We usually reply within a few working days.

If you are writing about a number, the fastest way to get it fixed is to say which table you checked it against — every calculator names its tables under How we calculate.

What we cannot do: tell you whether a specific installation is safe or compliant. We cannot see your panel, your terminals, your conditions of use or your local amendments, and a wrong answer to that question is not an inconvenience. That is what a licensed electrician and your inspector are for.
