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.

it is normal for a house built in the late 40's --- it was thought, at that time, that the aluminum wiring was cost effective and the most up to date === it would be wise to pull new wire and that would be 12 gauge with a ground [[ two wires, a black

Q:Green (ground), got it.Black (positive), got it.White (common), got it.Gray wire with like a black fiber in it, what is this? This is a pendant light so my guess is its just a filler wire to bulk up the cord it hangs from, am I right?

The gray wire is used as a physical support for the light fixture. You tie each end to the light fixture and to the box where the power wires are connected. This is so that you don't use the power wires as a physical support (hanger) to hold the light in place. Think of a swag lamp from years ago. The lamp hung from a chain connected between the lamp and the ceiling. The power cord never supported the weight of the lamp fixture. The black fiber in the gray wire is a strong cord.

Q:Help me, please! I have an old air conditioning system...made in 1985, and the condenser fan went out. Long story short, I bought a new fan and I don't know how to hook it up. The old fan had 4 wires coming out of it: purple, black, green, and brown. The green is the ground and the brown and the purple went to the capacitor, black to power. Then there were two smaller black wires attached to the capacitor and they lead out to other components. My new fan has a green wire, a white wire, a black wire, a brown wire and a brown and white striped wire. My problem is this: I don't know where to attach the white wire or what to do with the two smaller black wires that were attached to the old capacitor. I was told by the gentleman who sold me the fan that I splice the white wire to purple wire - then do I hook that to the capacitor? What do I do with the two smaller black wires that lead out to other components??? (Cap them off???) I am confused and need some advice!

I suggest having a tech. wire it in for you, but your new motor should be wired this way, the black and white are your hot and common, so 208v unit, hook black wire to L1, white wire to L2, green is a ground, ground it to cabinet somewhere, brown goes to one side of run cap, brown/white goes to other side of run cap. if you are unsure about how to swap it out then seek someone with some electrical background or an hvac tech., dont hurt yourself or your equipment by doing it improperly, good luck with it!

Q:What is wire Harnesses?

A wire harnes is a set of wires that has all the conductors needed and can just be installed into something. There's a wiring harness in your car. They don't install the wires one-by-one. A harness is built for the product and is installed like any other part. There can be many branches on a wiring harnes to go to different places in the product. There may be more than one harness. There could be one for power, one for communications, etc. This is more efficient than installing separate wires.

Q:To help clean things up and make wiring a little more simpler on my jeep i got a fuse/relay box off an old junk car. i want to wire my off road lights into this relay box but i'm not sure what size wire is in the box it appears to be either 18 or 16 AWG one place said to strip the wire and measure the wire another says measure in the insulation. i'm not sure what to do. but if it is 18 awg would it hurt to go to a bigger size after the fuse box to my lights or should i rewire the whole box?

For okorder /... Wiring gauge always specifies the diameter of the WIRING not the insulation, since the insulation thickness can vary. You would have to strip the wire and measure the bare wire with a gauge. You can also look at the printing on the insulation for the gauge. Look for something like AWG 14 etc. You can buy a standalone headlight harness that contains the relay and wiring for aftermarket lights. I would recommend running both positive and negative wires all the way to the battery for maximum current.

Q:A wire is 1.5 m long and has a diameter of 1.5 mm. The stretch modulus of the wire is 6.2 x 10^10 N/m^2. If a force of 400 N is applied to end of the wire then the increase in length of the wire is???please help, thanks

The stretching of wire by longitudinal force: If F force applied across the crosectional area A of wire of radius r and lenght L then the wire elaogates in the dirextion of force Stress P = F / A A = pi* r^2 = (1.5/2)*10^-3 = 7.5 *10^-4 m^2 strain produced = dL / L = increase in length / original L Young's modulus or elastic (stretch) modulus for the maretial, within elastic limits, Y = stress/strain strain = stress / Y dL = F * L / A * Y = F * L / pi (r^2) * Y dL = 400* 1.5 / 3.14 (7.5 *10^-4)^2 * 6.2*10^10) meter dL = 0.005479 * meter dL = 5.479 millimeters increase in length

Q:does anyone know what wires go on which post on a 1995 chevy lumina 3.1 starter? it was off when i bought the car and im lost. i cant find a straight answer anywhere. a picture of the wiring in question is an instant best answer lol

it only has on wire and its not a very big wire shouldn't be that hard to find follow the wire off the battery to the solenoid then its one of the wires off of that

Q:I have a wire coming up from my basement that has 3 wires (red, green and yellow). I want to connect cat5 wire to that (twisting the wires together) and run the cat5 to an RJ45 box. What's my diagram going to look like?

Cat5 requires 4 wires (two pairs) - you cannot use old telephone wire. second, if the old phone was was 2 pair, you still could not use it. Cat5 is good to just over 300MHz. The old voice grade JK cable could not transfer data very fast. Just use the old phone wire as a pull. Connect a new run of Cat6 to the old wire and pull the new wire into place using the old wire as a pull string.

Q:I got the Rem wire down connected it to cd deck.But what does Rem stand for and what does it do?Remote Wire? what the hell it do where it run off?

The blue and white wire on the back of car stereos is not a remote wire, it is the antenna wire for power antennas. Which does not require 12 volts to power on the antenna motor. The remote wire is the same thing as the REM wire, REM is short for remote. This wire is used to send a 12 volt signal to external amplifiers to turn them on when the stereo is turned on.

Q:1 green wire, 1 black with red stripe wire

Green wire = positive Black with red tracer = negative
