Cable Size Calculator:

When working with electrical systems, selecting the correct cable size is critical for safety and performance. The Cable Size Calculator helps you determine the right wire gauge based on your specific electrical requirements.

Whether you’re installing lighting systems, outdoor electrical wiring, or setting up power distribution, knowing the right cable size will prevent voltage drops, overheating, and ensure optimal power delivery.

How to Use the Cable Size Calculator:

Enter the current: This is the amount of electrical current (in amperes) flowing through the wire.
Enter the distance: How far the electrical current needs to travel, from the power source to the load or device.
Enter the voltage: The electrical voltage supply to the system.

Once you’ve entered these values, click “Calculate Cable Size” to get the required cable size in mm².

Why is Cable Size Important?

Safety: Overloading a wire or using a wire that is too thin for the current can lead to overheating, which could potentially cause fires.
Efficiency: Voltage drop occurs when the wire isn’t sized properly. This means the electrical devices at the end of the wire might not get the correct voltage.
Cost-Effective: An oversized wire is unnecessary, and an undersized wire is dangerous. Our calculator helps you find the optimal cable size for your system.
