Q:True or False?Branch wiring from a 200A - 3 phase 4 wire panelboard.WIRE #PHASES 1 --- PHASE A 2 --- PHASE B 3 --- PHASE C 4 --- NEUTRAL - WHITE WIRE 5 --- PHASE A 6 --- PHASE B 7 --- PHASE C 8 --- NEUTRAL 9 --- GROUNDTOTAL OF 9 WIRES GOING TO SIX (6) 20A 120V CIRCUITS

That's true. 9 wires may go to 6 circuits. Each circuit has one phase so 1,2,3,5,6,7 are the six phases going to six circuits. For two pair of three phases (pair one 1,2,3)(pair two 5,6,7) there are two neutral wires and one common earth wire. that is total nine wires. there is nothing wrong in it.

Q:I understand that in a plug you have the earth wire, live wire and neutral wire. But what is the individual job of these wires?? I know how to wire a plug, i just want to know the individual job of each wire. This is not homework, this is something iam teaching myself.Thanks.

The typical U.S. power distribution system has two hot wires coming into your electric panel, plus a neutral wire. The neutral wire is grounded to earth ground, as is the protective green earth wire. An outlet, carrying 110 volts from one of the hot wires (black), supplies current for the load and it flows back to the transformer on the pole normally via the neutral (white) wire to the center transformer (grounded) tap. The green protective wire does nothing in normal operation. However, should the appliance have a metal outer skin, and the machine develops a short, energizing the outer skin, it will flow through the green ground wire back to the transformer rather than through you and back to the transformer.

Q:I don't like wiring nuts because I always feel like it's not a solid connection, like it could come out.

This Site Might Help You. RE: Is there an alternative to wiring nuts? I don't like wiring nuts because I always feel like it's not a solid connection, like it could come out.

Q:What method can be used to detect residual impurities and metal particles on the wire surface?

Therefore, the removal of metal surface impurities and removal of metal surface oxides, the two are different.

Q:I have this ipod cord in my car to play music off of, and at first it started cutting out. I would move the wire in a specific spot to a position to where it would work. Then eventually it just stopped working all together, so im assuming the wires inside have been damaged. Now as i said before in a specific spot so im pretty positive i know where it is broken at, but ive never actually spliced a wire, or soldered before. This is where i need help. What tools and materials will i need to fix the wire? Also, how would i fix it? Thanks for the help in advance!

The wires in those little patch cords and headphones and stuff are often very fine and hard to splice or solder. You could get you some wire cutters and wire strippers and a soldering iron and some electrical tape or shrink wrap and go at it, but it would probably be just as well to get another cord.

Q:Or can stranded wire of the same gauge be subsitituted for solid wire without any consequences? The reason I ask is because its for a massive 4kJ capacitor discharge circuit, and I need all the energy delivered to the power coils im using, cant afford to have much leakage inductance.

Stranded wires have slightly higher inductance than solid wires, but this is noticable only on transmission lines and larger conductors. if you are only using a short conductor, i don't think the inductance of the wire will affect the system, unless the wire is coiled.

Q:i have a 00 gmc yukon and tried installing my cd deck. i pulled off the original harness from the stock deck radio and now its just all wires (its my first so i didnt know), i connect the alpine deck wires and tried to connect them all together. i had a few figure out, except a small noise coming from my stock tweeters every time i step on the pedal. then my speed odometer sensor was going with the bass of my subs... whats wrong? can someone find me a chart of what color wires supposed to go where? thanks for your help

do now no longer combine the speaker outputs out of your head unit. you could harm the final unit this type. you at the instant are no longer harming something via using working a a hundred-watt speaker on a lots cut back powered amplifier (and you will now no longer inevitably boost the sound intense high quality via using switching to a speaker with a cut back skill score). The a hundred-watt score is only the optimal skill it truly is stated for this speaker; it does now no longer propose that it demands that lots skill. in case you pick for extra advantageous skill than your CD deck substances, you will might prefer to function an outdoors amplifier.

Q:which guage power wire will handle 100 amps

4 or 2 gauge wire running 10 to 20 feet for 100 amps.

Q:let me start off with I am not an electrician I just do basic stuff for side work I came in the project at the end. The lady wanted me to wire in 6 receptacles, a light switch and light fixture all on one circuit. everything is good except for the receptacle at the start of the circuit it has the lead/ hot coming in the power to the other receptacles going out and the power to the light going out (3 groups, 9 wires total). normally I would have used a junction box but I didn't pull the wire. How can I wire this. Would a 15 amp receptacle work?

A 15 Amp receptacle will work, of course, but the receptacle box is most likely already overfilled. So in order to keep the wire count down, your best way to go is to buy a receptacle that uses screw down connector tabs. (NOT the kind that you have to put the wire under the screw, but the kind that you insert the wire into the back and then turn the screw down to clamp onto it!) The receptacle is a little more money but it would be worth the expense to make this hook up work. Hot wire (Black): Connect all three black wires to the back of the receptacle on the brass colored screws. Common wire (White): Connect all three white wires to the back of the receptacle on the silver colored screw. Ground: make a short pigtail of bare copper wire (about 6 or 7 inches long). Then connect the pigtail to the other 3 bare copper ground wires using a wire nut. Then connect the other end of the pigtail to the grounding connection of the receptacle. MAKE SURE THE POWER IS OFF WHEN YOU DO ALL OF THIS SO THAT YOU CAN LIVE TO TELL THE TALE! :-)

Q:When making pc boards with microcontrollers, oscillators, etc.. What is the right kind of wiring to use? Specifically:What material (e.g. copper)?What thickness?What brand?Where to buy?What's the difference between the stiff wire and easily bendable wire?Thanks.

I don't mean to piggyback on his question but I'm also doing a project. Making a solar phone charger... My first project really but I have one solar panel 5V max output, but when soldered only gives out 2.8... Sending it to a mini buck booster but that needs at least 2.6 to work. I am just using simple stranded speaker wire, and admittedly the soldering skill needs work. But what kind of wire would I use
