VoltCheck24 Engineering Calculator

DC Wire Size Calculator

Select a practical conductor size for DC control wiring by checking current, distance, voltage drop limit, and installation margin.

Open Wire Table Calculate Voltage Drop

What It Solves

Quickly compare AWG and square-millimeter conductors for control power, sensors, actuators, and small DC loads.

Decision Criteria

Do not size wire from ampacity alone. Check terminal voltage, voltage drop percentage, ambient temperature, bundling, and protection device coordination.

Output

Use VoltCheck24 to pair conductor selection with voltage drop review, BOM preparation, and technical report export.
