i'm going to be buying a welder soon and i need to run a 220 volt out let off my main panel (in the garage) out let will be below the main panel.

i under stand 220 wirering some what my question my main panel only hase one space left can i use a Tandem Breaker breaker in this spot for 220.

the breaker looks like this

can it be done? i think so... fill in the gray area for me

You have to look at the specs of panel to see if allowed.Should say on there somewhere.

 

[tcgreaux]

were would i find that and what would they say

That is a twin/tandem/skinny breaker, not a two-pole breaker. That breaker will NOT give you 240v. It will give you two 120v circuits.
You need TWO spaces for a 240v circuit.

IF, and only if, your panel will accept twin breakers you can use one to free up a space in your panel by consolidating two 120v circuits to one space. Even this has risks so be sure you know what you are doing first.

 

[Speedy Petey]

Also, what size circuit do you need? "220" means nothing without more info.

The circuit you need will be 240v at a certain amperage. The amperage is the size of the circuit.

 

[tcgreaux]

230v @23 amps the welder requires

op said he has 1 space left emty.With that twin that will free up another space with the one he has alredy so he will have room for 2 pole breaker

Sould show list of breakers you can use on door of panel (bad pic)

No it can not be done. A double breaker only connects to one leg of the service a 220 break connects to both legs.

 

[tcgreaux]

what does the two pole do that makes it 240volts that cant be acomplished with he tandem (just want ot under stand) and my box almost has all tandem breakers except for two Arc-Fault Circuit Interrupters . and 4 240v double pole

 

[hayewe farm]

Every other slot is on a separate leg a 240 volt break takes up 2 slots so it is connected to both legs rather than one.

 

[tcgreaux]

No it can not be done. A double breaker only connects to one leg of the service a 220 break connects to both legs.

ahh ok so eachs tab going down the box is ever other leg as in
(leg A-leg B-leg A-leg B)
i think im geting how it works

 

[tcgreaux]

so i would most likly have to run a sub panel?

 

[hayewe farm]

You might use the double to replace a two 120 volt breakers thus freeing up another slot and install a double breaker.

 

[tcgreaux]

all of the 120 are doubles not including 2 Arc-Fault Circuit Interrupters 1 for the dish washer 1 for the disposal

 

[300zx]

To get 220 you need to have a 2pole breaker that falls on the 2 seperate bus bars

 

[tcgreaux]

now i dont ue my dryer all the time could i tie in to that 240v to use for my welder just have tonot use the dryer while welding right?.

 

[300zx]

You say you have 4 220 breakers? what are there size?

 

[300zx]

You could get a quad breaker if you had like 2 2pole 30's you could get a 30/30 quad takes one space for 2 -2 pole breakers another bad photo. I know one is broken.

 

[tcgreaux]

just check i have 5... 1 range both 50 amp, 2 ahu (im gessing air handler) both 45 amp, 3 a/c both 35, 4 w heater both 30, 5 dryer, both 30
