Yes, a #12 AWG conductor has a greater diameter than a #14 AWG conductor.
A #12 conductor has an ampacity of 20 amps whereas a #14 conductor only has an ampacity of 15 amps.

Can you wire 10 Gauge and 12 Gauge in the same circuit?
Yes but there are two stipulations, one that the join or splice must be made in a junction box that is accessible and has a removable cover and the second stipulation is that the breaker that is supplying the power can not be larger that the smallest conductor. In this case no breaker larger that a 20 amp breaker as #12 wire is only rated at 20 amps..
What gauge wire to use for dishwasher?
A domestic D/W uses 14 gauge wire.
Can you use 14-3 wire on a 20amp breaker?
No. A 20 amp breaker needs 12 gauge wire.
Is it safe to use 10 gauge wire on a 20 amp breaker for a microwave?
No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.
How many watts is a 240 volt 20 amp fuse rated for with 12 gauge wire?
4800
Is 20 gauge iron wire thicker than 21 gauge?
No, the higher gauge means a thinner wire.
Which is larger 12 gauge or 20 gauge?
12
Which is thicker 12 gauge or 20 gauge?
12 gauge is thicker than 20 gauge. The lower the gauge, the thicker the sheet metal or wire.
How big of a single pole breaker can you put on 12-2 wire?
In general, you should never use a breaker larger than 20 Amps on a #12 AWG (American Wire Gauge) copper wire.
What type of wire gauge should be used for a 20-amperes circuit?
Yes, 12 AWG is good for 25 Amps if copper wire.If aluminum wire, then good for 20 Amps.
Does a 20 amp circuit require a number 12 gauge wire?
12 guage wire israted for 20 amps and 10 guage is rated for thirty amps! 12 gauge is what is required, as it is rated for 20 amps. 10 gauge is rated for 30 and will be more then enough. Oversizing wire in your case isn't necessary. The thicker 10 gauge wire is harder to work with and will more then likely cost more.

What gauge wire to use for dishwasher?
A domestic D/W uses 14 gauge wire.
What gauge wire is used on a 20 amp breaker?
AWG 12.
Is the wire gauge smaller from the battery to the fuse box and larger to the air coditioner?
Yes, the wire gauge numbers are smaller. A typical automotive battery cable would be 4 gauge, the wires after the fuse box would be 10, 12, 14, 16, 18 and 20 gauge depending on the accessory.
Can 15 amp rated outlets be used with twelve gauge wire?
A. It's 240 volts & B. Wire size is a function of amperage. 12-gauge wire is used with 20 amperes or less. So, 12-gauge wire can be used with 120V/20A or 240V/20A. Keep in mind though that 240V in the U.S. has 2 live 120V lines so if you encounter a white wire, it's probably an unmarked live & should be repainted as black or better yet, red (to indicate the 2nd live wire).
What gauge needed for 20A?
The guage of wire for 20 amps is #12 copper.
