For drawing simplicity, I had the third wire come out the other side, but it really of course comes out the same side the other two go in. Also, please ignore the coffee stains. They have no electrical significance . On the old thermostat, lines A and B were tied to “line” screws, where as line C and D were tied to “load” screws. It's wired for a landline, but we've never used it. Previous owners must have had 3 business phones lines to the house. There is a junction box for those landlines on a finished basement wall. I would like to reclaim that wall real estate and disconnect the wiring from the box and remove the box and drywall over the opening (2" by 2"). It looks as if a direct feed from the power panel comes to this box and then feeds out to two other branches. The fourth black hot wire appears to feed toward the fan wall switch (exiting the box at the top right). The switch switches that hot line and sends the switched power back to this box on the white wire (part of the top right bundle). I'm replacing lines (again) on my 2000 3500 4WD, Ext. Cab, Long bed, and this time the junction box at the front of the truck that the front-to-read hard line threads into, pulled the threads with the new line 1/2 way threaded in.
If the WHOLE circuit (not just the parts you have altered) is 12Ga you could consider going to a 20A breaker. If there is ANY 14Ga it must remain 15A, and your box fill would be easier to manage if your new wires were also 14Ga (2.0 cubic inches for each 14Ga wire "count" .vs. 2.25 cubic inches for each 12Ga wire "count") - it adds up. It’s perfect for smaller connections and typically has a depth of around 1.5 to 3.5 inches. 2 Gang, 3 Gang, and 4 Gang Boxes: Need more space? These larger variants of standard junction boxes are your best bet. You can either group a bunch of standard boxes together or opt for a 2, 3, or 4 gang box.
Lighting, Light Fixtures, Ceiling and Exhaust Fans - Can I branch out multiple wires from a junction box? - Can I have one main power source where I connect 2 other branches to separate circuits. All inside a junction box. In other words, 1 source turns into 2. I believe I would just connect live to live, neutral to
Overfilling a junction box with too many wires may lead to several issues such as overheating, electrical fires, short circuits, etc. That is why it is so important to follow the box fill capacity of each junction box properly. Problems Caused by an Overfilled Junction Box: With more wires, there is more electricity passing through the junction .This is the close-up The conduit in question is in the center of the photo. hello trustworthy Electricians I have a new question about the way conduit should go into a junction box. In the bigger picture of much if the wall, you can see a small, flexible metal conduit going into a junction box (there is a single plug with a black cord plugged into the center of this junction box).Ok, using your meter set to ohms, and everything disconnected in that junction box, find out which cables go directly to switches and follow the others through the attic to see where they go. Electrician: Sam I. . My basic problem is stupidity. I have three switch cable lines going into the box. How do I activate each of the switched circuits .
A typical "deep", new-work box is 22ci. If you are using 12/2 Romex and putting an outlet in the box, the required size is: 6 conductors coming into the box: 6 * 2.25 = 13.5ci; Your outlet counts as 2 conductors: 2 * 2.25 = 4.5ci; The ground wires count as one: 1 * 2.25 = 2.25ci; Required size: 20.25ci; So, you should be fine. Looking for a way to connect 3 sets of #6 in a junction box. Swim Spa calls for the wire to come from the disconnect into a junction box and then into the 2 pumps. I was thinking these Polaris multitap connectors would be the best solution but open to all suggestions! Also I originally thought a 6x6 box would be ok but maybe 8x8?
I took out a light fixture in the basement with the intent of installing a new one which ive done before and I come across 3 sets of wires (3 black, 3 white, and 3 ground wires) i didn’t take a pic or mental note of how it was wired to the old fixture and now I’m confused. Every time I turn the switch on the breaker trips I assumed that if the hot wires going into the outlet are reading the same low voltage as the outlet, the outlet must be ok, so I thought maybe a junction box existed between the breaker panel and the outlet in which .

I'm trying to figure out if I can split a single branch circuit into two runs. Basically, I want to add an outlet to a circuit, but it's not in a convenient place to put it in line with a single run. The wiring would look something like: Therefore I'm going to have to extend the other two by using a junction box as I cannot trace them back without taking up a stack of floorboards and I do need to get this done pretty quickly. Also I have found that it is a complete nightmare trying to get the wires back into the socket and much swearing has been heard when trying to attempt this! So one outlet has three 12/2 cables coming in, two of which go to the other outlets. . a GFCI outlet takes a lot of space, and can physically "cube out" smaller boxes. On the other hand, larger deeper boxes, such as a 4x4" with a 1-gang mud ring or any of the new-work in-wall boxes metal or plastic, won't have any trouble at all, and this .Customer: why would we need 2 circuits going into the same junction box?

Are you referring to a specific appliance or electrical device that requires two circuits? .
I am curious about my options with 2 breakers running into one box and your guys thoughts on which option may be best. . Both lines concluded in this box, so there's nothing 'downstream' that this should be interrupting. . (if done correctly, a MWBC will be in a single /3 wire instead of two separate /2 wires), as the breakers will need to . Mixing circuits from 2 panels into one junction box. . it's going to be bonding 277 and 120, definitely a no-go. In the fine print, the note at the bottom of page 3, it says both pole's line connection must be the same phase, which should be enough to settle the argument. edit: I am not sure how they could be on different circuits on the same . I envision one feed line for 2M and the higher bands. I already have a splitter so one feed line should be plenty. Rather than erect a tower I plan to use dipoles for a few of the popular HF bands. I'm thinking one feed line from the junction box into the shack connected to a multiplexer switch in the junction box.
I was going to add on a receptacle downstairs that piggybacks off of the power to the switch. Currently the wires in the junction box are lines 1 & 2 blacks connect to main line. Line 1,2 &3's whts are connected together and lines 2wht and line 3 black are connected. This does not work to send proper power to my switch. A breaker box is a perfectly legitimate junction box. Assuming (since you mentioned moving the cable to the breaker) that you have adequate slack in the cables to move them to the breaker box:There is a black, a white and a red wire in the junction box. The old fixture was connected to the white and red wires only. This led me to believe that something is not normal, because i expected it to be connected to the white and black wires at least and i though the red wire was the ground and could have been neglected by the person who . You can't bury the junction box. Obviously the temptation is to seal up the steel box and bury it behind trim or whatever. Can't do it, not allowed. The junction box cover must be accessible without the use of any tools. (other than the two screws holding on the box cover itself, obviously). However, you can make the junction box be dual .
After receiving a fun little shock, I found that someone was using 14/3 cabling to carry 2 different circuits to this 1 gang box (line on left, load on right). Since the load for Circuit 2 doesn't have a matching neutral, it's connected to Circuit 1's neutral line. And before you ask, Circuit 1 and 2 are not MWBC circuits.
