Wire goes where?


Hey guys.. Got a wiring issue. Power comes from panel, then to 5 lights then switch. Can't get it to work. Think I need a 14/3 wire in there some where. Any one got a diagram to steer me in the right direction?

Um, more information?

Unless you have a couple of three way switches, all you need is 14/2 w/G, so long as it's a 15 amp circuit. 12/2 w/G if it's 20 amp.

Black is power, black into and out of switch, then to the lights. Black and white to all the lights, in parallel.

To switch it last, you'll have to wire things in series, white all the way through solid, black in and out of the lights. You do NOT want that. Remember christmas tree lights where one blew and all of them went out? That's series.

Yeah i dont want a series. If I ran a 2 wire from panel to first light. 3 wire from light to light and 2 wire from last light to switch. Black from panel all the way to switch..red from first light to switch. White from last light back to panel. Looks right on paper but going to have to try it to see if it works. Not ready to call the pros in yet...or maybe change it to switch first...

I figure if you have just 1 switch, you have to go through the switch first or the lights have power all the time

To do it right, you will need two types of jacketed cable, 14/2 w-ground, and 14/3 w-ground Romex or similar brand; get enough to do the job; I know it is expensive, but coming up short is a real waste of money. You will also need a small roll of RED electrical or marking tape.

First, find the location of your source for the additional lights, and turn off the circuit breaker to the circuit.  Use a test light or a meter and test the wires in the source box as being de-energized.  In that location, if it is an existing switch or outlet box, there should be at least one or more BLACK wires connected together, one or more WHITE wires connected together, and one or more GROUND wires connected together. these will be the wires where you will tie in the addition.  If the source is a circuit breaker in an existing panel, it must be a new addition to the panel; you cannot connect an addition to an existing circuit at the breaker - only one wire is allowed in a circuit breaker.

Next, run a piece of 14/2 w grd from the source location to the first light outlet; then run 14/3 w grd between the five light outlets; then another 14/2 w grd  from the last light outlet to the switch box.

Next, go to the box for the switch and strip the outer jacket from the Romex, and using the red tape, mark the WHITE wire red, either the whole exposed length, or just at the end.  Now, you will have one BLACK wire, and one RED wire in THIS BOX ONLY, plus the ground wire.

Now, go back to the last light outlet box where the 14/2 goes to the switch box, and mark the white wire from the switch box RED  the same as you did in the switch box.  So now, in that last light outlet box, you will have TWO GROUNDS, TWO BLACK WIRES, TWO RED WIRES, AND ONE WHITE WIRE which comes from the next light outlet box.

Then, go through ALL of the boxes and tie ALL of the grounds (either bare copper, or green insulated wire) AND the grounds on the fixtures you are installing together in each box; unless the fixtures are heavier than a couple of pounds, they will just hang there on the ground connection just fine.

Next, go through ALL of the boxes and tie ALL of the BLACK 14 wires in the Romex (the 14/2 AND 14/3) together in each box - DO NOT connect the black wires from the fixtures to the BLACK wires in the Romex.

Next, go back to the first light outlet box and tie the WHITE wires AND the WHITE WIRE FROM THE FIXTURE together in each box.  In the LAST light outlet box there will only be two white wires to tie together, the one from the fixture, and the one from the previous light outlet box.

Next, go through each light outlet box and tie the RED wires in each box, AND the BLACK wire from each fixture together.  In the first light outlet box you will only have one RED wire, and one BLACK wire from the fixture to tie together.

Now, go back and check all of your work for accuracy and security - make sure the connections are sound and nothing will pull out of a wire nut; then mount the fixtures to their boxes.

Next, install the switch; connect the RED wire to the lower screw, and the BLACK wire to the upper screw, and fit the switch into the box and install the cover.

Now, go to the source location, and tie the BLACK wire into the existing BLACK wires, the WHITE wire into the existing WHITE wires, and the GROUND wire into the existing GROUND wires.  If you are coming out of a panel, connect the WHITE wire to the NEUTRAL bus bar, and the GROUND wire to the GROUND bus bar, then install the circuit breaker, making sure the toggle is in the off position, and connect the black wire to the circuit breaker.

Turn the breaker, either the new one, or the one that feeds the source location on, and check to see that your new lights work.

I will see if I can come up with a suitable illustration for this, but if you follow what I have written, you should be alright.

Sure a lot simpler, and a lot less wire needed, if the switch is gone through first, then to all the lights. 14/2 w-g all the way. But then, I am simple.

Got it...Rrumbler had it right. Yes it would have been easier through the switch first but would have to run 53 ft of wire to get to the switch then back through the lights, then to the panel..Thax for the help.
