junction boxes
 
I have a 20 amp outlet w 12 gauge for outlets and wanted to know if there is a limit to how many junctions I can have on the circuit .I have it coming in to one room juctioned there,then going to another and juctioned to go in both directions in room like a Y .
.it ends there.
Is there any limit to these per circuit and do these effect furthest outlet at all?
Any info is appreciated.

Depends on what they're used for. Kitchens, Dining Rooms, and Baths have special requirements, but other than that, no limit that I know of as long as the breaker is 20a and the wire is #12.

What are they used for?

Bedroom outlets.

Should be fine, but why #12 and 20amp? Your choice, but I like #14 and 15a breakers.

You didn't post your location so I will give the answer for CANADA.
I Canada you can as many junction boxes as you like as long as they remain accessible. They can not be buried under drywall.
You can only have 12 outlets on a circuit. Junction boxes and switches do not count as outlets.

You need to go back and add your location to your profile if you want to ask code questions.
Just got to Quick links to edit.

I already have a plenty of 12/2 and will be running seperate 20 amp circuits in other locations ,dedicated,so I have plenty of 12,the circuit I'm coming off of has 12/2 20 amp. I don't care to downsize to 15.I'm in Tn(as for code).
Thanks for info.

if you are adding circuits ... 13 for 20 amp

220.14(I)

There is no limit to the number of junction boxes on any given circuit. But realize that every JB is another potential problem. We professionals very rarely use JB when installing new cabling. Also, there is no limit to the number of receptacles installed on a circuit in a dwelling unit.

This does not apply to residental. You could have 200 receptacles on the circuit.

220.14 Other Loads All Occupancies. In all occupancies, the minimum load for each outlet for general-use receptacles and outlets not used for general illumination shall not be less than that calculated in 220.14(A) through (L), the loads shown being based on nominal branch-circuit voltages.



I assumed junction box here in this thread to mean outlets ..LOL

I stated "if you are adding circuits" .. so they would not have been in the original load calulations ...
