Calculating Voltage Drop for a 200 Amp Service
To determine the ideal wire size for a 200 amp service 200 feet away, we need to consider voltage drop. Voltage drop occurs when the electrical current faces resistance as it travels through the wires, resulting in a decrease in voltage. Various factors can influence voltage drop, such as wire length, current load, and wire material.
As per the National Electrical Code (NEC), a maximum voltage drop of 3% is recommended for branch circuits, while a maximum of 5% is recommended for feeders – the wires that connect the main service panel to subpanels or other equipment. In our case, we’ll focus on the feeder wires.
Wire Size Recommendations
Based on the NEC guidelines, let’s calculate the recommended wire size for a 200 amp service 200 feet away. Keep in mind that we’ll be using copper wire, which is the most common and efficient choice for residential applications.
Step 1: Determining the Current Load
First, we need to determine the current load, which is 200 amps in this scenario.
Step 2: Calculating the Voltage Drop
Next, we calculate the voltage drop using the formula:
VD = 2 * L * I * R / CM
Where:
– VD represents the voltage drop
– L is the wire length in feet (200 feet in our case)
– I is the current load (200 amps)
– R is the resistance per 1,000 feet of wire
– CM is the circular mils, which measures the cross-sectional area of a wire
Step 3: Choosing the Appropriate Wire Size
Finally, we need to find the wire size that meets the NEC’s recommended voltage drop. For a 5% voltage drop, use the table below:
| Wire Size (AWG) | Copper Wire Resistance (ohms/1,000ft) |
|—|—|
| 1/0 | 0.395 |
| 2/0 | 0.313 |
| 3/0 | 0.248 |
| 4/0 | 0.197 |
| 250 | 0.157 |
| 300 | 0.131 |
| 350 | 0.111 |
| 400 | 0.099 |
The Ideal Wire Size: 3/0 or 4/0 Copper Wire
Based on our calculations, the ideal wire size for a 200 amp service 200 feet away is either 3/0 or 4/0 copper wire. These wire sizes offer a low resistance, minimizing voltage drop and ensuring efficient electricity transmission. Remember, it’s always a good idea to consult with a licensed electrician to confirm the best wire size for your specific installation.
Now that you know which wire size to choose, you can confidently tackle your 200 amp service upgrade, no matter how far away it is. Good luck, and may your electrical system be forever reliable and spark joy in your life (but not actual sparks – that’s a whole other problem).
