I've seen the service entering very old homes without updated wiring to be 120v/30A. This was in a very old home wired in 1946. Homes in the 60's were being wired 120V/240V with 100A-150A services. Homes in the late 70s and early 80s were being wired with 200A services. In a lot of cases, this was to accommodate the use of all-electric appliances, including baseboard heat and water heaters. A few months ago, I helped wire a house with 2-200A breaker panels, with a 100A sub-panel in the garage. I've also heard of new larger homes being wired for 400A, 800A, and more. The sky is definitely the limit. For branch circuits: the amp ratings are generally 15A, 20A, 30A, 40A, and 50A.

∙ 13y agoImpossible to tell without a meter. Most homes are wired with a 60amp or 100amp (max) Panel. Checking how many amps are being drawn off a main hot wire should do the trick.
Another perspective Actually... a house doesn't consume any electrical energy. The only way to use electrical energy is to turn on appliances or other electric devices.To determine the amperage consumption of your house, add the total amperage draw of all electrical devices that are on at any one time.

What is the typical amp draw on a low voltage circuit?
2 amps
How do I know if I have a 30 amp breaker at my house to plug a trailer into?
If it is a 30 amp breaker then it is a 240 volt outlet.
What is a common branch circuit connector?
There are many variables that affect the ratings of electrical circuits but in general: If you are asking about residential branch circuit ratings, they are listed in amps and protected by a fuse or breaker. For example, a typical residential lighting circuit is usually a 15 amp / 120 volt circuit. It will be protected by a 15 amp overcurrent device (breaker or fuse) and all components of the circuit (wire etc) must be rated for at least 15 amps. Common residential circuit ratings: 15 amp / 120 volt - lighting and receptacles 20 amp / 120 volt - bathroom, kitchen, dining room, workshop etc. receptacles 30 amp / 240 volt - electric dryer, electric water heater 40 or 50 amp / 240 volt - electric stove For minimum conductor (wire) sizing, the National Electric Code recognizes many variables that affect the ampacity (number of amps) a wire can safely carry. But in most residential circuits the following copper conductors are used: 15 amp - #14 American Wire Gauge (AWG) 20 amp - #12 AWG 30 amp - #10 AWG 40 amp - #8 AWG 50 amp - #6 AWG Aluminum is typically not used in the smaller sizes, though you may find #6 AWG used for larger (40 amp) loads
What is the current supply to a house amp?
Most modern homes in the United States operate on 100 to 150 amp systems. Some larger homes have 200 amp or larger systems.
What type of circuit and or breaker should a typical consumer-sold hot plate rated at around 1800w with 2 burners for 120v ac be plugged into - will typical kitchen countertop plugs do?
1800 watts will require a 20 amp circuit. Kitchen countertop outlets are usually, but not always, 20 amp circuits.
How do you calculate the size of cable according to current?
First determine the amperage of the circuit . e. g 15 amp or 20 amp ( typical household circuit ratings) the gauge is 14 and 12 respectively. The lower the gauge number the higher the current handling capability.
What is the typical amp draw on a low voltage circuit?

Can you mix batteries with differing Amp Hour Ratings?
yes
What size wire do you need for a forty amp breaker?
8 AWG is typical.
What is all the Fuse able link amp ratings for a 1985 Pontiac Fiero GT Engine?

How many amps does a windscreen wiper motor take?
They do vary, but 1.5 amp running 2.5 amp stall are the common ratings
What are the dimensions of a car amp?
The dimensions of a car amp vary depending on the supplier of the amp and model of the car. Typical dimensions are around 2.25" x 9.88" x 20.25" though they can be found both bigger and smaller.
How do I know if I have a 30 amp breaker at my house to plug a trailer into?
If it is a 30 amp breaker then it is a 240 volt outlet.
Is the 30 amp breaker for a motorhome the same as for a house?
Yes, a 30 amp breaker is a 30 amp breaker. It must however be able to fit the box it is installed in.
What is the demand factor for 7 30 amp sites and 3 50 amp sites in a RV park?
The CEC states; 100% of the sum of the first five receptacles having the highest ampere ratings and then 75% of the sum of the ampere ratings of the next ten receptacles having the same or next smaller ratings.
