Network Cable In Existing House

Okay, I am fairly new to wiring but its not the wiring I am wondering about.  It is running the wires.  I have 2 rooms in my house, 2 story and an attic, on the main floor that doesn't have any overhead lighting, only can use floor or table lamps right now.  The ceilings are about 10 feet tall.  There are outlets in the room so I do have power I can tap into for the lighting, but how do I go about running the wires up into the ceiling?  I do know I have to cut the hole for the lighting but will i have to put cut flaps in the drywall where ever there is a brace to drill holes to run the wires.  I am going to go from the middle of the ceiling straight back to the wall and then down to the switch that I will put in and then down to the outlet to tap into for the power.  I am just trying to do this the easiest way to minimize any drywall repair that will be needed.  Any help or suggestions from anyone is greatly appreciated and if you have questions please ask and I willl try to answer them.
      

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

I am running power about 180 feet to power a 60A subpanel in an outbuilding. I am expecting to use 2-2-2-4 AL. The run is underground for about 150', and the balance through crawlspace and basement to the panel. My question is: can I use a sheathed cable such as SEU in the conduit so I can simply continue (unconduited) under the house, or do I have to run URD in the conduit to a juction box and change to a sheathed cable to run under the building?  Or can i run URD in the conduit under the house to the panel (this would be less preferred). Thanks
      

I have a 50 foot hdmi cable that is hooked to my TV, run through my wall to my basement then over and upto a closet where the cable is hooked to my surround sound. Unfortunately my basement ceiling is finished in drywall and there is no access to replace the cord. To make a long story short a cable TV provider came to my house to change out a box and broke the prongs on the hdmi cable. My question is, can HDMI ends be spliced or replaced somehow without replacing the whole cable.
      

I have a 15 amp circuit feeding a bathroom and I want to upgrade it to a 20.  Can this be done without opening up the sheet rock walls and space between the first story ceiling and second story flooring?



It was wired, when it was code in the early 90's, with #14.  I am thinking that I could go from station to station and connect the end of the new 12 to the end of the old 14, and then pull it through BUT PERHAPS FOR STAPLING, assuming the cable is stapled every foot and a half.  If it is, and the run isn't too long, is it often possible to just tug on the cable to loosen the staples?



Assuming that can be done, do I have to open up the walls and ceiling to staple the new #12 cable to the framing. 



I am trying hard to avoid opening the drywall.  The newer paint in this particular room is impossible to match and I would have to repaint the entire room should I have to cut the wall.
      

Hello,



can cables be run along the side of 2x4s which run along bottom of rafters? Sheetrock will be put up later on - attached to the 2x4s.

These are vaulted ceilings.



I know about the issue with nailing into cables in the walls and the requirement to install nail plates but how does this apply to the ceiling in this case (shown on attached picture)?



I'd like not to drill holes into the rafters to run the cables.



Will inspectors be ok with this?



Thanks
      

So we just bought a circal-1930s house, and one very large project looming is redoing the eletrical. The house has a mix of BX, cotton-wraped romex, and some very cracked romex running around the house. combine that with some very odd additions for outlets, bad light switch placement, it's just going to be a large project.



My father in law, a licensed electrician, has promised to do the rewiring of the house this summer. The problem is I plan to do some major renovations in the coming years (namely the kitchen).



I am already drawing up floor plans now so I can stategically think of where to put needed outlets, but should they be installed at this time? Is it worth the headache to install new outlets now and put them in their proper locations when the reno comes?
      

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?
      

What is the typical sized hole for running NM cable through a stud or top plate?  And how many NM cables can go through that single hole?  Also, how many cables are allowed per panel connector?  I will be running all 12/2 NM.
      

Hello All,

Hopefully I am posting this in the correct forum!

I am new to the forum and I have a question I would like to pose.

I am trying to make an extension cable for my telescope hand control.

I have had good results with the 25' length  but it is to short . So I made another one 50' in length but it give me connection error codes. The cable is correct as it worked for a while .I am using an rj12 6pin connector with cat5 cable(24awg). The power supply is 12V DC with 2.5 amps running on house AC.

The question is: If I put a different power supply on that is 12v DC using 5.0 amps will the increase in amperage effect the DC current flow?



Thanks,

Don
