When designing an electrical circuit it's common practice to go piling into calculations to figure out breaker ratings, cable sizes and similar.

However there's some important information to gather before you go down that road.

We take a look into the various books that give advice on electrical design, including BS 7671 The Wiring Regulations, the On-Site Guide and The Electrical Installation Design Guide published by the IET.

Take a dive with Joe into the exciting world of electrical design in this series of videos that will help you if you're just starting out in this area at college or work. Even if you've been an electrician for years, there's something for everyone in this series of videos.
