I am connecting a new LED light to a newly installed ET4. I want to clean up the original pool light junction box/switch/outlet setup and instead plumb directly to the ET with a short 1/2" pipe extension from the copper pool light conduit. I will install the new outlet in the ET knockout. Both the light and outlet will have their own dedicated gfi breaker. Do I have to keep the old pool light junction box? Or can I do what I want to do, get rid of the clutter and wire the light cord directly in the panel?
Also, I would like to use copper pipe for the extension but is galvanized okay if thick wall copper is hard to find?
I'l try to post pictures so you can get see what I am doing.
