In electrical drawing, how many PVC circular boxes needed if you have 6 ceiling lights?
it would be 6 obvioulsly a box for each of the light's connection and also to hang the light? No offense but that question doesn't really make sense?
It depends on what lights you are installing. If it like keyless fixtures you will 6 3/0 boxes.
Only three if the lights are going to be set up in two. 6 if they are going to be spread throughout the room, or one using the box as a J box and running flex tube to the light locations and it will also depend on what kind of ceiling. Some use drop, some use hatrack and gypsum.
Depends. One for each lighting point. Then how many switches are there? Are you branching off from any point (you'll need one for every split in the cables) or will you run from the first box through the rest to the last - then you don't need any extras for branching. Your question is not really specific enough.
