multible junction boxes?

hello all, first post here, hope you can help me out!

can you have more than one junction box on one circuit?
I want to mount them in an unfinished attic, I am trying to update from a knob and tube no ground 100+ year old house.
I just do not like so many wires held together by a wire nut!
I want to use more than one junction box on a circuit because I would have too many wires in just one junction box, plus it would save me some length of wire to do it this way. and before someone ask, I have figured the total circuit load and it is well below my wire size and breaker capacity.

Yes you can have more then one junction box
But better to use as few junction points as possible & use a larger box & the right size wire nuts

Technically speaking, every outlet, switch, and light fixture is a junction box, so yes. As suggested above, fewer connection mean less potential for connection problems.

Sometimes a cable gets cut and the ends don't reach so you need two junction boxes with an extra short length of cable in between.

If you have too many wires that want to go into one wire nut you can split them up into two (or three) bundles with short lenghts of wire (pigtails) to connect the bundles.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
