Central air conditioning also runs on 230 volts. However, because they are permanently mounted, central air units are hard-wired into your electrical box. A typical 2-ton central air unit that puts out 24,000 BTUs will draw between 15 and

**20 amps**.Similarly, it is asked, how many amps is a residential service?

Most breaker boxes are 100,

**150**, or**200 amps**. Add the amperages of all the individual breakers in the box. The total may be more than twice the total amperage of the box. For example a**100**-amp service panel may have circuit breakers that add up to more than**200 amps**.How many amps are in a wall outlet?

Most modern residential circuits are

**15**or**20 amps**, so we're looking at a max load of either (15A x 120V =) 1800 watts or (20A x 120V =) 2400 watts before the breaker trips. The breaker will be labeled either**15**or**20**.How many volts do you need to power a house?

The bare wire is the ground wire. The two insulated wires each carry

**120 volts**, but they are 180 degrees out of phase so the difference between them is**240 volts**. This arrangement allows a homeowner to use both**120**-volt and**240**-volt appliances.
