A 6-20R is 220V, 15/20A correct? If the outlet is within 75ft of the panel you need to run 12-2 to the outlet from the panel. I would recommend 12-3 as you can then upgrade to a 120/240V outlet later and you are not using a white wire as a hot. If you do use 12-2 wrap the white wire with electrical tape to show it's not neutral. Then just wire the outlet as a normal 220V outlet to a 20A 220V breaker.

BlakeTo wire a 6-20R outlet, connect the black (hot) wire to the brass screw terminal, the white (neutral) wire to the silver screw terminal, and the green (ground) wire to the green screw terminal. Make sure to secure the wires using the appropriate wire connectors and tighten the terminal screws. Always ensure the power is turned off before working on electrical outlets.

How does the white wire on an outlet become hot?
a shorted out outlet can cause a backfeed on the white wire, an open circuit on the white wire with and electrical appliance plugged in to an outlet can cause the same type of backfeed
Do you run the wire above or below outlet boxes?
The wire should run above the outlet boxes. This is to ensure that the wire is easily accessible for future maintenance and repairs without having to dismantle the outlet boxes.
How do you wire two outlets together when you want to continue the run to another outlet?
To wire two outlets together and continue the run to another outlet, you can connect the incoming hot wire to the brass-colored terminal on the first outlet, then connect a short jumper wire from the first outlet's silver-colored terminal to the brass-colored terminal on the second outlet. Finally, connect the incoming neutral wire to the silver-colored terminal on the first outlet and repeat the process for subsequent outlets in the circuit.
Can you wire a switch downstream from an outlet?
Yes, you can wire a switch downstream from an outlet by connecting the switch to the hot wire (black) from the outlet. The hot wire would then be interrupted by the switch before continuing to the outlet, allowing you to control the power to the outlet with the switch. Always ensure to turn off the power before working on any electrical components.
What if you have four wires running to your dryer outlet and the outlet is only a three prong one wire is just hanging out is this really even safe?
No, it is not safe to have a wire hanging out of an outlet. If you have a four-wire connection but only a three-prong outlet, this could pose a safety hazard. You should have a qualified electrician properly install a matching outlet to avoid any risk of electrical shock or fire.
