    Solution needed!!!!…I used a Contactor instead of an ATS to connect 2 power sources (main and ups) for power redundancy

    I used a Contactor instead of an ATS to connect 2 power sources (main and ups) for power redundancy and the output is connect to a Dell server. i.e, if main power is lost contactor will changeover to ups power and there should be continuous power supply for the dell server… but i have a...

    Switch mode power supplies and protection class.

    My understanding is that a SMPS does not separate, like a SELV transformer, the secondary from the primary. Therefore presumably the equipment supplied cannot be IEC protection class III. So what class is the equipment? For example a laptop with an SMPS, metal body and high resistance...

    Lutron Caseta dimmer won't power

    A few days ago we had a brownout and an existing Caseta switch started smelling burnt and its lights wouldn't turn on so I figured it needed replacing. I purchased the exact same model ( PD-6WCL-WH-R-C ) and installed it just as the old one. However, the ceiling lights don't come on and neither...

    I happened on this web site today that shows the UK power production & demand: https://grid.iamkate.com/ The obvious elephant in the room is today just over half of the power is from gas. What is missing to me is an indication of percentage capacity, i.e. how much of each source is being used...

    Can I tighten neutral circuit breaker wires without turning off power?

    I have some lights flickering in the house. I was told tightening the circuit breaker wires in the electrical boxes might help eliminate the flickering. Is it possible to tighten the wires without having to turn off power to the house. Thanks
