[QUOTE="Andy™, post: 422532, member: 2012"] at best, its a complete bodge. those non-contact voltage detectors can be useful to give an indication something is live (and i do own one), however it is useless for testing dead and can easily give false reasings resulting in your death. for safe isolation you need a proper device, like a fluke T140 (probably different model by now, mine is a good few years old) or similar, and enough knowledge to be able to use it correctly & safely. from your posts, you do not even know the basics. for a start, you dont check for 'resistance to earth and earth continuity' . and putting a blue lead to earth and brown to N does not prove polarity either if this really is your training, then your employer is in breach of EAWR, and you are at a very serious risk of electrocution if you keep going the way you are [/QUOTE]
