Yes you can. The existing 30 amp breaker on the two conductor #10 wire will have to be changed out to a two pole 20 amp breaker. The reason for this change out is that the new 20 amp outlet is only rated at 20 amps maximum. If the 30 amp breaker were left feeding the 20 amp device, It would be unsafe as it is 10 amps higher that the manufacturer's specifications of maximum amperage handling capacity of a 20 amp device.
If the 30 amp circuit is only 120 volts, the neutral will have to be lifted from the neutral bar of that circuit and that will be the second wire that will be connected to the new two pole 20 amp breaker. This action will give you 240 volts across the new 20 amp outlet.

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
How do you you change a two wire recepial without a ground to a two wire with a ground?
Shut the power off to the recepticle. Then take apart the old outlet. Wire up the new outlet. The only difference between the old and the new will be the grounding. If BX armour cable is used, then you will need to take a jumper wire from the grounding nut on the outlet and connect it to the box with a grounding screw. This wire must be green. If romex has been used, then there is a gounding wire that is in the bundle of the wires coming into the box. If it a metal box, then you must use a grounding screw and ground that wire to the boc and then connect that same wire to the outlet. If its a plastic box, then just wire the ground to the outlet. I also like to wrap the outlet in electrical tape, just incase the the wires were to come loose, they would note hit against the box shorting out. Finally, put the pieces back together. And your DONE!
WDR type outlet?
A fire trap outlet used in motor homes. The wire self pierce romex conductors with a small contact friction contact. These should be replaced with quality screw terminal outlets in outlet boxes.
How do you connect 3 wire to 2 wire 240volt's I'm trying to remove the washerdryer outlet and branch four 240v receptacles from the 240volt 3 wire outlet?
just leave the neutral wire as it is and connect the other two !!
How do you wire a 3 wire exhaust fan to a 4 wire outlet?
The fan is probably a 115 VAC single phase fan and the outlet is probably a 230 VAC "two phase" outlet. The fan would then have the following wires: hot (black), neutral (white), and ground (green). The outlet would then have the following wires: hot #1 (black), hot #2 (red), neutral (white), and ground (green). Pick either of the two hot wires on the outlet and connect the hot wire of the fan to that (ignore the other hot wire on the outlet) and connect the neutral to neutral and ground to ground. If the wire colors are not as I described above you may have something else (e.g. 3-phase) and that would be wired differently, but those systems are usually used only in industrial settings not the home.

You don't.

Can it be dangerous to wire one outlet of a double outlet to a switch?
No, that is not unsafe.

Can a receptacle be used as a splicin device?
If you mean can you split off the power from an outlet to another outlet or device the answer is yes. Just make sure not to overload the circuit. Usually outlets have two connection points for Hot (Copper colored screw) - black wire and Neutral (Silver colored screw) - White wire. Just take off power at the unused screws if they exist or use wire nuts to branch off other wire pair and a pigtail to reconnect to the outlet if two pairs of wire already on outlet
Why does a newly installed GFCI outlet show open ground on the tester?
Ground wire is loose or disconnected somewhere in that circuit.
What size wire do you use if you are require to wire a 6-20amp 220volt outlet?
# 6 wire
How do you wire a circuit so that the switch only controls the second receptacle and the first receptacle is always energized?
You will need a receptacle that you can wire each outlet separately (not jumpered). You would then wire the switch in series on the line conductor with the outlet you want switchable. Wire the other outlet directly to the power source. You can jumper the neutral from one outlet to the other.
Can you wire a switch from an electrical outlet?
yes
