Can two separate circuits be in the same junction box. He is saying the associated with those circuit conductors only refers to each individual circuit not all the separate circuits in the same box. The porch circuits are already present but i dont think these would pass current code. Both circuits are properly grounded at the sub panel. If 2 of the circuits are on a mwbc 143 cable then you would just need to keep the 2 neutrals separate. I have a ceiling fan all wired correctly. All the ground wires count as 1x of the largest ground in the box.
That is two cables enter from different breakers and they tie to cables exiting but the two circuits arent connected except for the grounds if that is required.

He could not give me the code. 2 electrician told me i can run 123 for dishwasher and food disposer and have one receptacle under the sink with upper and bottom connected on different dedicated circuits but from one 123 cable. Based on the nec the wire fill would be calculated at 20 for each conductor for 14 gauge wire and 225 for 12 gauge wire. They have two separate breakers and use 14 2 wire to the current double gang box.
I will have a four gang box near door room light light outside door and two separate covered porch circuits. I know nec puts significant restrictions on having different circuits suppling outlets in same box but i havent found any mention of doing this with switch boxes. When neutral wires of two or more separate circuits are connected at other than the main panel the electicity has multiple return paths resulting in net currents. Can more than one circuit be run through a single junction box. Just seems strange to have two separate breakered circuits in the same wall junction box.

Assuming the junction box has the proper capacity i want to run a separate circuit through that box so as to split off a circuit which will then go two different ways to power up an outlet on one wall and two other outlets on a different wall. The answer is yes you can have 2 separate circuits in the same box they can have a splice also but not needed in your case. The device or switch counts as 2x for the largest wire connected to it or each in the box. The only concern would be the total box fill. I had to go back to the breaker box to find the breaker for the second circuit and shut that one off as well. Can two different circuits go through the same junction box.
Well lets put it this way how would you extend the circuits to a distribution board if it needed to be moved 2 ft away from its current position and none of the existing cabling would reach. Jdevlin 178061 052208 0151 pm. Junction box wiring electrical question. I think there is just 14 3 leaving the box to. As the title states. Ground wires from different circuits in same box re.
Not the breaker box but rather the junction box seems dangerous.
