The load-wiring-calculator will give you a very simple and quick solution to the problem of calculating the size of wires and DC maximum load for LED power transmission.

Calculate which wire guage is best to use for a given voltage drop limit and wire length.

This is a calculator for the estimation of the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current.

**Voltage Drop = (WL x 2) x R x LC / 1000**

**Voltage Drop % = (Voltage Drop / SV) x 100**

Where:

WL = Wire Length

R = Resistance

LC = Load Current

SV = Source Voltage

Calculates the maximum wire length of a single round wire of common conducting materials using the formula below.

**Wire Length = ( VD x 1000) / (LC x 2 x R)**

Where:

VD = Voltage Drop

LC = Load Current

R = Resistance

The resistance is then matched to the corresponding wire gauge value as per the American Wire Gauge standard (AWG).

Calculates the Resistance of a single round wire of common conducting materials using the formula below.

**Resistance = (VD x 1000) / (2 x WL x LC) **

Where:

VD = Voltage Drop

WL = Wire Length

LC = Load Current

The resistance is then matched to the corresponding wire gauge value as per the American Wire Gauge standard (AWG).
