    Start up sequence of single phase Copeland compressors operating on 410a gas



    How does a single phase 230V Refrigeration compressor start, it has a 60-micro fad run capacitor? I assume on start-up there is a supply going to the Run and Start windings, as the compressor reaches running speed the power reduces and will only flow through the run windings, and there will be no power going through start windings as start windings have a larger resistance.
    Would like to know if I am describing the sequence correctly. Also, where can I find the resistances for Copeland scroll single phase compressors operating on 410a gas.

    Best regards,

    Both the run and start winding have current flowing through them during starting and running.
    Mostly found in Oxfordshire, UK :)
