Electrical Wiring

By Tim Carter
©1993-2008 Tim Carter
Summary: Electrical wiring is a job for a person with experience. You can start an electrical fire very easily if the wiring you install is not done to minimum national electric code standards.

Added a bar counter top to my existing counter. My problem is I cannot add electrical outlets to this area since there is not enough wall area. Is there any products like strip electrical outlets that can be used?

Yes! Go visit a real electrical supply house, not a home center.

Hey I have a question with the wiring. I'm wondering if I can use the same source for the lights in a room as the receptacles. In the end leading one source from the main source to each room. Or do lights need their own source and receptacles their own?

Dan,
I do believe that the National Electric Code allows this. But many seasoned electricians will probably agree it is not a good practice. You should have two circuits feed a bedroom and split the receptacle load between the circuits.

We have a 28 year old home we purchased two years ago. All the rooms are equipped with baseboard heaters. Since the home is rather large and open concepted, I find these appliances are rather inefficient in heating the space. Mind you we live in Canada and the winters have an effect on how we regulate the thermostats but we do keep all set at 68 degress.

My question is, one of the home centres is advertising 220V 2000W wall convection heaters which are compatible with any line voltage thermostat. Does this mean we could replace the existing baseboards with these new devices?

Thanks

Melissa,
I can't really answer with confidence as I would need to inspect your home and its wiring, breakers and/or fuses, etc. You need to involve both heating and electrical professionals and have them evaluate what you have and if the units will really achieve your goals.

what is the the latest in electrical wiring

I changed my light and now the switch does not switch the light off!
I thought I remembered how the old light was wired but maybe I got something wrong? Two pipes coming out of the ceiling. One pipe has 2 reds and one green coming out of it, the other has 1 red, 1 green and 1 black. Originally the 3 reds from the two pipes went to the red of the light, the black went to the brown of the light and the two greens from the ceiling just connected to each other, without going to the old light. I did this for the new light and also tried all other possible combinations and the best I can get is that the light goes on, but the swtich does not switch the light off! Do you have any ideas?

Frank,
It sounds like you are dealing with a ceiling fan light???? Go to their website for a wiring diagram that shows all of that spaghetti you are dealing with.

Thanks for getting back. No, both the old and the new fixture are simple lights, with 1 brown, 1 blue and 1 green wire. The problem is in the two pipes coming out of the ceiling. Usually there is only one pipe with just three wires coming out. I have never seem two pipes, each with different wires. I think that one is for the light and the other has something to do with the switch and that, for this reason, they both need to have some wiring going to the light.

We are installing custom cabinets in our home office. Unfortunately, one of the cabinets covers 75% of an existing electrical wall outlet. I'd like to move the outlet over about 12 inches, but there isn't enough slack in the romex wiring. Can I splice a new cable in the existing outlet and use it to feed the new outlet?

Jim,
You need to clear that with your local electrical inspector for the code-approved method.

It sounds like a 3 Plate rose as used in the UK, The 2 reds in pipe 1 are feed to switch and switch wire back to light, connect red from one pipe and red from other pipe together. remaining red to light (Switch Wire) black connects to Brown of fitting (Neutral) all the greens go together.

Hope that helps if the light is still on

Dan, although you are allowed to have lights on the same circuit as the outlets it is not a good practice for this reason, if you trip the breaker because of an overload you will lose your light and may not be able to see. This may not seem like a big deal until it happens at night or in a dark area of the house.

Hello, I need to know is there a way to safely connect two switches ( one to plugs,one to lights) with one power feed from the breaker?

Steve,
Yes, there is a safe way. In your case, call an electrician.

Funny about the above post. I just wired a lightswitch/outlet.. and the outlet works.. the light works.. but the light wont shut off.. any hints?

Deanna,
You didn't break off the small tab that connects the two brass screws together on the outlet. Get rid of that tab.

please help-i'm trying to install a dimmer switch in a loop system where normally the neutral wire becomes hot when regular switch is energized, but after hooking up the one black dimmer switch wire to the one black hot wall wire & the other black dimmer wire to the house neutral wire, it sparked & blew out the dimmer switch & tripped the breaker. A regular single pole switch works fine, my house was built ni late 40's. Any ideas to whats going on?

Anthony,
I am not confident in your skills and am wary about giving you advice. You better call an electrician this time.

I have one of the square kitchen florecent lights off center of a kitchen island. I would like to remove it and put two hanging lights over the island, one light on each end. How do tap into to use the same electrical cable for both lights, that is currently being used by the current light fixture? I will be taking down the old light fixture.

What is the max number of connections that you can make in a junction box? I am using 12 gage wire and the run from the basement to the attic is about 25 feet.

Dear Bob, Every time my den ceiling fan is on for several hours, the metal switchplate gets really warm. It is a dimmer switch & maybe not installed properly? What is causing the heat & how much would it cost to get an electrician to fix it? Sounds like a house fire to me! My home was built in 1985.

I am converting from a fluorescent fixture to an incandescent fixture. I have the following wiring to deal with in wiring my new incandescent fixture which has only a connection for a white and black wire. The wiring coming from my wall is two black spliced together, two white spliced together, one ground (green), and one red wire. My question is, what do I do with the red wire? Thanks!

Hi, you seem to have a great grasp on electrical. Are you a Certified Electrician or take courses? I Love all aspects of electrical and would love to further my knowledge.

Cappy,
Thanks. I obtained this knowledge through reading, experience and a few zots. Residential electric is the easiest. Rest assured that commercial and industrial electric is far more complicated. Go to your library and online and start educating yourself. Then consider taking some formal classes at a local vocational school.
