Combining Old Wire To New

Hi, I have a fluorescent light I'd like to remove and add a tracklight.



Luckily it's in the basement with an unfinished ceiling.



here's the circuit map as is now:



1. breaker to fluorescent light.... connections inside

2. fluorescent light to switch at the top of the stairs

3. switch to the light in the stairwell. This terminates the circuit.



The wiring is all 14/2



I'd like to replace the the fluorescent light with a track light, but I'm not sure how to continue the circuit to the switch in the stairwell.



Is it safe to...



1. bring the cable from the breaker to the junction box.

2. connect the black wire with the black wire on the light AND the black wire leaving the box to the switch in the stairwell using a marette.

3. connect the white wire with the white wire on the light AND the white wire leaving the box to the switch in the stairwell using a marette

4. connecting a 6 inch bare 14 gauge wire to the box ground screw, then using a marette, connecting it with the ground wire from the cable entering the box as well as the one leaving and also the ground wire from the light.



Will this work and is it safe?
      

Hi, I recently moved into a 1954 house with a  20amp electrical system, not the old fuse type, but there are no ground wires.



I removed an old light and replaced it with a light fan combo. As I removed the old light (after turning off the breaker) I noticed from the ceiling that there were 2 white wires tied together with a wire nut and 2 black wires, one attached to the white wire in the light and the other attached to the black one from the light. Feeling this was wrong and should be black to black, white to white, (even knowing full well the light was working fine before I disconnected it) I wired the fan the way I've always wired fan lights,  white to white, blue and black to black.  (again, knowing full well the light was working the other way). Turned breaker on then powered on switch. POP at the switch, breaker switched off. I reworked it back to the way it was before with whites tied off, black to white, black and blue to black, turned it back on and  viola, things worked fine. (I know, duh... Right???)

2 questions from this experience...

1. Why would the 2 whites be tied off with only black wires used?

And 2. It seems that one of the light switches in the same circuit as the blown one is now working soft. In other words, it used to make the normal click noise when turned on/off but now it just moves softly up and down without the click. Could I have damaged something when I mis-wired?
      

I have new 12/2 wire running to my attic (home built 1920) on a 20amp breaker.  My service is 100A and the box is older but not ancient.  The only thing on the line is a couple of outlets and 2 lights.  Would it be code to switch this breaker out for a tandem 15amp breaker?  This would open some space for me as my box is full.  Thanks.
      

I am working on fixing an issue with the wiring in one of the bedrooms in my older mountain home. Though I was not present for the cause of the problem, here is what was told to me by the tennant.  he claimed that he went to turn on the light in the closet, (a 3 lamp track bar light, wired to a switch) he heard a loud pop from the light in the closet and lost power to to the room. The room has 6 recessed ceiling lights on 2 separate switches, presently only half of the lights work.There are no breakers tripped, no obvious shorts at outlets. I have opened the drywall following the wires around hoping to find a short but I have found nothing. I decided to try something, and I bridged the working switch to a dead outlet and everything turned on. I am waiting til the daytime to follow the wires outside to the breaker box, but so far no breaks or anything.. curious if anyone has any pointers.. could the pop he heard from the track lighting have killed a breaker? its about the only thing left.
      

I'm replacing my electric range with gas.  The electric has (I think) a four-wire #6 or #8 cable approx 60ft run with a 40a dual post breaker.  I say "I think" because the wire is behind everything else in the panel.  I see red/white/black wires, but no ground and I can't read the jacket.  Once I cut the main, i'll have a closer look. 



The gas range requires only a 15amp breaker. 

Can I simply replace the breaker with 15A and the 4 prong outlet with a Nema 5-15p?  I'd cap off both ends of the red wire.  Is there some sort of code that says I need to maintain the 40A circuit for a future stove?

Or is there some sort of transformer I can plug into the stove end and avoid all that hassel.  ?
      

Hello



I recently upgraded my old fuse panel with a circuit panel.  One of the circuits contains mostly lights and also my furnace.  The wire on the lights are 14/2 and the breaker is a 20 amp breaker.  Can I replace the 20 amp breaker with a 15 amp Breaker or do I need to change all the wire.



Help



Thanks
      

Older house with the metal enclosed wiring has stumped me.  I am attempting to add a second switch for a fan off existing light switch in bathroom.  Existing wiring:  W,B,R from panel, W,B to light.  2 white wire are tied together, two black wires to one contact and red to other contact on switch.  Disconnected all wires and confirmed the black is live from panel.  It seems to me the light is seeing power the entire time since the blacks are connected? I'm confused, please help. how do I add another switch onto this circuit?  Thanks!
      

I'm trying to fix a problem with a track light installment over the a bar I've just put in. I've done it before. never had issues. but this particular problem is driving me nuts. It just defies logic.  The electrician who actually installed the associated dimmer switches with this dining room area was called as it seems it may be a flaw with his wiring, but he's blown us off and I have to try and solve this myself.



This is how it's all set up. I've been rehabbing our home from top to bottom, and converted our old kitchen into a dining area. Within this dining area are four sets of lights, all controlled from one box containing four dimmer switches. I set up all the new wiring and installation of the lights in the ceiling, and we paid an electrician to come in, check everything out, set up the multiple switches, and connect it all to the board. It's all new copper wiring from beginning to end, as I didn't want to connect or splice in to the old aluminum wiring that was in place. All the new wiring and lights are on a dedicated 15 amp breaker. Three of the sets of lights were set up to be available from the day the electrician came around. The fourth, for the track light over the bar, was left hanging from the ceiling capped off and with the switch off, as I still had work to do installing an overhead wine rack, under which the track was going to be set.



Two days ago I finally got around to putting the track up, but after setting it in place and connecting the power up the lights wouldn't work. I took the lights out to our kitchen, where I installed another track light system some time ago, plugged one of the lights in, and it worked just fine. I then went back to the bar area and used a spare track, then a spare connector, to see if I could isolate the fault, yet neither of the items provided a solution. Now here's the weird bit - every time I tried checking the system out, I'd get 120 volts showing from the wiring and from the track when I'd test with the multimeter. But the second I'd put a light into the track, the multimeter would drop to zero on the voltage reading on either the wiring or the track. Take the light fixture back out, and the voltage would pop back up. Inserting the light was thus completing some kind of odd loop. It wasn't just one light - I double checked by grabbing working lights from the kitchen track and inserting them into the other track - the same problem would pop up. Finally, having come to the conclusion that there was nothing wrong with the track at all, I took the whole assembly over to a nearby wall outlet, used some spare electric cable to connect up to the appropriate slots - presto, the light came on! I even double checked all this by grabbing another light fixture destined for our bathroom, and tried connecting it to the wiring over the bar. Nothing. Yet as with the track light, the minute I took it over to the wall outlet and connected it, the light worked.



So everything logically points to the fact it has to be something to do with this individual circuit, right, because a) the light fixtures work when plugged into another circuit and b) the other three dimmers and lights hooked up in the same box work fine and draw power from the same wire cable/breaker combination. The only things left that I can think of is that the electrician has either wired the dimmer switch up incorrectly or that there's some kind of flaw inside the switch itself. Does this make sense?



A friend also told me to double-check to make sure that the black wire feeding power to the light was indeed the hot wire, and it is.  If I touch it with the black test lead from the multimeter and put the red one to the neutral I show 120 volts. If I keep the black test lead on the black wire and put the red test lead to the ground - I also show 120 volts.



A final point. I know I'm not overloading the circuit - not even close. With all four dimmers maxed and every light on - including the test light on the track - I'd only be drawing 8 amps on a 15 amp breaker, besides which I'm only using one set of lights while I'm working on this problem anyway. This is a dedicated circuit, so there's no additional power being drawn away by something else.



So how am I getting 120 volts from this wiring, according to my multimeter, yet it won't light up ANYTHING and keeps giving off the indication that some kind of loop or short is being created every time I actually plug a light into the track? It's got me totally stumped.



Anyone have any ideas?
      

I am redoing my basement, and i am making the electrical runs for the recessed lights in the ceiling. I am using 14 gauge wire, and i have 16 recessed lights with 65 watt bulbs in them, however they are rated at 75 watts max. assuming someone after us may put in the max bulb, the total watts would be 1200, equaling 10 amps. When all of the new wiring is done, i am going to have an electrician connect the circuits to the circuit breaker (using 15 amp breakers) however since i am not comfortable doing this myself, and i would like to use the lights now, can i connect them to the existing 12 gauge wire (this will not overload the breaker... i already checked what else was plugged in to the electrical outlets).



to recap:

The power draw will only be 10 amps at MAX. capacity

existing wiring is 12 gauge/ 20 amp breaker

electrician WILL connect 14 gauge wire to breaker using 15 amp breaker



*THIS WILL BE TEMPORARY*
      

Appreciate any help with this.



Background:



- new to us old house, got three quotes for an upgrade to 200A service plus addition of three new circuits in conduit with receptacles (Chicago area, conduit is code in just about every town around, I have no issue with that);



- existing service to house was overhead, opted to keep it overhead and not bury it;



- the quote says, exactly: "Installation of a 200 amp 240 volt overhead electric service complete with riser, outdoor meter socket with a 200 amp disconnect, 40 position circuit breaker type distribution panel..." etc.;



I understood from discussing the work with the contractor we chose that install overhead service meant to include the work and materials needed to upgrade the line coming from the pole at the alley to the house to handle 200A capacity; paid 50% down on quote;



- the morning the boss and tech show up for the work, boss says we already have a 200A overhead, which I seem to recall the home inspector mentioning months ago before the closing (makes sense because the overhead runs to a single room addition put on several years ago), but boss was the guy who came to the house to quote the job in the first place, didn't mention anything about the existing overhead capacity at the time;



- the work gets done, seems fine; tech left without going over anything with us but whatever.



Final bill matches the quote to the dollar. There is no indication that there were any surprises during the work.



Since the quote says installation of overhead service and they didn't need to replace the overhead lines from the pole I think the final bill should be lower than the quote. The distance from the pole to the riser is about 40 feet.



Should I expect from the wording in the quote that the final bill should be lower than the quote because they didn't have to touch the existing overhead?



About how much lower?



We didn't go with the lowest quote, didn't beat him up on price and the total bill is quite a pretty penny, so I think he would be making good money either way.



I know there is no way for someone to tell me an exact dollar figure here based on a blog post, but I'd like to get some kind of idea so I can start my conversation about the final bill.



Thanks for any help out there.
