Formula Used in “24V Wire Size Calculator”
The primary formula used in the “24V Wire Size Calculator” is based on the voltage drop across a length of wire and the current it carries. The standard formula to calculate the wire size is:
AWG = frac{{2 × L × I × R}}{{V_d}}
Where:
Standard Symbols
- AWG: American Wire Gauge, the standard unit used to measure wire thickness.
- L: Length of the wire run, in feet (ft).
- I: Current flowing through the wire, in Amperes (A).
- R: Resistance of the wire per 1000 feet, in Ohms (Ω).
- V_d: Acceptable voltage drop, typically a percentage of the supplied voltage.
Step-by-Step Breakdown of the Formula
To properly utilize the formula for determining wire sizes for your 24V applications, follow this structured approach:
- Determine Wire Length (L): Measure the total distance from the power source to the load and back (for a complete circuit).
- Calculate Current Flow (I): Identify the total current in Amperes that the circuit will draw.
- Find Resistance Value (R): Use a standard resistance table to find the resistance per 1000 feet (Ω) for the wire gauge being considered.
- Define Acceptable Voltage Drop (V_d): Choose an acceptable level of voltage drop; often, a value of 3% is acceptable for a 24V circuit, which corresponds to 0.72V.
- Input Values: Substitute the values for L, I, R, and V_d into the formula to find the AWG size needed.
Example Calculation
Let’s put this formula into practice with a real-world example. Suppose you have the following specifications:
- Length of the wire run (L): 50 ft
- Current (I): 10 A
- Resistance of 12 AWG wire (R): 1.93 Ω per 1000 ft
- Acceptable Voltage Drop (V_d): 0.72 V (3% of 24V)
Calculating AWG
Plug the values into the formula:
AWG = frac{{2 × 50 × 10 × 1.93}}{{0.72}}
This results in:
AWG ≈ 27.05
Since AWG is a standard and must be a whole number, you would round up to the nearest standard size, which in this case is 27 AWG. However, it’s practical to consider the next larger size, 26 AWG, to ensure the voltage drop remains acceptable.
Input and Output Table
| Input Parameter | Value |
|---|---|
| Length of Wire (L) | 50 ft |
| Current (I) | 10 A |
| Resistance (R) | 1.93 Ω/1000 ft |
| Voltage Drop Allowed (V_d) | 0.72 V |
| Calculated AWG | 26 AWG (safe for usage) |
