New Lighting From Scratch

hi everyone.



i am installing 4" recessed lighting throughout my main floor.  my house was built in the 40's and the previous owner installed drywall over the existing lath and plaster ceiling.  so I've cut a trench down the center of my room to drill floor joists to run wiring and cut my holes for the new lights.

the lights are fire rated and do not require insulated cans for a traditional installation in a drywall ceiling.



question i have is with the additional 1/2 to 3/4" of lath and plaster above the drywall, should these lights now have insulated cans or should i be fine with the cans I've got?  there is no insulation in ceiling.



any suggested would be appreciated.



thanks

Hi everyone. I'm new here, so I hope I am not posting this in the wrong place.



Is there a good book or site with instructions and tips for running computer networking cable in the walls in existing construction? I did it in my former house, which was a one story Ranch house with a big crawlspace. It was very easy. But my current house is two stories on a slab. Not only can I not go under the house, but I need to get things to the second floor. I want network ports in at least six rooms, covering both floors and spanning the width of the house. I can put the patch panel in the coat closet in the middle of the house.



I want the end result to look as clean as possible. I'm not ok with cables running outside of the walls. I am expecting to have to cut and patch a lot of drywall, but I'm sure there are right and wrong ways to go about this project. And ways that will result in as little drywall cutting as possible. And what about running perpendicular to joists? Is it ok to drill holes that way? Even if I do, that would require cutting a hole in the ceiling every few feet I think. I hope there's a better way.



What resources should I read?
      

I am currently remodeling a bedroom in my home for a new baby.  I have gutted the room and am replacing all the electrical and adding new recessed lighting.  The room will also have a ceiling fan, along with the recessed lighting.  I am looking for a single gang light switch that will operate the ceiling fan independently of the recessed lighting, with a dimmer for the recessed lighting.  I don't have room for a double gang box where the switch is currently placed, as there is a closet in the way.  Is there such a thing as a switch that will operate the ceiling fan and it's lighting on a normal on/off switch, with a dimmer that can independently control the recessed lighting?  I have checked with the local big box stores and everyone has told me I will have to run two switches.  Is this the case?  Any info would be greatly appreciated.  Thanks in advance.
      

I've been the owner of a 1930s era Colonial Revival that our first major project is to rewire the house. We have a 100A main box that is maxed out, a combination of cloth 2-wire, flex, and some cracking Romex along with some downright dangerous open wiring in the basement, tapped wiring in the kitchen and study, some gangboxes that were wallpapered over in the bedrooms that we assume were wall lights (we have similar wall lights in the bathrooms), inadequate outlets in most rooms, no GFI. Etc. Etc. In addition the bathrooms are small and lack wall switches or outlets (they have two pull-cord wall lamps, with one lamp with a outlet.



Here is a floor plan with electrical represented on the ground and second floor. Still working on mapping the basement and the attic (which has a 3/4 converted finished "bonus" room.



My Father-In-Law who is a licensed electrician has promised to gracefully donate a couple months of his time to rewire everything. Also a bonus in this is the majority of outlets are mounted on the baseboard trim and not in the plaster.



My plans are to go with a single 200A main, likely double the amount of outlets in each room, GFI where needed.



While I know some basics, I want to familiarize myself a bit more on what is the best approach to rewire. For instance should I look at running conduit in just one spot of the house, or should I run two on each end of the house? I plan to do some major remodeling of some rooms in the future, especially the kitchen and bath so what are the best ways to ensure I have an easier time with these remodels?
      

First off, I have read a majority of the posts concerning this subject and they have been very helpful and answered many questions, but I still have a few.



I am wanting to run power to a detached shed that is around 100 feet from the house. However, due to the location of my main panel and the easiest route to run the power, I am looking at running cable about 270 feet. I measured it out to exactly 263 feet, but figured it would be best to go longer. I am wanting to run at least 60 amps to the shed, as I won't be using it for nothing more then power outlets (basic power tools) and lights. Here are my questions:



1) What cable would be best for such a long distance run?



2) Would a 60 amp subpanel be sufficient for this job. I am looking at only 4 circuits: 1 for internal outlets, 1 for lighting, 1 for motion sensor light outside and 1 for external outlet. I am looking at the following panel:

I have seen some marked 70 amp and wondering if they make a difference:

3) Also, I will be installing a 30 amp RV connector circuit from my main panel  to the where I park my Camper Trailer, which is a run of about 75 feet. What would be the best cable for this sort of run under ground? Can I run both cable together in the same conduit until I junction if off to where I will be installing the plug for the camper?



4) Would the following be the circuit breakers to use:

30 amp - http://www.homedepot.com/h_d1/N-5yc1...&storeId=10051



I think that is it for now. Thanks in advance for all your help!!
      

QUESTION:  can I run (2) 14-2 romex wires in (1) 3/4 BX Armored cable?



SETUP: I am finishing my basement and a few main floor circuits are intermingled with the basement lights and outlets.  In finishing the basement, all basement electrical will be on its own circuit. Therefore, I need to rewire some main floor items.



For instance, the main floor living room outlets go through the den area below in the basement. The 3/4 BX cable goes through the ceiling to the outlets.



PLAN:  I plan to cut the armored cable shortly after it comes out of the ceiling (main floor floor) and just connect the first floor outlets in a series using the proper bushing and BX cable ends. I will strap the BX cable ends down and the romex as soon as it comes out.



The electrical inspector already gave me thumbs up on doing this for the electric oven and cooktop (bigger wires of course).



I searched and couldn't find anything to this specific question.



Any input?

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.
      

Hi,



I would like to wire a switch to be able to cut the power to the ceiling mounted outlets that feed our garage door openers. Running new wiring to them will be a bit cumbersome, so I am hoping to avoid that. The ceiling outlets are powered by light fixtures in the garage (one near by each outlet). There is a 3 wire romex cable running from the light switch to the first light and another one between the lights, and then regular 2 wire romex cables from the light fixtures to the outlets. The red wires in the 3 wire cables to the lights are switchable, the black wires are always hot.



I mainly want to be able to cut the power to the doors when we are away on vacation, and the reason for that is that one night both doors somehow opened up - I have no idea why. I'd hate for that to happen when we're away. Unplugging and plugging in the openers is a bit of a hassle due to the high ceiling.



I thought about wiring in a switched outlet so that I could just reach up with a long handle of some sort and switch off the power to the outlet. It would not be ideal, but definitely easier than getting the ladder out and unplugging the door openers.  However, there is possibly another option that I'd like some input on if anyone cares to comment. I believe I could wire in a switch on the wall next to the light switch that would allow me to cut the power to the black wires in the 3 wire cables. This would cut the power to the ceiling outlets and anything downstream from there (possibly an outside light, I would need to check on that).



My question is, are there any potential issues with this sort of wiring? Is there perhaps any code violation if both hot wires in a 3 wire cable can be switched off separately?



Thoughts?
      

Hey everyone - question about home wiring that was done when the house  was built about 20 years ago (which putting it delicately...is very  shoddy at best).  I'd like to think of myself as fairly knowledgeable in  basic home wiring...but this one has me baffled and I really hope  someone can help.



I am redoing a screened-in porch at the back of our house.  There is  currently a working outlet, and single-pole switch that turns on an  outside bug zapper, and a wire running coming into a second  switch...then leading into nothing in the ceiling (presumably for a  future ceiling fan / light install that was never completed).  I gutted  the entire porch and using one of those audible voltage testers,  discovered the wire than ran into the second switch / ceiling box did  NOT work. 



Not thinking much about it, I tried figuring out how the first switch  (to that outdoor bug zapper) was wired.  Most of the wiring for that  switch and the outlet I mentioned is behind the plywood sheathing of the  house...so it's near impossible to figure out where it goes.  Initially  it LOOKED like the power from the circuit panel came into the outlet  first...and then went out to the bug zapper switch.  (Why did I think  this?  The outlet had a B/W wire coming into it...and another B/W going  out back into the wall somewhere.  Tracing that wire along the basement  foundation best I could...it looked like it went right into the bug  zapper switch).  So wanting to completely eliminate the bug zapper  switch, I disconnected all of the wires that were connected to the  outlet to figure out which set was leading to it.



Here's where I got confused.  When I did this and re-tested voltage at  the outlet, one set of wires was live...and the other set was dead.  And  that makes perfect sense.  Yet the bug zapper switch STILL worked.  OK -  so my conclusion: the power for this bug zapper switch isn't coming  from the outlet.  No problem.  But just because I was near it, I decided  to also check that 2nd switch / ceiling wire combo...and what do you know - it was LIVE!



I got super excited it was working but then super baffled because I  didn't do anything to that ceiling wire at all.  In fact - all I did was  DISconnect 2 sets of wires at a nearby outlet. 



Confused but happy, I was ready to pack it in for the evening and  re-connected the incoming / outgoing wires back to the power outlet.   Flipped the circuit breaker on.  No issues.  BUT - now all of a sudden  the 2nd switch / ceiling wire that magically started working was NO  longer working - just like it hadn't been since I started this whole  process. 



Logic is telling me it's obviously got something to do with the outlet  wiring...since that's the only thing I messed with.  But why would the  ceiling wire all of a sudden become LIVE when the wires going into the  outlet were all disconnected?  It's certainly a first for me.  Can anyone help me figure this mystery out?  Thanks gang!
      

I'm preparing for finally calling in for my rough in inspection and was hoping I could get a checklist or at least some suggestions as to what work should and should not be completed for a rough-in inspection.  Does any wiring need to be spliced, wire-nutted, terminated within the panel or lighting or receptacle boxes?  My project was running power from main panel to lug and from lug to sub in detached res. garage and installing 4-5 lighting and recep circuits.
