Does anyone here know how to run electrical wiring in a house? (need some advice)

My wife and I moved up to a better house a few months ago and we're ready to start doing a little remodelling. The first thing I want to do is add some new lighting through-out the entire house. For example in the living room I want to add some recessed lighting, I'd like to install sconce lights in the hallway and some accent lighting in other areas through the house. My question is whats the best way to put in the conduit and new outlet boxes without doing to much damage to the drywall? Also how do I know when there is to much load on a circuit? Is there a rule to determine how much should be on one breaker?

Thanks for any info



EDIT: I'm also gearing up to run ethernet and video coax through the house. Whats the best type of wire to run for a network these days? (I plan on hosting a video server in my basement and sending large files to about 4 workstations scattered through the house so I need good bandwidth.) Also whats the best kind of coax to use for sharing a satellite or digital cable signal through out the house? My goal is to have 2 sets of video and internet terminations in each room of my house and we have a total of about 10 rooms that need to be wired.
 
Plenty of helpful books and seminar-type things at Home Depot/Lowe's.

But, you'd think an 'arkitech' would know that 😉

There's a website somewhere (cannot remember the name) that is a bunch of useful information for like DIY stuff...dang...can't remember it!
 
Home depot sells a book called "Home Improvement 1-2-3" that I was going to go pick up. Flipped through it a couple times while waiting in line, and it's VERY thorough. It'll probably have what you need.
 
as for the load on a circuit breaker - put as much on there as the wire you attach to it can handle. I.E. don't have a 15-amp breaker on 18ga wire. 🙂

You know theres too much load on the circuit when the breaker flips, of course. BUT, if you used a too large breaker with a too-small wire, the wire will catch on fire, and the breaker will never flip.

good idea I need to find one of those books, I wonder if I can get a free one from the village building dept.

I had one of those books but now I can't find it, I think one of my brother-in-laws may have borrowed it
 
CAT5e is the de-facto network cabling. It will run full gigabit speeds, and is available at Home Depot in single foot quantities, 500 foot quantities, and 1000 foot quantities. Just buy 1000 - it'll only run $50.

Electrical wiring is dicey for a first time DIY. I personally recommend _A SINGLE OUTLET TO A BREAKER_ - and NEVER tap overhead lighting into an outlet. You will hate yourself for it. Also NEVER switch an outlet. You'll hate yourself worse for that.

Chances are, you'll never need the capacity provided by doing a 1:1 outlet:breaker ratio, but it's a convenience thing. It's not as though breakers are expensive. Also, you may want to look into installing a 220v circuit or two - just in case you ever need some euro hardware.

Yeah, pick up the phone and call an insured/bonded electrician.

I'm in a money saving mode these days, although it has crossed my mind to just call an electrician

yikes

I did'nt realize that to big of a breaker would burn up a small wire. I think I definitely better find a code book on electrical.

interesting, I know I should'nt combine an outlet and light to the same circuit or switch but I thought it was ok to run multiple outlets to one breaker

I'm cheap myself.... but electrical wiring is not something I'd do myself due to my fear of electricity and that sometimes, you need to get a permit to do works like that.

I've done some minor wiring before and I guess as long as you understand some basic rules its not overly dangerous. I plan on doing some reading over the next few days to make sure I know exactly what I'm doing.
 
id say, wire lights in one room to a breaker ,and the outlets in one room to a breaker, although you could do like 1/2 the room to one, other half to another, like maybe 3 to a breaker. and outlets in a room are always good, the more the merrier is what my dad seems to do, and it does allow for reconfigurations if you dont like where the tv is at or whatever.

You can do all of this yourself. Pick up a book at Home Depot/Lowes and read throught it.

Plan out what you want to do.

Then, make an appointment with your city's electrical inspector. Talk about your plans. Ask what he'll want to see when he does his inspection. And buy a permit.

The permit and inspection is protection against your own insurance company.

On that same line I would check your city ordinance because where I live it is illegal to do your own electrical work.

1. In some areas i've heard it is illegal to do wiring yourself ... you have to hire an electrician. Check with your local building department.

2. Conduit is ussually not required for residential wiring. Hopefully you have an attic or crawlspace above or below the areas you need to get new wire into. Then just drill through the top or bottom plate to feed the wire up into the wall cavity, and fish it out through your hole in the drywall. If you can map out your existing circuits sufficiently, it may be acceptable to add some of the new outlets or lights to existing circuits instead of running a completely new circuit. If possible, try to keep thing in interior walls ... it's a bitch trying to fish wire through insulated walls.

3. Check out the Code Check books (http://www.amazon.com/exec/obidos/search-handle-form/002-9845149-4911240). Home Depot carries them. They are a general overview of the National codes that most local codes are based on. Also check public libraries for the actual codes. You won't find them online, and they're damn expensive. I also have a very good wiring book ... I'll get you the title when I get home.

4. 1 outlet/circuit is WAY overkill. A decent wiring book will help you estimate circuit loads. As others have said, you MUST match the breaker to the wire guage ... 15AMP = 14 GA, 20AMP = 12 GA. You likely won't need anything beyond that for the kind of stuff you're describing. Remember, for kitchen, bath, and garage circuits, you have to have GFCI breakers. Also, new code requires something called an arc-fault breaker in bedrooms.

I think it is ussually accepted to keep outlet & lighting circuits seperate. But in a remodel like this, I wouldn't get to hard up about it.

If you're going to be rooting around in the ceiling anyway, I'd consider putting in direct-wired & interconnected smoke alarms. They are required by code in most areas now I believe (for new construction and major renovation) and are just a good idea. If one goes off they all go off, no batteries to change, and you can get combination smoke/CO alarms as well.
 
Here's an interesting question. I have a computer room on the second floor of our house. I want to run CAT5 down to rooms on the first floor of the house. My plan is to go up into the attic and try to run the cable inside the walls to the first floor. The question is, how do I go from the second floor to the first floor? Do I need a 10ft drill bit to drill through the floor plate of the second floor. My other option is to go into a closet on the second floor and try to drive through the plate from behind the base molding. Any other ideas?

Knock out a chunk of drywall big enough to reach in there with the drill. It's not that hard to patch it back in, but it'll need some paint.

Ignore that advice (except the cat 5e, and even then, why not consider a wireless network? If you've got the money, and want it wired, go with cat 6)

There are quite a few questions I'd consider first... What do you have coming into the house? (100 amp service? 200 amp service?) Also, how many floors in the house? 1 story with attic crawlspace = easier to run the wires.

Check codes.. I can't remember how many outlets you can have per circuit, or how many ceiling lights per circuit.
In my house (I rewired the whole thing), I had 1 circuit per room, except 2 in living room, 2 in dining room, 2 in upstairs bath, and 3 in kitchen, plus 2nd floor has 1 circuit for all the ceiling lights (and ceiling fans), same for 1st floor. Kitchen, bath need GFI circuits. EVEN IF your house was built before GFI was required, do yourself a favor and have a GFI outlet put in. Ask in another thread if you don't know how one protects you. (you can put the GFI outlet in the first outlet in the circuit, then have the rest of the circuit run off that outlet; you don't need a gfi receptacle for each outlet in the circuit)

You should be fine with the ceiling lights in half a dozen rooms or so on the same circuit. Personally, I would figure out the shortest total route or most convenient route to get to all the lights, providing them with the electric. Then, I would run another wire from the light to the wall switch. The neutral needs to be electrically hooked up from the supply side to the light, as well as the ground. The hot wire going to the light heads out the branch to the switch. The return wire from the switch goes to the light. Code dictates which color wire you connect the hot to at the light to go to the switch, but it really won't effect anything. I do remember that you have to wrap a couple inches of the white wire from/to the switch with black electrical tape to denote that it is the hot wire.

Should be an relatively easy but very time consuming project for the DIY.

MOST IMPORTANT!!! MAKE SURE YOUR CONNECTIONS ARE TIGHT TIGHT TIGHT!!! Loose connections or bad connections lead to increased resistance, which leads to increased heat. Increased heat leads to fire. Fire leads to death. Lazy electricians use the spring clips inside the outlets... screw that. All you have is just a little razor blade making the electrical connection. Not sufficient as far as I'm concerned. Use the screws on the sides of the outlets. Gold colored is the hot side, silver colored is the neutral side, and always ground the outlet and the outlet box.

Some codes (or maybe national code) says that you can't go directly from the wire to the outlet, then from the outlet back out again. You have to use wire nuts and pigtails. Screw that (unless it has to be inspected). Just don't use the little holes you push the wire into.

Don't even bother with 14 gauge wire... given the price, just get a 250 foot spool of 12 gauge. Then, if you should ever decide you have something that requires a 20 amp circuit, you're all set and don't have to run new wire.

 
Oh geez, and I forgot the most important part of your question: New outlet boxes - they make boxes specifically for remodeling. Use a template (or trace the box), insert into wall, and turn some screws and it fastens itself against the back of the drywall.

Combining an outlet and a light to the same switch isn't a taboo, its just annoying, because if you have anything plugged into that outlet, whenever you turn on/off the light, that thing goes on/off, too, and a lot of electrical components don't take well to cutting off the electricity.

Multiple outlets on one breaker is fine - most houses actually have that, but its easier to manage by having multiple breakers - if one flips, you can quickly figure out whats going on.

Oh, BTW, make sure you know the relation between amperage, wire gauge, and the like.
here is a useful chart relating various gauges to their safe current loads.
