Q:What role does the neutral wire play?

A neutral conductor is used to provide two different supply voltage levels. Three-phase application: A 3-phase transformer with the secondary windings connected Wye with a line-to-line voltage of 480 V. If a neutral conductor is connected, the secondary would supply 480 V and 277 V (line-to-neutral). 480/1.732 = 277. Single-phase application: A single-phase distribution transformer with a secondary voltage of 240 V. If a neutral conductor is connected at the middle (center tap) of the secondary winding, the secondary of the transformer would supply 240 V and 120 V.

Q:want to get ready to solderis the fuzzy stuff the wire? or the shiny (positive green and negative red color) the wire? sorry i know its a noob questionlet me knowthanks

wire is metal and metal is orange or silver . The fussy stuff is string

Q:How can u do a wire transfer? Is there anything extra that is needed to do this? Are you able to make a wire transfer from your home computer?

Start from the financial institution where the money will be transferring out. You will need to sign some paper to authorize the transfer. If the transfer isn't urgent, you make also check to see if the institution could handle ACH. Money transferred through the clearing house usually takes a couple of days longer, but cheaper and possibly free of charge. Best wishes.

Q:what size wiring should i use to wire a plug in for a dryer?

if the dryer rateing plate says 220 volt 30 amp you can use # 10 stranded wire/ romex 2 colored wires and 1 ground (bare) or insulated green wire.

Q:wire diagram and manual

a small boats wiring cant be very complicated. If you're needing to replace it get a book called Small Boat Wiring or a similar. If you're trying to find a fault with existing wiring simply trace the existing wires remake all the connections as you go. I suggest you pull the lot out redo it properly. Except for the electric start you dont need super heavy cabling for a small boat. Tinned multi strand wire with a core diameter of about 2 mm is fine. Get a roll of red one of black ( or use red/black figure 8 cable) From the battery fit a service fuse of about 15 - 20 amp in line with the positive cable right near the battery. Use only properly crimped screwed or soldered connections. If the connection is ever likely to get wet then cover the connection with a piece of heatshrink tubing with a good smear of neutral cure silicone inside it. The silicone should squeeze out both ends of the tube when you shrink it. Dont make any joints mid run ( never in the bilges). Make sure the wiring is secured where it is out of the way is neat. Support the wire near the connections. Run from the switch panel to each item as a separate circuit, dont daisy chain. Give each item its own cable including the return (black wire) brought back to the panel. Be neat make a permanent record of what you've done. Fuse each circuit with a fuse rated about 50% above what that item should draw. Always carry plenty of spare fuses.

Q:do i need a different wire for in-wall speakers or a regular speaker wire

Regular speaker wire will work for in-wall speakers.

Q:I have an immersion heater in my hot water cylinder (UK airing cubbard), but the wiring isn't connected. But, I seem to be missing a small piece or two. The previous lead wire from the timer/switch is stil there and has two wires in it. Does someone have a generic wiring digram showing which wires connect to the thermostat and which wires connect to the heating element? Thanks!

Normal wiring with two connections on thermostat, on from timer and two on element would be a single wire from one of the timer wires to one connection on thermostat, one wire from other connection on thermostat to heater connection, then one wire from other heater connection back to remaining connection on timer. This is if the thermostat is high voltage and not a low voltage signal to a controller perhaps on the timer.

Q:Can I use 12-2 gauge wire on a 10 amp breaker to wire my light switches,and can I use 10 gauge wire on a 10 amp breaker? For a light fixture

Normally lighting circuits have a 15 amp breaker for protection and wired with 14 gauge wire. 14 gauge wire is good for 15 amps. 12 gauge wire is good for 20 amps. 10 gauge wire is good for 30 amps. So you can use 12 gauge wire, if you alrady have it available, but if you are going to go out and buy it, you can save some money by buing #14 wire. You can always go oversize with the WIRE just never undersized with the wire. Circuit breakerprotection is prescribed by the NEC. 15 amps for lighting and 20 amps for wall outlet power. I don't know where you even found a 10 amp breaker. ---------------------------------------... WOW! XTX has no clue what the National Electrical Code even says about this! Disregard his answer! It will get you into trouble!

Q:I removed a dishwasher and now the wires are exposed. I turned off the circuit to that outlet. I am planning on waiting a while to replace the dishwasher. I want to turn the circuit back on so I can use the other outlets, but don't want to leave the wires exposed. Any ideas?

wire nuts that can hold 1 .. 14awg wire or a bit smaller... twist one on each individual wire and give it a little tug, it sould not come out, then wrap some electrical tape around each of them

Q:i have a 2002 pontiac sunfire where is my ground wire located? what does it look like?

There is ground wire that connects the battery's negatime post to the frame of the car and that is it. If you are looking for a ground wire to connect something to eg. an amp, just connect the ground from the electronic device to the frame of your car via a bolt that goes in to your cars chassis/frame.
