RE: wiring two switched device on one GFCI circuit.I presently have one 20 amp circuit dedicated to only a switched swimming pool light. The GFCI is in the attached outlet. I want to add a mister pump for the patio and control it from a wall switch (not the switch built into the pump box). Can I put two different switched devices branched from one GFCI outlet so the outlet is always hot and the two switches operate independently. If so, a diagram would help.
Already Tried: Too much trial and error! My 'logic' doesn't work. (Yes, I am diligent about safety.)
Let me see if I have this clear, you have one Outlet now, and from that it goes to a Switch for a pool pump? from that you want to add another switch?
Yes. Also I assume the new pump for the mister cooling system should be gfci
Anything outside should be gfci protected. Now are you planning on having both switches in the same location?
Yes, both switches can be in the same box.
Ok in this case the wiring will be simple. Take the black wire coming from the outlet (which is also attached to the current switch) and connect that to the new switches bottom gold terminal. Then take the black wire going out to your new pump and connect that to the top gold terminal on the switch. The white wire from the new pump will connect to all the white wires in the box. Same with the grounding wire. Does this make sense?
It sounds simple and I've been making it hard. Clarification:
The black wire coming from the Panel goes into the outlet at the ?? Line ?? and out at ?? Load ??, then to the first switch as you described.
Right, the wiring from the panel both black and white goes to the gfci's line side. Everything else will be fed from the load side of the gfci.

Cool.
Black from panel to Line outlet, then 2 wires out (one for each switch) then each on to devices.
Whites go from both devices and Line of outlet back to panel. Thank you.
Actually only the white wire from the panel goes to the line, and the black from the panel go to the line. Everything else will be fed from the load side.
Yes I got that thanks. I'm doing something wrong because switch A controls device A OK but device B requires both switches to be on.
That just means that you did not run the incoming power to both switches. You need to run power to the bottom terminal of both switches.
Everything works now, thank you. We're sitting on a cool patio with mister working in 100 degree Phoenix.
Good deal. If you should ever need anything further, please be sure to let me know. Have a great day.
