12-2 (#12-2 conductor) wire doesn't "pull" 20 amps. However, it's ampacity rating is that of 20 amps. #12 copper wire is rated for a total load of 20 amps. So, always use a 20 amp breaker with it.

What wire size in a 20 amp 250 volt circuit?
The wire rating for a # 12 wire is 20 amps. If you are going to continuously load the circuit you need to de-rate the wire by 80%. This brings the current down to 20 x .8 = 16 amps. The wire rating of a # 10 wire is 30 amps. 30 x .8 = 24 amps.
What size wire should you use for a 20 amp breaker?
A #12 wire is rated at 20 amps, continuous loading at 80% = 16 amps. # 10 wire is rated at 30 amps, continuous loading at 80% = 24 amps.
What is amperage limit of 12 AWG stranded copper wire?
A #12 copper wire with an insulation factor of 75 or 90 degrees C is rated at 20 amps.A 12 AWG wire should not be connected to a breaker larger than 20 amps. The wire is capable of carrying that current load without overheating and causing fire.
How do you calculate a sises of cable used for an appliance?
Wire sizes and ampacity are regulated by code. # 14 wire 15 amps, #12 wire 20 amps, #10 wire 30 amps, #8 wire 40 amps, #6 wire 60 amps. These are the most common, a slight variation in amperage depending on the insulation factor.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker

How many amps service does 12 gauge yellow wire hold?
The normal current capacity of 12 AWG copper wire is 20 amps.
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.
How many amps can a 2.5 sq mm wire conduct?
It will taken 8 amps <<>> The conversion of 2.5 sq mm wire to AWG is equal to a #12 wire. The ampacity of a #12 copper wire with an insulation factor of 90 degrees C is 20 amps.
How many lights on 20 amp circuit?
Provided you use wire that is rated for 20 amps.
How many amps for 14 wire how many amps for 12 wire?
#14 copper wire is rated at 15 amps, # 12 copper is rated at 20. The maximum capacity of any wire is 80% so remember to derate your current by multiplying the rated current by .8
