Electrical Wiring

first i need to know which model i have some or you can purchase a clymers manual #m420

Automotive : negative ( ground ) side

Household : common ( hot ) side

See related links below for answer.This link should be very helpful.

The batteries would get very hot, the cables might be set on fire and the metal screen could get so hot it might melt. This experiment is likely to be dangerous so don't do it! There is no reason for anyone to want to trash a good pair of jumper cables and a metal screen this way...

Go to the library and get a chiltons repair manual for your year car.

The CDI diagram at the bottom is your best bet for the essentials; most Chinese bikes follow those colors.

The voltage to a split receptacle is delivered by a 3 conductor # 14 cable. In the service panel the wire will be connected to a 2 pole 15 amp breaker. The white wire will connect to the silver coloured screw on the receptacle. On the brass side screws you will see a tie bar between the upper and lower screws. Using needle nose pliers, remove the tie bar by wiggling it back and forth until it breaks out. (Be sure the terminal screws are tight, or you might damage the tab. The tab is made to break easily with a few wiggles). Now you are left with two separated brass screws. Install the red coloured wire under one screw and the black coloured wire under the other. Connect the bare ground wire under the green screw. Install back into the wall, replace the cover plate. If the tie bar is not removed the breaker will trip due to a short circuit across the 240 volt legs of the service panel. Code states that the breaker feeding split receptacles must shut off both hot wires at the same time. NO connection to two single pole breakers without a common tie bar to shut the breakers off together.

Farm tractors and some trucks and industrial engines can have a PTO or Power-Take-Off shaft that is used to power attachments such as sprayers, hydraulic pumps and, well, generators. The PTO is low speed, so a PTO generator usually has a gearbox to step the speed up to the RPM needed to turn a generator. PTO's are pretty standardized and use a short driveshaft to couple the tractors PTO to the attachment. PTO generators are used where remote power is needed and a PTO-equipped vehicle is available. It saves having to buy and maintain another engine.

I would buy a Haynes or Chiltons manual for the car. I have a Haynes for my 72 Duster, and it has all the wiring diagrams. Also, an absolute wealth of information on every other component of the car. Very useful.

i need a wiring diagram for a 2004 4 x 4 rancher ATV

yes,the only difference is the carb and the intake manifold.both engines have the same mounting]

The GMA series of fuse is a fast acting glass tube fuse. The dimensions are 5 X 20 mm. This series of fuse's amperage span is from 63 mA right up to 8 amps. I would suggest that your fuse is rated at 250 mA or (1/4 of an amp) with a 250 volt rating.

I got a Haynes repair manual for jeeps .It was a good help for me

To know how much current a load is drawing, you must know Ohm's Law. You must also need to know what the voltage is and the resistance of the load.

IMPROVED ANSWER 1 / DATE:25.05.10:

Before discussing this question, I would like to share few things regarding the information, I got from the webs. When I search the different kind of answers for this question, I finally satisfied from sir Kevin Boone's (UK) explanation. I can share those information.

Topic is selection of cable, selection of protection device for a circuit etc.

Several steps are there, we can see one by one:

Step 1: Find the nominal current for the given load. For eg., if you choose 5kw load, the nominal current for such load is 5000/230 = 21.7 ~ 22A.

Step 2: From the nominal current, we can choose a MCB of rating 30A. (should be greater than the nominal current, so it could be next available MCB)

Step 3: Selection of cable should withstand the nominal current. In which one should keep in mind that we should consider the type of installation of the cable. Because the rating of current for the cable can be vary according to the installation. For eg., installing the cable inside the wall or trunk or any other strong insulation or through the open air. The cable which installed open in the air can withstand more current when compare to the cable which installed inside the wall. So for simplicity, we can assume the cable is installed inside the wall (generally this kind of installation is followed by most of the engineers). When I go through the manufacturer table 4mm 2 cable installed inside the wall can carry current up-to 25A. So it is suitable for our load.

Step 4: Now for our 5kw load, 30A MCB & 4mm 2 size cable are selected. But keep in mind the surrounding temperature should be consider. Since the current rating for the cable could be vary to the temperature. Normally the installation is designed for 35 degree to 40 degree Celsius. Let us consider the ambient temperature is 35 degree. So under 35 degree Celsius the 4mm 2 cable's correction factor is 0.94 (IEE wiring Regulations 2001). So the current rating of the cable under 35 degree Celsius is 25 * 0.94 = 23.5A. It is satisfied to withstand for our 5kw load.

Step 5: Voltage drop should be taken in account. Normally voltage drop could be up-to 9.2 V (4% from the rated voltage) is allowed. Let us assume from the distribution board to the load, the total cable length is 20m. From IEE wiring Regulation table 4D2B: the resistance of line & neutral per meter is 0.011 ohms. So for 20m length it will be 0.011 * 20 = 0.22 ohms. The voltage drop is 22A * 0.22 ohms = 4.84V. So it is well suited under 9.2V. Hence our selection is correct.

CONCLUSION: For our selected load 5kw, 4mm 2 cable with 30A MCB is the good choice.

It would work but it would probably run 20 per cent faster, so if that is not a problem it's OK. But if the load is a fan, the motor might not be able to supply the extra mechanical power at the extra speed, so it would run but it would overheat.

Measure AC voltage with multimeter. It is easiest way to check how big ripple is.

There is no way to 'calculate' value.

Generally speaking, the rated power of any light fitting ('luminaire'), including a table lamp, is determined by the enclosure, shade, or reflector, rather than its socket. What it comes down to is (a) whether the rate of heat transfer away from the lamp is sufficient to prevent the luminaire from overheating, and (b) whether the reflector/shade can withstand the resulting temperature.

You will need a phase converter. Avaliable at an industrial supply company like granger supply

Yes. Where conductors are used at radio frequencies, a 'skin effect' is thought to take place, and often the conductors are plated with silver, which has a higher conductivity than copper.

Another more common example is in electronic plugs and sockets, where the pins are often plated with gold, so as to minimize contact resistance. Gold is unreactive, and this gold plating offers little hold for corrosion that would otherwise interfere with the passage of electrical signals.

A third example would be in high voltage transmission lines, where a steel core is used for strength, and this is given a wrapping of aluminum sheathing. This is not true plating, but gives higher conductivity for a given span which would otherwise be limited by the breaking strain if aluminum alone. .

It depends somewhat on context. A dc circuit consists of of a flow of current to the load and back to the source.

This is often called the loop. The loop resistance would be the total resistance measured in ohms.

In most power circuits the above would hold true in an ac circuit as well.

A three-phase transformer bank is often used in power stations because it is easier to construct and transport very large single-phase transformers, compared with constructing and transforming an equivalent-capacity three-phase transformer.

A electrical light curtain is a safety device that protects people from getting too close to operational moving machinery. If a person crosses over a set-point threshold an alarm will be set off due to breaking a beam of light. This type of safety precaution is preferred over mechanical barriers that have to be removed every time work has to be done on the machinery protected by the light curtain. It is very closely related to motion detectors that are used in homes for security.
