Q:Hi,I'm looking to change the outlets and the switch and light fixture in a bedroom of a home built in 1948. The outlets are original to the home I think. Will I have to fish ground wire throught to the panel box for my new receptacles? Or just install new 2 slot outlets?Why the different looking wires?Is the older wire copper with a silver colored coating to indicate being neutral or is this an old aluminum wire? The hot wire is red plastic coated and looks modern to me.

you've got some good answers so far. if the wire turns out to be aluminum then proceed with caution because aluminum wire in small sizes turned out to be a terrible idea. it will need a special receptacle. if the wire is bx wire as described in your first comment don't bother with those greenies he mentioned because simply screwing your device into the metal box will bond the ground together. it uses the 6/32 screws provided as an excellent grounding means. you may want to consider using GFCI receptacles as well. I've never seen a new hot wire and old neutral wire like you describe and I've worked on a lot of older houses. before you get into trying to rewire your house realize that this is a very time consuming and aggravating project that will require two people who really should have experience doing this. if you do it then invest in a long (like 4 foot) drill bit and some glow sticks.

Q:So, I purchased a motion sensor light switch to replace the regular switches at my new condo. I have the wires exposed and I've identified the hot wire. My only problem is the hot wire (from inside the wall) is a single thick copper prong, whereas the wire for the motion sensor is split into like 15 different small copper wires.... I don't think the thick, single wire from the wall will work with the twisting wire connectors I purchased.... Am I able to just put the wires together and duct tape them??

You need wire nuts, conical plastic pieces with wire helical cones inside them... which sounds like what you have already. (It is not allowed to crimp solid wire - it weakens the wire.) Wire nuts come in different sizes; you will want the orange ones. To use the wire nut, lay the stranded wire alongside the solid wire, both stripped back about 3/8 inch, give the pair a gentle twist with your fingertips, and twist the wire nut on them until it stops or gets pretty hard to twist. Give a test pull on each wire.

Q:I want to make wire art but I'm not sure what type of wire to use

They also sell rolls of other wire, click on metals in the top sequence, choose one then choose wire.

Q:A street lamp weighs 200 N. It is supported by two wires that form an angle of 130° with each other. The tensions in the wires are equal.What is the tension in each wire supporting the street lamp?If the angle between the wires supporting the street lamp is reduced to 100°, what is the tension in each wire?

Problem 1: If the tension in the two wires are equal, the angle they make with the horizontal must also be equal. Always remember that a horizontal line is a straight angle; hence, it has a measurement of 180°. Let's look for the angle the wires make with the horizontal. 130 + x + x = 180 130 + 2x = 180 2x = 180 - 130 2x = 50 (Divide both sides by 2) x = 25° Each wire makes a 25° angle with the horizontal. We can now find the tension. The mass must be divided by 2. Using trigonometry, let's find the tension force. The divided weight of the lamp shall be the opposite side, and the tension force shall be the hypotenuse. sin 25° = (200 / 2) / Ftens Ftens = 100 / sin 25° Ftens = 236.62 N (Answer) The tension is 236.62 N in each wire. Problem 2: We use the same approach. 100 + x + x = 180 100 + 2x = 180 2x = 180 - 100 2x = 80 (Divide both sides by 2) x = 40° Each wire makes a 40° angle with the horizontal. Calculate the tension force. sin 40° = (200 / 2) / Ftens Ftens = 100 / sin 40° Ftens = 155.57 N (Answer) The tension is 155.57 N in each wire. Hope this helps!

Q:What Spark Plugs and Wires would optimize my MPG? 2000 Bonneville SSEI

any plugs + wires will help the mpg a bit if the plugs are gapped correctly before installation

Q:If someone were holding onto a high-voltage wire by both hands, why would his/her body have the same potential as the wire? How come his/her body would attain the same potential as the wire?

No however the guy`s physique would be on a similar voltage skill because of the fact the intense voltage cord and as a result would be situation to arching off to any conductor this is related to floor and as a result inflicting intense present day to bypass during the guy`s physique inflicting electrocution. the guy would be risk-free putting directly to a single intense voltage cord as long as he would not come close to or touch yet another merchandise that conducts present day back to floor. If the cord breaks there will be an astonishing arch on the factor of the wreck and can maximum probably leads to burns intense sufficient to reason death to everybody clinging to the cord at that factor. in case you have survived as a result far then with the aid of all skill throw the cord you're clinging to as far away out of your physique as achieveable because of the fact with the coolest fortune you're having the cord you're conserving stands out as the warm edge of the wreck and you would be electrocuted as quickly as you attain the floor.

Q:The application is a bathroom light and exhaust fan combination. The fixtures wires are thiner than the supply wires. Should I wrap the thinner wire around the thicker wire or should I wrap them equally around each other? Then can I put a drop of solder on before I put the wire nut. Or is solder not a good idea?

If the supply wires are solid and the fixture wires are stranded put the stranded wire slightly past the end of the solid, say 1/16. Then put a yellow wire nut on them. Tug on the stranded wire to be sure it caught. If the wires are both solid, try twisting the larger wire around the smaller one. It is tricky but if you let your lineman's pliers slip a little as you twist it should work. Cut back to about 1/2 to 5/8 and install the yellow wire nut. Time was wires were soldered together, but properly installed wire nuts are just fine.

Q:Where is itI have a 1996 Honda Accord with a pioneer deh-p6400 head unit. I tried to install an amp. Held the ground to soem metal and tried to get it to turn on. I tried the power antennae wire and it didnt' work. Nothing seems to work. I dont want to splice any wires or anything

hes right....all u have to do is continue the blue/white wire to the remote spot of the amp.

Q:Hi, I've got two new appliances (range hood fan/light and bathroom exhaust fan). Both are installed but not wired. My house is older, build in 1940s and the previous appliances were wired using the existing copper wiring which runs through the house. I'd like to electrically install these new appliances but am concerned about connecting the new appliance wiring (aluminum wiring i think?) to the copper wiring in the house.Is it safe to pigtail these two wires together? Or is there a better, more safe method?Thanks

You might find a holy war of electricians on this topic but to simplify. It is not safe to connect copper to aluminum wiring when the aluminum is SOLID core. Many new fixtures come with a silver colored wiring that is STRANDED and these are connected to copper wires as general practice without any problems.

Q:Found some electrical wiring resonably priced on craigslist but it says -----8 gauge (AWG), 3 wire, direct burry electrical cableDOES THAT MEAN ITS 3/0 WIRE? Because I need 3/0 wire direct burriedI am looking to buy some extra 3/0 wire and found some on craigslist for a reasonable price....

No this is 3 conductor #8 cable, (40A. /conductor). #3/0 is a LOT larger, (165A.). If you have to ask, you shouldn't be messing with cables that large.
