It is a requirement of the Wiring Regulations that electricians measure the earth leakage currents in an installation upon completion of their work.
By testing that the earth leakage is within acceptable limits we can have more confidence that the installation will not suffer from unwanted or nuisance tripping.
Many electricians, however, do not fully understand all the requirements and implications of the Wiring Regulations, so this video has been compiled to help everyone have a greater understanding.
An electrician will often be called upon by a customer with an RCD that is tripping every day, every evening and so on. The electrician may carry out certain tests in an attempt to uncover the cause, but may miss certain vital clues because the tests are not carried out fully.
In this video we hope to address those issues and hopefully help you to gain more knowledge in order that you can confidently approach those nuisance tripping problems.
A logical and methodical approach to fault finding for nuisance tripping will often uncover the problem.
