Q:I just removed a Australian light switch that I've never seen before that controlled a bathroom ceiling fan and the bathroom light. (both buttons on a single panel switch)I have a black wire coming from the switch box that has 2 other black wires splitting out from the connection point, one of each going to the fan and the light. And a single black wire going to the ceiling fan and a red wire to the light.I'm just putting in your everyday off/on switch one for each the fan and the light. any help? what are the positive and negative wires?

Here in the USA we use Black and Red for power (positive) , a white wire for a neutral and green (or bare copper) for ground. I am guessing that the red and black are the independent power wires and the other black wires are the main power. the use of a multimeter should be used to verify which is which. Since your putting in a single switch (which is a interrupter) where you have one black splitting to two, remove the 2 wires and make it a single wire and attach to the line side of the switch. Then connect the red and black wire for light and fan with a 3rd wire (tail piece) and attach the tail wire to the load side of the switch., Remember to test your power source first. If in doubt, hire a electrician. No one wants a fire!!!! Better to be safe then sorry.

Q:I have 2 connectionswire and wireless,im only connected to my wire how do I open a connection to my wireless?

You'd need a wireless router 1. Start Menu 2 .Connect to Go into wireless connections I.E. if your computer doesn't find the router that the wireless is hooked up to- than you need a WIRELESS ROUTER to do so.

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:if a wire of initial length, and radius has a measured resistance of 1.0 ohms. the wire is drawn under tensile stress to a new uniform radius of 0.25r. what is the new resistance of the wire?

assume the volume of the wire is constant cross sectional area = pi*R^2 A1 = PI * r^2 A2= PI * (.25*r)^2 = PI * .0625*(r)^2 = 16* A2 If volume stays constant, Length2 = 16* Length1 since resistance is proportional to length/area R2/R1= L2L1*A1/A2=16*16 = 256 The resistance now 256 times as great

Q:need to know how to properly wire this amp in a truck

wow I have never heard of this amp until u mentioned it. the ratings seem good. ur best option would be to call sonic electronics have them send you a manual on how to wire this amp. they sell this amp. I mean u ask how to properly wire it. wire it to get power ? or to the woofers ? red wire + goes to your battery. black wire - goes to your ground (not your battery) to the frame of ur vehicle. then u need a blue wire, your remote this wire goes to ur stereo's remote wire it should be the same color or it will be marked. but if u do not know how to hook up an amplifier u should go to a professional shop due to the fact if u improperly hook ur amp up YOU CAN START A FIRE IN YOUR CAR.

Q:wiring diagrams

Usually just find a spare socket to plug it into. Difficult bit is getting the plumbing right - read all the information supplied with the pump or look on the web before you buy it.

Q:I am replacing old 3 button (vertically aligned) light switch. There is 1 thick wire wrapped in white, 1 thick wire wrapped in black and 4 thin wires wrapped in black. I attached the white wire to the common wire screw and put the remaining wires around the screws. I am also replacing a toggle switch that will control the vanity lights above the sink. There are 4 clumps of wire coming through the box. The copper grounds are all twisted together, and there are multiple strands of white covered wire twisted together and then the 5 black cover wires and 1 white covered wires. After hooking it all up, it doesn't do anything. No lights, fan or heat lamp. What did I do wrong?

Q:I have a Speedaire 4B234 its currently wire to 120V but keep flipping the breaker and I have a 240V in the garage so I want to wire it to that. I have 2 blue wires, 2 red wire, and 2 green wires but the green wires are hooked together. One blue wire goes to Line and the other to Motor and same thing with the red wires.

I looked up the specs on the 4B234. Says it CAN be wired to 240. You will just have to follow the wiring diagram on the motor or with the instructions. Specs say it pulls 15 amps at 120 v or 7.5 amps at 240 v. Your problem now is that maybe you only have a 15 amp or a 20 amp breaker. 15 amps is probably the continuous running draw. The current surge on start up goes over 20 amps and is what is flipping your breaker. you will need a double pole (2 wire) 20 amp breaker. wire it with #12 wire. Say a green, red, black. (or you can use blue and red) Green is always ground (should be). 240 volts works by being 2-120's out of phase by 180 degrees. One wire is pushing (+) while the other is pulling (-). You hook one wire to the motor in and the other to motor out. Running 240 will increase your efficiency.

Q:Are those coils of wires in an electric fan magnetic?

Q:when checking white wire at the box it is cold when checking at the light switch it has power i am confused

The white is the neutral and has no power in it from the breaker box. When you check it at the light or switch you are getting power back through the light bulb.
