Welcome to our DC Cable Calculator, an essential tool designed to help you determine the correct cable size for your low-voltage electrical projects. Whether you're undertaking a campervan conversion, a marine installation, or any other off-grid system, using the right cable is critical for both safety and efficiency. Choosing a cable that's too small can lead to overheating, poor performance, and even a fire risk, while an oversized cable is an unnecessary expense. This calculator simplifies the process by considering key factors like current (amps), cable length, and voltage drop, providing you with a guided recommendation for your specific needs. If in doubt always consult a qualified electrician.
