Assuming I already have a 30Amp breaker, Can I wire a 3 prong dryer outlet to this box?

>> No.2465392

To that box sure, but you will need to move the white from the neutral to the other phase on your breaker.

You will also need to mark that white as 'non neutral'

How does an amp work? Do you mean the 240v plug from dryers? Mine came with one luckily. Help me understand I'm stupid as fuck

need bigger wire. looks like 12 or maybe even 14 if im judging by the grounds. for a 30 amp 3 prong you need a 10-2. dont cheap out, thats how you set your house on fire. figure out a length of wire you need, add 10%, and buy it from a supply house.

Would it be easier to just go with a 4 prong outlet with the existing wire gauge? Wondering as the breaker box is a floor down and a ways away, I’d rather not run new line the whole way as there’s solid concrete floors, walls and ceilings.

The outlet for a dryer requires a 30Amp breaker at your electrical box instead of a 50 so it doesn’t overheat/cause a fire etc.

you cannot magically make a wire size work beyond it rating. you NEED larger wire for a 30 amp appliance. #10 is the size you need. its rated for 30 amps. that #12 or #14 thats there is not. the voltage dont mean shit. you have to use amperage rated wire and devices!

well what do you need? if the dryer is electric, its either a 3 prong or a 4 prong, which either requires 2 conductors and a ground, or 3 conductors and a ground. either way, you arent getting away from the fact that electric dryers usually require 30+ amp. look at an ampacity chart. if the wires are 14 gauge, theyre only rated for 15 amps. if they are 12 gauge, they are only rated for 20 amps. if you got a gas dryer, you could just run a 120v nema 5-15, but then you gotta run gas to the dryer.

run conduit on the outside of the building, or run MC on the surface indoors would probably be the easiest if you dont mind it looking ghetto.

Move dryer next to panel.

Yes, if you want to burn your house and kill everyone inside of it
I just don't understand these relentless niggers who are dead-set on killing themselves and everyone else in the building to save twenty minutes of mild effort
