Electrical Testing

This area has subsections on electrical installation testing, testing of fixed appliances such as immersion heaters, various types of test equipment and how to use it. As with the other electrical sections, this is intended for the UK, although procedures in many other countries will be similar.


Fixed Equipment - Electrical testing of fixed equipment such as immersion heaters
Installation Testing - Installation testing for electrical circuits in UK installations
Test Equipment - Various types of electrical test equipment and how it is used
