    Potential relays are the small motor starting relays. Is that what you are
    referring to?
    If so drop out would be when the motor can disconnect the start winding.

    I don't really understand the process that is going on in the tank other than emptying so that you need to sync product input and output?

    But if the problem is that you don't have a large...

    The second worse shock I ever received in my 40 years in the trade was from a neutral.

    I was in a junction box that fed around 10 4 tube 277 volt lay in florescent lights.

    I was getting ready...

    Thanks that backs my thought of this being a hard thing for the engineers address anyway.

    I an't smart enough to be a nerd. :)

    That's the way I see it to, but with the extra ct.they are measuring each leg twice.
    I 'm not a math person but could you correct that by dividing your KW by 1.73 probably not because your also...

    The reason I said three phase was debatable was because if you have a neutral you might
    need three? :)

    I think a simpler way of looking at why you don't need to monitor the neutral with a CT.
    is that any current that flows through the neutral has to has to flow in either line #1 or
    line #2 and has...

    I am retired, but Yes if I did install one it would have 2 legs or lines and a neutral. :)

    Well since you did quote my post " uh B?

    As for the phase leg used on single Phase I Have learned to ignore it.

    Thanks:Ronald

    Wait just a minute when you said sustain I thought you meant the circuit could stand a arc better than a 120 volt circuit.

    Then we are in agreement you are saying the 240 volts would do more...

    This is like comparing apples to oranges. In manufactured appliances and equipment if designed for a higher voltage it will pull less current than one designed for a lower voltage.

    No had nothing to do with the size or voltage of the heater. I was merly stating at double the voltage at 240
    volts as apposed to 120 volts the arc in the loose connection on the knob and tube...

    That old myth is mainly from the way a dual voltage motor works by paralling the windings for a lower voltage or putting them inseries for a higher voltage.

    Nothing to be upset about.

    We all do...

    Thanks, I am too guilty of saying something like that because I don't take the time to think
    them out is the reason I did not say much more.

    I said loose connection and I meant a arc fault. And current across a resistive load such as an electric heater
    doubles when you double the voltage.

    I did not say the EMF would be fire hazard,...

    When I first read this post, like a lot on here I was in favor of it.

    After more thought I changed my mind.

    What if some one in a older house with knob and tube wiring
    had a 240 volt 20 amp....

    I see something in this that makes no sense to me.

    The transformer is suppose to be 120/240 to 120/240.

    Ok' we can't drive the two 120 volt windings in parallel with 240
    volts Right?

    What...

    This is not a uncommon thing on services with a high voltage drop on their feeder.

    I understand your concern for safety. Like you said it could be a loose or open neutral.

    If its not going back on the utility neutral and on the ground that leaves nothing but a open neutral.
