
A: The 4-prong dryer cord is comprised of two hot wires, a neutral wire and a ground wire. This creates a separate return path for unused current. Dryer cords are usually a maximum of six feet long as the code requires that an outlet be within six feet of the connected appliance.
