Electrical – add a junction box in the attic to ease congestion in a ceiling box

electricalfanslightingwiring

I have an existing ceiling junction box feeding a ceiling fan (with lights) that I'm replacing with a flush mount ceiling fan (no lights) and plan to add four recessed lights controlled by a separate switch. The ceiling junction box currently has four 14/2 cables in it. (One feeding power in, two taking power to ceiling junction boxes in adjacent rooms and one is the switch loop for the fan.)

I need to add a cable for another switch for the recessed lights so rather than cram a 5th cable in an already crowded box I was planning on installing an attic accessible junction box on the joist next to the existing box. I'd move all the connections to this box (Power in, two cables feeding other boxes, new cable to the fan/recessed light switches.)

Assuming I use appropriate boxes, connectors, grounding, etc., are there any obvious flaws / concerns with this approach?

Assuming your attic is accessible via a persistent access panel, that's fine. There's no difference between that and, say, having a light and switch up there. Just be sure to run the cables in such a way that they aren't prone to damage from foot traffic, and fasten (staple) to code (generally every four feet and within 12" of boxes).

That said, if your box is standard round and 2-1/8" deep you can have five cables coming in. You'd be at max with ten #14 wires, but with a little planning and careful laying-in it would fit.
