The load-wiring-calculator will give you a very simple and quick solution to the problem of calculating the size of wires and 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).
