    VFD for powering a car lift

    Simply put, the convertor is not optimized for the load. A wiring diagram for the convertor would be helpful. You will have the same voltage imbalance when powering the VFD with the convertor. Rotary convertors are optimized for a specific load. Capacitors are chosen to balance voltages and...

    VFD for powering a car lift

    VFDs can be configured to be powered with single phase. Seems a bit silly to run a VFD off of a rotary phase convertor. The VFD will have a tendency to do the same thing that you are seeing now and that is one phase voltage sagging. - How is your current rotary convertor set up? Do you have...

    Share Animal Pictures: For Animal Lovers

    I trained a dog to give it up by threatening no more play. Jack soon learned what "Give it up or no play" meant. He also learned what "Can't reach it" meant if he didn't bring it to me or right to my hand. If he was particularly stubborn on a certain day, I'd hold my ground and ignore him...

    Achievable accuracy of thermostatic radiator valves

    I think the fact that it rotates makes it more likely that it could be IR. Otherwise a window or external wall would throw a false low temperature. But rotating would average things. It would even know when it's pointing at the radiator. By this it may be able to form an 'image' of the room...

    Achievable accuracy of thermostatic radiator valves

    I've followed this thread a tiny bit thinking this is impossible. But it occurred to me that one of the sensors could be an infrared sensor similar to the little hand held jobs that shoot a laser spot at whatever it is that you want to know the temperature of? This way the sensor knows the water...

    Storage mechanism with locking and unlocking

    Unless I missed something the discussion so far has been about a mechanism that after the rod is pushed so far, holds the spring and releases the rod from the spring. At this point the rod is free. What is it that returns the rod? Or is this a one time operation? You say you have no possibility...

    Series motors, switched to parallel

    This isn't quite right. If you mean a series wound motor by cereal motor, then by wiring two in series you will halve the voltage with equal loads. I would assume you will have a race condition upon startup. One motor will accelerate quicker than the other. The slow motor may never come up to...

    Random Photos

    @Andy Resnick Your pic reminds me of a younger version of my dog. We had to say goodbye in October. Losing a dog is tough to get through.

    A few questions about RCD

    Ok what you refer to as case #2 has the conduit/protective earth conductor/chassis tied to neutral, but no electrode driven into the ground. It will trip as drawn.

    A few questions about RCD

    Which is case #2? Specifics please. - I will again state that the scenarios in the links you have provided so far do not relate to the diagram you posted in the first post of this thread well enough to provide an intelligent answer. You are expecting the same yes or no answer for different...

    A few questions about RCD

    Ok so this is just more regurgitation of your previous thread. Are you Elizabeth in the stack exchange thread? It seems Elizabeth has the same tendencies that you do by asking the same question over again and in separate threads. This image and variations of it continue to pop up here on PF as...

    A few questions about RCD

    I did not say that. I said I will not continue to chase endless links that you provide in an attempt to support your incorrect position. If I didn't comment on other opinions then why would I have posted on your opinions? If you post the link to stack exchange I will look.

    A few questions about RCD

    Causing an internal bypass inside the RCD is how they are tested. Pushing the test button does something similar to what you describe.

    After all the other discussion in the other thread(s), how could you not realize this?
