Basic lighting question.

[Sandersman]

I'm trying to figure out the wiring arrangement for some lighting (for college, not real life).

The circuit will be wired in singles in conduit. Am I allowed to split the live conductor into "branches" like I have in my, admittedly rather poor, diagram?

I need to run a permanent live to my emergency lighting, so I was planning on taking a live and splitting it to give a switched live and a permanent live (which will have a keyed switch to test emergency function). I'd also just run the permanent live around the installation as the feed, and make branches off where I need more switched live. Because the circuits we are designing have a maximum permitted length, if I'm not allowed to "split" them like this, will I just have to run separate circuits?

Sorry if the terminology is a bit wrong. Hopefully this makes sense.

Cheers

Hi and welcome!

With singles in conduit, where the lengths permit it is usually preferred to loop-in at fittings rather than place joints randomly around the system. So a permanent line would visit each point it is needed following the straightest route, accepting that there will be some doubling back required. Obviously if this drastically increases the length there can sometimes be justification for splitting it in a suitable joint box. For a study exercise, I would expect that the intended method is to loop-in line and neutral everywhere.
