do all breaker boxes have the ability to supply at least one 240 output source?

Answer 1

The determination is in your service drop, the conductors coming from your utility provider.

If your service drop is overhead and you have three conductors connected thru fusible links to your service, you have 240V single phase available.

Answer 2

All breaker boxes have the ability to supply 240 volt circuits. But once they are installed, it depends how they are connected. Try being a little more specific about what you want to know.

Answer 3

If your breaker panel has two rows of breakers it is OK for a 220 volt source the way that is done is on the main there is the service line which feeds each side of breakers.
Now understand this, the top two breakers are served by different phases so as you go down the breaker panel every other switch is phased opposite of the other.
this is why on a 220 supply you have the 220 volts supplied by breakers that are side by side.
Unless you house was built pre 50's you have 220, I bet money on it...

Answer 4

Back when most home services were only 30 amps and provided only 120. With the advent of several new appliances and electrical devices the home service panel had to be increased to 240 to meet the demands of the increased circuits required in the home. Today several 240 circuits in the home are the norm like,water heater,air conditioning and more unless for a special application I would say yes to your question, providing we are talking of the current day service panel.

Answer 5

No. Only if it has 240 v. run to it. I have 240v. to my house. From there, a 120 v. service runs to my garage.

Answer 6

Most do.
Some very old ones are 120V. only.
