Calculator: Volt Drop in Cables


Posted by alistair on 01 Dec 2016 / 5 Comments



How much voltage am I going to lose along my cable? Just enter your info below to find out.

The calculator is based on twin-core Auto cable, so red & black together, for positive & negative, and sized in mm (not mm²).

There’s a Conversion Table (mm, B&S, mm²) and more info in the blog post How to Avoid Volt Drop in Cables

Sorry, reread your notes. NOT mm squared.

    Hi Chris,
    No worries – glad I could help you answer your own question!

    The conversion table can help to “translate” between the different standards.
    Cheers,

“Cable thickness “ is ambiguous.

Is it cross sectional area in mm squared ?

Thanks.
