Sum equations
The following tables list different equations that can be used for s umming voltage
and current values; the voltage methods are unrelated to the current methods.
The equations depend on the wiring configurations. In some c ases there are two
methods of using the sum voltage and sum current formulas: Method 1 or Method
2, as shown in the following tables. Use the method that meets y our needs.
