Residential Single Family Electrical Service Calculator |
Easy
to understand and use
Whether you are a home inspector, electrician, engineer, or a homeowner, you
can use this software and learn from it.
Most home
inspectors and many experienced electricians guess at the electrical service
size requirements using rules of thumb (usually involving only square footage).
With the rapid growth in the number of electrical appliances and electronic
equipment during the past few years, making a guess could be a costly mistake.
The Residential Electrical Service Size Calculator takes the
guesswork completely out of determining the electrical service size requirement.
The Calculator requires no special knowledge of electrical systems or codes.
All you do is make basic observations about the house and fill in the blanks.
The Calculator lets you enter electrical loads in either Amps or Watts.
the required information can almost always be found on the nameplates of
appliances and mechanical equipment.
The Calculator will tell the "Demand Load" (a trade term,
different from "connected" load), the nearest standard size panel and main
breaker, the conductor (wire) size and the conduit size.
The Calculator's worksheet can be filled out in about three to
four minutes and can be included with any inspection in PDF format.
Features of the Calculator:
-Automatically calculates the total demand load for a residential single family
dwelling
- provides the demand load in both volt-amperes and Amperes
- Automatically adds the minimum of small appliance and laundry branch circuits
- Automatically determines the heating and air conditioning demand load
- Determines the standard service panel size for the system
- Determines the service wire gauges in both aluminum and copper
- Calculations are based on the National Electrical Code (optional method)
- NEC section references under each heading
NOTE: This
worksheet is intended to be used as a general guide. It does not account for
all possible factors involved in determining the size of an electrical service.
Consult a qualified electrician or the NEC® for additional information.

Voltage, Current, and Power Calculator |
If you are thinking about pursuing your CMI designation,
you are thinking about doing commercial inspections, or you just want to be a
more knowledgeable home inspector, you need this calculator!
The area in which home inspectors
consistently score the poorest on standardized exams is electrical. Our
training calculators help you develop a better understanding of electricity and
electrical systems, thus, helping you to be a better inspector. Our calculators
also help you to develop the skills that your clients and the real estate
industry expect you to have as a CMI or a commercial building inspector.
The calculator is essentially an Ohm's Law
calculator. The difference between the
BestInspectors.Net
Voltage, Current and Power calculator and most Ohm's Law calculators is that
Ohm's Law calculators are usually geared toward electronics, not power systems.
This calculator is for power distribution systems. The calculator has a
Power Factor component to it. Most Ohm's Law calculators do not.
Calculations can be performed quickly and easily using name plate data or actual
measurements.
The calculator is also a training
calculator. There is a list of relevant electrical terms and units of measure
on the screen at all times. Every time you enter a value, the related terms are
highlighted. Once you have entered the values needed to complete the
calculations, the remaining input fields are blacked out so you don't
inadvertently enter a conflicting value. For example, if you have entered
Voltage and Wattage values, the Current input field is blacked out so you can't
insert an invalid value. The Current in this case would be among the calculated
values in the results section. |
