Over the next series of pages, I have detailed various useful electrical calculations. These have mainly been sourced whilst studying for my City & Guilds 2330 qualification and should be fairly accurate.

However, please consult a qualified electrician before using any of these calculations as I cannot be held responsible for any miscalculations or errors encountered because of them. They are represented here purely for educational purposes and should not be used in real life electrical calculations unless you know what you are doing.

With that said, here are the current calculations available.
