    Hi

    Yesterday, I cam across this mechanical time switch (Intermatic model T104) and then googled it and couldn't understand its connections so I thought that I should request you for help.

    Please have a look here. Thank you.

    Q1:
    What do "24 FLA" and "28 FLA" mean?

    Q2:
    Does this mean that the clock motor should be supplied with voltage between 208V to 277V with frequency 60 Hz?

    Q3:
    I don't see how connections need to be made.

    i: What does that dashed line running from motor to terminal 1 stand for?

    ii: What do those two arrows mean?

    iii: What does that statement in pint highlight mean? I know that it's saying that if you have 277/480V connection then you should use terminals "A" and "1". Also check Q2 above.

    Q4:
    What do these numbers mean?

    Q5:
    I had thought that such a switch isn't used any longer but from Amazon reviews it looks like that such switches are still quite popular.

    Regards
    PG
