Electrical Calculations and Formulas

Voltage Drop Calculations
Voltage drop is an essential factor in determining the correct wire size to prevent voltage loss which will occur in long distance runs of electrical wire or cable.

Electrical Power Calculations
Electrical power calculations are required to determine the initial load requirement for any given circuit. Power Factors are identified and taken into consideration as well to maintain safety for circuit integrity and performance.

Voltage Drop Calculations
*Disclaimer
Other electrical projects will require extensive consideration when it comes to voltage drop due to the length of the electric service or generator sizing especially when motors will be used, such as well pumps.

To assist you in the planning process I have selected a few resources to help you in the calculation process that I find very helpful.
