How can I tell if I have 110 or 220 voltage in my house (for an insurance form)?

Question

I looked at the circuit breaker box, but all I saw mentioned was 240 volts.
Thank you.

I've checked the circuit breaker box, but only thing I see mentioned is 240 volts. My house was built in 1948, but apparently updated to circuit breaker at some point.

Answer 1

240 is the correct terminology. It means the same thing as the old 220 phrase. Almost all homes have a 240 volt service.

Answer 2

You didn't say if you took the cover off the panel box or not. Or if it had a main circuit. breaker. If the main breaker looks like two circuit breakers are together by the handles, then I would say the you most likely have a service that is 240/120 volts. They might also be looking to find out if you have a 100 amp service or if it's a 200 amp service. That would be marked on the Main Breaker. If you have a disconnect between the meter and the panel that would tell you the amps the panel is being feed. It could be a circ. breaker or fuses. If there are two fuses then I would say that it 240 volts. the fuses or circ. breaker would also tell you the amps coming into the house.

Answer 3

Most houses are wired for both 240 and 120 volt circuits.
The transformer outside on the utility pole has a 240-volt
winding that is center tapped producing two halves, each
of which has 120 (not 110) volts. The 240-V circuit is used
for high-power appliances like air conditioner, range,
water heater, etc. The 120-volt circuits are used to power
lights, fans, radio, TV, and the like. This is normal, and you
can put down 240-volt on your form since that is written on
the breaker box. (P.S. I don't know where people get the
myth about 110 and 220 volts; I have measured it many
times with a voltmeter and it is closer to 120 and 240.)
Hope this helps.

Answer 4

As others state you have both 110 and 220; with the 110 split off for appropriate uses. Most breaker boxes state the max AMPS; not volts. Your breaker switches show what amp rating is being used by what appliance of circuit perhaps connected to multiple switches and receptacles.

Clothes Dryer/ oven/ Central heat/AC are 22 and often on a double breaker. Lights are on 100 breakers; often rated at 20 AMPS and usually carry an entire room; or more.

Answer 5

IT is 240 volts

But i am guessing they will want to know the service size. 200 amp 150, 125, 100, 60 are the norm. If you have fuses instead of breakers you may take a hit.

Switched mine to a bigger breaker panel and got a cheaper rate.

Answer 6

In the U.S. 220 and 240 are two common names
for the same voltage system.
If the panel says '240`, go ahead and check
the '220` box on the form.

Answer 7

You have both, each line coming in is 120 v. Right side of panel is 120, so is left. If you have a 240 breaker it installs on one side but bars in panel to give you 240 volts. What their probably asking is if you have a 240 breaker in service for a major appl. like stove , elec. dryer

Answer 8

Household voltage in the US is 110 - 120 volts. You could have 220 or 240 volts for electric range, electric oven or clothes dryer.

Answer 9

All homes have 220v , the question on the form may be how many amps you have coming in that is usually the question they ask, you can find this on the main breaker in the panel or outside usually 100 amp or 200 amp

Answer 10

When you look at your breakers, you should see some that are singles and some that are doubles.
The singles would be 110; the doubles, 220
