These resources were created by Sam Nason as part of a collection of learning and revision materials developed throughout my three years at college studying electrical installation and electrotechnical engineering.
These resources were originally created to support my own learning and revision. I have since updated and adapted them to share with other electrical learners who may find them useful.
These resources are intended for educational and revision purposes only and should be used alongside appropriate practical training, supervision and current industry guidance.
