We had a guy in to do some drywall repair. He showed up before I got home and removed a ceiling light fixture, and I have to infer what's going on in there to replace. Hanging into the box there is a bundle of three white wires which I presume in the neutral. There's a bundle of black wires that is tucked up into the top of the box. There's also a red wire hanging down that I presume is a switchable live wire. I'll test when I get home, but is there any other likely configuration?
