IET Wiring Regulations Lite is an app for IET Wiring Regulations 18th Edition with a 2022 Amendment. It is the perfect companion for a busy electrician who needs to prepare for the IET WIRING REGULATIONS EXAM, C&Gor or simply want to improve and update his knowledge of the Wiring Regulations.

It has been designed as an exam-like app, which means that it includes questions based on the latest changes made to the Wiring Regulations such as the new requirement for Arc Fault Detection Devices (AFDDs) in some AC final circuits for installations in some types of higher-risk residential buildings; the new fire safety design of buildings to be documented where specific conditions of external influence exist, such as protected escape routes and locations with risk of fire; the method for determining the requirement to provide over-voltage protection; changes to identification, labels and notices, such as for consumer units, affecting how safety information is provided to the user of the electrical installation; and a new part, part 8, containing over 500 exam-style questions.

It also has mock test mode, which allows you to choose from possible answers. You can get the result for each question you answer correctly and where you were wrong. The app is very interactive and needs minimum user input.
