Sizing conductors to prevent excess voltage drop


Step 1: Phase Specify whether the calculation is for single-phase (1∅) or three-phase (3∅).
1.1	Phase	Single-phase (1∅) Three-phase (3∅)
Step 2: Wire Select the appropriate information on the medium being used.
2.1	Wire material	Copper Aluminum
Step 3: Load This satisfies I and D.
3.1	Load at 100%	Volts
3.2	The distance of the load from the power supply
Step 4: VD Input the Voltage Drop Requirement
4.1	VD
Step 5: Solve
5.1	Proof steps	Show proof steps
5.2	Solve for Circular Mils
