    3 phase contactor advice

    Cheers for the replies. The method above is exactly what I'm trying to achieve. The Time Clock is switching the coil perfectly bringing it on and off But the manual stay button will not hold the coil in and the stop button will not break the contact The schematics provided by schneider have...

    induced voltage

    Tested with a megger 1730 The issue came about when I was about to carry out an insulation resistance test. The test couldn't be carried out as the test leads where picking up a voltage. Once all rcbo's where switched off each circuit tested clear > 999 Had heard of induced voltage was the...

    induced voltage

    How do I get rid of them! Testing a job another contractor has been working on. In the main hall of the building there is a switch bank of 7 switches and 7 emergency key switches. Each of the switches are on a separate circuit. When I remove one of the lighting circuits from the rcbo I get 80v...
