    Switching a gfci receptacle??

    I'm not sure at the moment and looking for confirmation please..
    The new gfci receptacles, when power is applied the first time they trip and need to be reset.
    I'm would like to switch a couple gfci receptacles but not if they are going to trip every time I turn them off and then back on..

    Do they only trip the FIRST time they are energized or every time they are energized??
    I'm thinking only the FIRST time, but I'm not sure...

    Thank you

    Please let me also ask,
    I'm planning on switching the gfci receptacles supplying low voltage landscape transformers. If the gfci receptacles ONLY TRIP at FIRST energizing, would there be any issues of possibly tripping the gfci when the transformer inductive load is energized?

    Thank you

    If you want to GFCI protect the receptacles supplying your outdoor lighting transformers, I would do one of 2 things; use a GFCI breaker or use the feedthru from a conveniently mounted GFCI receptacle.

    Good ideas! GFCI ahead of switch.

    Thank you,

    My thought was power in > timer > load timer > dead front inside > exterior duplex receptacle

    (was also thinking a installing a single pole switch either after load timer before dead front or after dead front before duplex receptacle as a Master OFF )

    Was thinking timer before gfci... are you saying,

    power in > dead front > timer > load timer > exterior duplex receptacle (and master toggle off between load timer and external duplex receptacle) is a better design ???

    thanks again

    From my use I don't see that the new GFCI trip on a power off situation. If that were the case one would need to reset all the GFCI in a house after a power failure. That is generally no the case.

    I have many GFCI receptacles for landscape lighting switched via time clocks. No problems.

    ritelec:

    Why don't you run an experiment? Why did you not experiment before asking the question? What is the specific manufacturer and part number you are referring to as "new" that supposedly has this characteristic?

    Logically why would you expect that a receptacle be designed such that it had to be reset after any power loss? In a low cost product do you expect that a one time memory can be included that will detect the first ever time power is applied?

    I believe what has been done is to design the GFCI so that when shipped it is in the tripped state, and in this state that, if it is wired backwards, input to the output terminals, then it can not be reset because reset is also an electrical function, no power to do a reset, and not just mechanical.

    Do some experiments and see how the GFCI works. Open one up and study its circuit and mechanical operation.

    I was laying out and planning to switch 3 transformers via photo cell, time clock, and master off switch contoll for each Gfci to the 3 transformers. The thought to do a Honeywell 7 day timer rated for inductive loads as the photo cell isnt rated for inductive and the time clock would need to be reset for daylight savings.
    Laying out the wiring and materials needed I questioned if the Gfci would trip and googleing showed sometimes it did. Was hoping I could go in and install and turn things on without having to experiment
    Headed to supply house and will pick up Honeywell or photo cell and time clock depending on how the spirit moves me. I will install timer ahead of Gfci as to not lose memory in the electronic timer or mechanical clock and leave room for moving things around in the chain if there's issues. Thank you and have a great weekend

    Edit.
    Will do Gfci protection first as that was suggested and also when those transformers are installed they are set up for Gfci power in then photo cell and timer options in transformer secondly.

    Thank you.
