changing dryer outlet from 3 prong to 4
There are basically two types of dryer outlets: 3 or 4 wire 30 amp 240 volt. The 3 wire was allowed by most codes before ~2000 or so, then the code changed to require a 4 wire outlet. The 3 wire has two "hot" wires (usually black and white) and a ground (usually green or bare copper).
Older homes typically have 3-prong outlets, but the National Electrical Code requires homes built after the year 2000 to have 4-prong outlets. While these same codes prohibit changing a 4-prong to a 3-prong outlet, the code does allow changing the dryer's cord to match the existing outlet regardless of whether the cord is 3- or 4-prong.
This cord converts a "standard 4-prong dryer outlet" into a 6-15 outlet. This lets me unplug the dryer and plug in a 220-volt cabinet saw.

A 4-pronged dryer cord will not fit a 3-pronged outlet and will require either an adapter or a change to a dryer cord that will fit the three pronged outlet. While adapters are a simple solution, it is recommended for safety purposes that the dryer's cord itself be replaced. The following items are needed to perform a cord change to a 3-prong cord:
A 3-prong dryer cord was the standard prior to 2000, at which point the National Electrical Code required 4-prong dryer outlets in all new home construction. Existing homes may still use 3-prong outlets. The switch to a 4-prong outlet was due to a flaw in the 3-prong outlet design.
