I'm looking at retrofitting fluorescent fixtures in my basement for single-ended LED tubes. The electrical and wiring concepts I have down; I could probably do it with my eyes closed (but anyone working on line voltage circuits with their eyes closed is an imbecile that deserves what's coming).
What I don't get is that all the instructions have you cut all the wires right at the ballast (makes sense, so you have longer wires to work with)... but then many of them go on to explicitly state to leave the now-useless ballast in place! It'd make sense if they had you cut maybe 4-6 inches from the ballast, so it could be wired back in in the future if desired, but with nothing but wire stubs it seems to me the ballast is a useless brick in the fixture. Is there some code/safety/etc reason I'm not seeing that mandates keeping a paperweight in your fixture? Or is it okay to just uninstall it entirely and send off to e-waste?
For reference, I'm in the US (in case it's an NEC/NFPA/whatever code requirement). If it's due to a code requirement, insight into the logic behind said code would be appreciated too. I know most codes, even the arcane, archaic, and convoluted ones, have (or at one time had) a basis in personal or fire safety, so I'm curious.!
EDIT: I've added a picture of my fixture... It looks like there was an old ballast in there, possibly magnetic, and they did the same thing: cut it out electrically but leave it mounted. I'd be quite happy to remove both.
