Report a result you disagree with

The most useful reports include three things: what you expected, what you got, and the build identity shown in the footer. With those three pieces we can reproduce the result against the exact formula version you saw.

For your current session:

• Build SHA: 3150e0a6f096
• Formula registry checksum: a0471ccd8f3d

Suggest a calculator or reference

Wire Math is intentionally narrow and UK-leaning. If you work on UK installations and there is a routine calculation you keep running by hand, we want to hear about it. Tell us the inputs, the output you expect, and the standard or reference the calculation should follow.

What we cannot help with

We cannot give project-specific design advice, sign off installations, or interpret BS 7671 for a particular case. Those questions belong with a qualified electrician or designer working from the current regulations. See the disclaimer for the boundary.
