Q:My light switch has three sets of three wires (like conduit).. there are three black wires, three white wires, and three bare wires.. and I don't know how to hook up another light switch because it's near impossible to get three wires around a screw terminal. My boyfriend (works in maintenance) hooked a light switch up (one that you put the wires in a hole and then screw) except for the bare wire where two wires are under the screw terminal and the third is wrapped around the other two bare wires. The lights will stay on but when you turn the switch off, it kicks the breaker.. can anyone tell me why it's doing that? Thank you.

What it sounds like is happening there is that the switch box is the main feed for the room. You have a set from the panel, a set for the light fixture, and a set that are downstream, such as for an outlet. You need to determine which set is which. Then cut a piece of black wire and a bare copper about 8 long. This is how the connections are made: TURN THE POWER OFF. Then connect all of the whites together with a wire nut. Connect the new bare copper to the other grounds with another wire nut. Then connect the black from the panel, the downstream black, and the short black together with another wire nut. The black to the light fixture and the black pigtail (short wire) connect to the 2 brass terminals on the switch. The bare copper pigtail goes on the green screw on the switch. Reinstall the switch in the box, turn the power on, and check your work. If the light stays on at all times, but the outlets only work when the switch is on, those 2 wires are reversed. Turn the power off, switch the wires, and you should be good to go. Hope this helps.

Q:the plug only has room for black,red,ground wire.. what do i do with the white wire

There okorder /... is a 3 wire plug used for 208 or 240v (there is no 220v in the US). It has two hots (gold screws) and a ground (green screw). A typical 10-3 cord has a black white and green white, connect the green wire to the green screw and the black and white wires to the gold screws. An L6-30 is not compatible with devices that have a 240/120v configuration that use both 240v and for 120v and need a neutral connection, for this you would need to use a 4 wire L14-30. Also be aware there are some special rules about ranges and clothes dryers, please update you question if that's what you are dealing with.

Q:to which wire in the back of my car radio do i hook my remote wire to from my amplifier?

I also have a 2006 Toyota Corolla CE with an computerized transmission. If I force it somewhat confusing the worst gas mileage i'm getting is 32 mpg. the utmost i are becoming so a ways became 40mpg in a mixture of 75% city/25% highway making use of. To get that 40mpg i became hypermiling without doing something unlawful or fairly risky (like drafting semi automobiles). On customary although my gas mileage is usually 36mpg. The hypermiling I did... No velocity above fifty 5 mph. Manually cycle the A/C. flow away it off until i could no longer take it anymore then turn it decrease back on for 5 - 10 min. Coast right down to purple lights to make a green. Racing to a purple easy (as many drivers do) is pointless and wastes gas. No rapid acceleration. Coast right down to end signs and indications attempting to time it so i'm next. If no longer a minimum of i did no longer could wait diverse turns to be first in my lane. With wintry climate drawing close i'm going to attempt yet another around of hypermiling and notice if i can get extra advantageous than 40mpg. :)

Q:I bought a new light that holds two light bulbs for my bathroom and quickly took off the old light. I then noticed that wall had three wires coming from it, a black, red, and white. The light however has four wires coming from it, 2 whites and 2 blacks. How do i wire this properly so both light bulbs can be turned on and off simultaneously?

Since you have a black, red, and white wire coming out of the wall, this tells me you have a 3-way switch (meaning the light can be controlled by two different switches, correct?) If you only have one switch operating this light, then one of the wires may be (against building code rules) used as 'ground'. If only one switch is used with the light, then you'll need to switch the breaker off, then pull out the switch and see if a wire is attached to the green screw (ground). Black wire: Hot Red wire: Hot (three way circuit) White: Neutral Green or bare copper: ground

Q:how are lights grounded on a car? Seems like all the wires to the light have electricity running to them.

if they all had power running through them they wouldn't work. sometimes they use a relay to make a ground. would help if you said what you are dealing with.

Q:I just bought an aftermarket cd player for my Grand Cherokee and I would rather not have to cut and strip wires so I want to get an wiring harness adapter. My question is, can I just get any wiring harness adapter or do I need the direct connection adapter that is specifically made for Chrysler to Kenwood?

You just get the jeep wiring adapter and then solder or use crimp caps/butt-connectors to connect the wires to the aftermarket harness that comes with the aftermarket headunit. Also, depending on what year Jeep you have you may need an antenna adapter. AND I believe on the Jeeps (like the chryslers) there is not a usable ground wire in the factory wiring harness which means you will need to ground the aftermarket ground wire to the chassis via an existing bolt or drilling. Or, if the stock radio has one of these metal-mesh things affixed to the back, you can use that thing as well. But when you match up the Jeep harness you buy to the factory harness and you will be able to tell if there is ground wire in factory harness.

Q:why do screen filters have wires with them?

For Earthing to stop static Electricty, connect the wire to the Casing

Q:Okay so my question is how would I wire these in a ported box with 2 terminals on each side of the box? Also, is the quot;Bridged Wirefeatured in the diagram negative speaker wire? Thanks.

Bridging isn't something you do with the subs wiring. It's the way you wire them on the terminals. Each amp's manual should tell you which terminals are the bridgeable ones. That's a mono amp. There's not much you can do there with bridging etc..Try looking for a 2 channel bridgeable amp and then worry about wiring the subs. Not sure why you would want two terminals on both sides of the box anyway.

Q:Why do some vehicles have more than one starter wire at the ignition switch?

The extra wire activates the fuel pump while cranking. The run position only lets the fuel pump run if it sees signals from the cam and/or crankshaft sensors.

Q:(a) A copper wire and an iron wire have the same length and same diameter and carry same current I. In which wire is the electric field greater?(b) Can a 1mm in diameter copper wire have the same resistance as a tungsten wire of the same length?[Use p(copper)=1.7x10^-8 ohm meters, p(iron)=1x10^-8 ohm meters, p(tungsten)=5.6x10^-8 ohm meters]

a Since copper has higher resistivity than iron, the voltage drop in the copper wire with the same dimensions as the iron wire is greater, meaning more Volts/meter in the copper wire so the E field is greater in the copper wire. b Resistance is proportional to length, resistivity, and inversely proportional to diameter. Increasing the diameter could compensate for a material with higher resistivity. So the answer is yes.
