Number of junction boxes per run

There's no limit.

This is not a consideration. Copper oxide is an excellent electrical conductor; aluminum oxide is not, but aluminum wire isn't allowed for branch circuits any more.

No limit to amount of junction boxes, just the total wattage of a 20 amp circuit

My jurisdiction limits the number of "devices" per circuit to 10. Better check your local laws as your's may vary. Cheers, cc

but a junction is not a device.

If there are lots of junction boxes the inspector may not feel that the job was done in a workmanlike manner. A circuit rarely has even one junction box, other than the ones the devices are in.

KISS.

I'd rather use a nice, roomy 1900 box for hooking up branches than an outlet box. Easier to cram wire nuts into, plus I've already got them.

They have to remain accessible, remember.

If there's a reason for a junction, any box of ample volume by code is adequate; I see no reason to think why there would be an inspection problem--again, assuming reasonable circuit routing and so on...

Now would be a good time to add a switch. You can switch the plug- ins :) to all operate from the switch.

Or several switches. Not always necessary to have all of the lights in the same room turned on.
