Hello, I have a source wire directly from a breaker to a switch and a light. I need to "splice into the source prior to the switch to add a switch and a recepticle.

I know I need a junction box. Do I connect all blacks and whites and grounds together, then add the switch, light and the receptacle?

There is currently 14-2 source controlling a switch and a light.

Thank you

 

Yes that is correct provided you are certain that it is before the original switch.

 

There's not enough detail in your post to know if you have it correct, but at least I see nothing obviously incorrect.

 

There is a source wire from the breaker box...connected to a switch and a light. I want to add a junction box, prior to the switch to add another switch and another light. The junction box will have the source wire, the wire to the existing switch and the new wire to the new switch. I will connect all like wires in this box together, then wire accordingly at the new switch and light...if im wrong,,,appreciate feedback, Bob

 

And then you have another cable from the new switch box to the new switched receptacle, right?

This all looks okay. One potential problem is getting enough slack in the existing cable to make proper connections in your new junction box. You should consider replacing the segment of wire from the junction box to the new switch, or to the panel, in order to ensure that you have plenty of slack. There should be at least 6" of wire from each cable inside the box.

The junction box must remain permanently accessible.

An alternative design is simply to skip the junction box and run a cable from the old switch to the new switch. If the switch boxes are not too far apart, this is a superior solution.

 

Thats a good idea...what are the connections at the first switch...im assuming pigtails are involved and such...thanks alot, bob

 

At the existing switch, simply connect your new cable white to the other white wires. Connect your new cable bare to the other bare wires (which should already have a pigtail to the switch's green screw).

Now figure out which of the cables coming into the existing switch box is the power cable. Take that black wire off of the switch, connect it to the black wire of your new cable, and pigtail it back to the screw you took it off of.

 

Thanks alot, ill reply when done...probably tomorrow...Bob


...works great...my son is happy. His room is in the basement. It was wide open. He had no wall and door. So, I added a wall, door, separate switch, 2 lights , receptacle...all works like a charm...thanks for the help, bob
