House Load Calculator List Of Appliances
House load calculator list of appliances is quick with WireGaugeCalc, which builds a dwelling demand total from each appliance you enter.
Add the range, water heater, dryer, and other fixed loads, and the tool applies the right demand factor to each group.
You get a running total in amps, so the list turns into a service size you can act on.
Open the calculatorEnter any two values and read the rest.
Ohm’s law: V = I × R and P = V × I. Field aid only, verify against the current NEC and your local authority having jurisdiction.
Turn an Appliance List Into a Demand Total
Each appliance enters as a fixed load, since the NEC groups them for demand-factor treatment once four or more are present.
The range and dryer use their own demand rules, so the calculator handles them apart from the general fixed-appliance group.
The list feeds a single total, so you can compare it against a 100 amp or 200 amp service.
Common Appliances on the List
The total grows as you add the usual dwelling appliances:
- Electric range or cooktop and oven
- Electric water heater
- Clothes dryer
- Dishwasher and garbage disposal
- Heating or air conditioning, whichever is larger
One app for every NEC calculation
WireGaugeCalc keeps the calculations you reach for most in one place:
- Voltage drop and wire sizing for any run
- Conduit fill for EMT, PVC, and RMC
- Box fill and junction box sizing
- Ampacity and temperature derating
- Motor circuit and load calculations
- Conduit bend offsets and saddles
Built for the field, works offline
The whole app runs on your phone, so it keeps working in a basement, an attic, or a job site with no signal.
There is no account to create and nothing to load. Open it, run the number, and get back to work.
- No signup and no signal needed
- Answers in a tap, not a spreadsheet
- Same tool on phone, tablet, and desktop
Every result cites the NEC article
Each answer shows the table or formula it came from, so you can check the method and learn the code as you go.
That makes the app useful on the job and during exam prep, since the reasoning is right next to the number.
Switch the code year your job runs on
Jurisdictions adopt the NEC at different times, so you can match the calculation to the code in force:
- NEC 2017, 2020, and 2023 tables
- Copper and aluminum conductors
- 60, 75, and 90 degree C terminations
- Single-phase and three-phase systems
Run the number, then get back to work
Stop flipping through a paper book or hopping between calculator sites. Enter your values, read the code-cited answer, and move on. Free to use, no signup.
Open the calculatorFrequently asked questions
Does the dryer get the same demand factor as other appliances?
No. An electric clothes dryer has its own minimum load and demand rule, so it is figured apart from the fixed-appliance group. The calculator applies the dryer rule when you add one to the list.
How many appliances trigger the fixed-appliance demand factor?
When four or more fixed appliances are on the service, a demand factor reduces their combined load. Verify which appliances count against the current NEC and your local authority having jurisdiction.
Is WireGaugeCalc free to use?
Yes. Every calculator is free to run with no signup. A paid tier adds saved projects, PDF reports, and extra code years, but the core math stays free.
Does it work without internet?
Yes. The app runs on your device, so it keeps working with no signal on a job site, in a basement, or in an attic.
Are the results code accurate?
Results follow published NEC tables and standard formulas, and each answer shows the article it came from. It is a field aid, not a stamp of approval, so verify against the current code and your local authority before you wire anything.
Which NEC code year does it use?
You can switch between NEC 2017, 2020, and 2023, since jurisdictions adopt the code at different times. Pick the year your job runs on.
