A cooktop is wired in accordance with standard electrical practices - by a qualified electrician. Attempting to do this on your own can result is the unit not working, the unit being damaged, an electrical fire in the location, or injury or death to the "would-be" electrician. These hazards cannot be stated strongly enough. The basic philosophy of the technical minds here and of WikiAnswers in general is that if you have to have something like this explained to you, it is not something you should be attempting. Wiring a cooktop isn't as challenging as something like neurosurgery, but people have died during both procedures. Please contact a qualified electrician for assistance. At least get an estimate, and ask for some detail of the costs to get a better idea of what is involved. Let's be clear: you are not being called stupid or anything else. You do have knowledge and skills, but not the knowledge and skill set (nor the experience) needed for this job. Instead, you are being asked to get professional assistance for a project that can have lethal consequences for the shortcomings of the individual undertaking it if that person is not "qualified" to do it.
There are zero amps in a watt. I = W/E. W = A x V.
It depends on how many volts there are. Since watts is amps times volts, amps is watts divided by volts. If you had a 120V circuit with 1 watt, there would be 1/120, or 0.00833 amps flowing in that circuit
Note: This is the resistive answer, with a power factor of 1. For reactive loads, things change, but the basic question is answered.
Wire a three-way switch One light controlled by two switches- similar to a hall ligt. SPDT switches?
To wire a three-way switch with SPDT switches for one light controlled by two switches, you will need to connect the common terminal of one switch to the hot wire coming from the power source, connect the common terminal of the other switch to the light fixture, and connect the two remaining terminals of the switches together with one wire. This configuration allows either switch to control the light. Be sure to follow proper wiring techniques and safety precautions.
A container or devise that holds something
A "receptacle" in electrical jargon is what most people call an outlet. The above answer is correct in that it gets its name from the fact it holds something -- a plug.
In pure electrical jargon, in the United States, an "outlet" is the box that contains a switch or receptacle or from which a fixture is wired. So when you read the NEC, an outlet is the box, not the device or equipment contained in the box.
General Speaking White is the Common or Ground Wire.
Perhaps if you searched online for the maker of the braking system you would find them and could call and ask if they are still in business that is.
Hope This Helps.
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
How do you find out if a wire is grounding out?
To determine if a wire is grounding out, use a multimeter set to test for continuity or a short circuit. Place one probe on the wire you suspect is grounding out and the other on a known ground point. If the multimeter beeps or shows a reading of zero ohms, the wire is grounding out.
What gauge wire should you use for wiring a dock - in conduit - 350 ft at 220 volts?
That depends on the load. In other words how many amps does your load utilize or how many watts? Either figure will work.
<<>>
Wire size is based on amperage. The higher the load amperage the larger the wire size has to be. In this case also, the wire has to be increased in size to over come the voltage drop for the distance to the load. To receive an answer restate the question with the load amperage or wattage.
Can you tie new dryer wire into old wire?
Yes, as long as the splice is made in a junction box that can have a cover attached to it and it must be accessable. This means its not to be covered with drywall. The wire must also be of the correct size and conductor count. For a dryer it is a 3 conductor #10 wire. The breaker size at the breaker panel is a two pole 30 amp.
What happens to a balloon on a hot day and what might happen if it gets to hot?
When air is heated, its volume increases. If you fill a balloon with comparably cold air and then let it touch hotter air, the air inside will expand and thereby increase the pressure on the balloon membrane. If this pressure gets too strong, the balloon might pop.
Alchemy is not supported by scientific evidence and is considered a pseudoscience. The concept of transmuting base metals into gold or creating an elixir of immortality has never been achieved. Today, alchemy is typically viewed as a historical practice that laid the groundwork for modern chemistry.
No, the black wire is typically used as the hot wire in a standard electrical circuit in North America. The neutral wire is usually white. It is important to always verify the proper wiring colors and configurations, as they can vary by region and application.
That green wire is a Ground or Earthing wire which must be connected securely to the metal casing of the Dryer.
Its purpose is to protect users of the dryer from electrocution if something ever goes wrong inside the dryer that would cause the casing to be made electrically "hot" or "live" if such a protective Ground or Earthing wire was not installed. It works by making sure the circuit breakers shut off the power. Another reason is to help prevent house fires.
For more information about earthing wires and dryer circuits please refer to the Related questions shown below. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.
In USA do you have to connect a ground wire to a GFCI outlet for it to work properly?
No. A GFCI receptacle does NOT require a ground wire to operate properly or to meet code. The GFCI device measures current in the hot and neutral wires and makes sure they match. The device trips when the currents do not match, indicating that the current is not following the proper path (ground fault). Actually, replacing an old 2 wire ungrounded receptacle with a GFCI is a code approved way to upgrade to 3 wire grounded receptacles. The GFCI and any outlet(s) protected by it are allowed to be 3 wire receptacles. ----
If you do not understand the work well enough to accomplish it yourself properly and safely, don't try it. Consult a professional electrician, as they are proficient enough to do it properly and safely. When working on electrical circuits and equipment, make sure to de-energize the circuit you will be working on. Then test the circuit with a definitive means to make sure it is off (multimeter with metal tipped leads, voltage tester with metal tipped leads, etc., not a non-contact tester, which is non-definitive.)
A 12V outlet is a power socket found in vehicles that provides 12 volts of direct current (DC) power. It is commonly used to plug in and charge electronic devices or power accessories such as car chargers, air compressors, and portable refrigerators.
Can a 125 amp breaker box replace a 100 amp breaker box?
Sure but go for a 200 amp box if you are certain your incoming power supply cable from the street can support it. You should always check with your local electric power company before you upgrade any main supply panel or breakers.

How do you calculate the cable size for a run of 30 meters?
to calculate the cable size of a run of 30 meters long
you first will have to know the current of the appliance
use the voltage drop formula
V d = (mVxIxL)/1000
once the voltage drop is less than 2.5% of the nominal voltage,
the cable should be upsize.
Do you have to have an electrical technicians license to install meter pan and breaker pan?
It depends on your local regulations and jurisdiction. In some areas, a license may be required to install meter and breaker panels due to safety concerns and regulations. It is best to check with your local building department or electrical authority to determine the specific requirements in your area.
You have two options, one is a complete service change. The average house service these days is 200 amps 42 circuits. The second option is to install a sub panel off the existing service. Depending on how many circuits you need will govern the size the sub panel. Here is where it gets tricky. Two side by side single pole breakers or one two pole breaker will have to be removed from the original service panel and replaced with a new two pole breaker. The size of this breaker will be governed by the total load of the new sub panel. The wire from the new sub panel to the two pole breaker is also governed by the load of the sub panel. As an electrician I would recommend that you not do it yourself but get a qualified electrician to do it for you. He would (should) take a permit out for the job and get it inspected.
What if the new light fixture has 2 black wires and no white wire?
If the new light fixture has 2 black wires and no white wire, it likely means that the fixture is designed to be connected to a circuit where the white wire has been designated as the hot wire instead of the black wire. Make sure to double check the wiring and consult a professional if you are unsure.
Is 124 volts TOO HIGH for household wall outlet in USA?
Normal voltage for 120volt outlets is 110v to 130v. It would vary depending on the length and size of the wire to the nearest power company transformer, and the different voltage terminals on the transformer that the power company connects.
How do you add more breakers to a main supply panel?
New breakers can be purchased separately, and simply snapped into place in the modern breaker panels. Turn power off to panel before removing breaker panel plate. If you do not know what you're doing, save your life and hire an electrician to do it.
Note: The latest types of Ground Fault Circuit Interruptor (GFCI) are also called Residual Current Devices (RCDs).
"Can you put a GFCI into a circuit with a GFCI?" is probably the same question as "What if two GFCI are in series in a circuit?" and the answer is that one GFCI will most likely trip earlier than the other to break the circuit. Which one will trip first depends on the actual difference in sensitivity between the two GFCIs. Leakage currents are measured in mA (1 mA = 1 thousandth of an Ampere) and GFCIs are designed to trip at a certain leakage current with a tolerance of say + or - 3%. So if the basic trip current was 20 milliamps one GFCI might trip at 19.4 mA and the other at 20.6 mA and they would both be within the design specification. The one that trips at 19.4 mA would be expected to trip first. <><><> This question requires answering by a VERY knowledgeable electrician, or an electrical engineer. I am neither, but until the right answer comes along, I will attempt to provide some information which hopefully will allow a better understanding of the issues involved. A GFCI [ground fault circuit interrupter] is much different from, although similar to, a circuit breaker. The DIFFERENCE is WHAT they are designed to detect and react to. The purpose of a fuse or circuit breaker is to detect excess or MASSIVE current flow [ie. a SHORT CIRCUIT, a direct short to ground], and then very quickly turn off the electrical current to the circuit, in order TO PREVENT a FIRE. This is the only thing the breaker is designed and intended to do. This limited capability will not prevent a person from being electrocuted when a fault occurs within an electrical device, if the current flow happens to be low. Voltage and current faults which can kill a person usually will not be detected by a circuit breaker. A ground fault circuit interrupter [GFCI], on the other hand, is designed to, and will, detect those low level currents which can kill a person, BUT which are not great enough to trip a breaker. When a GFCI detects potentially dangerous current it, like a breaker, trips in order to open the circuit. Now as to WHY, when you placed two GFCIs in series [one in the breaker panel feeding one in an electrical receptacle], the first GFCI tripped when the second GFCI is "tested." When you press the TEST BUTTON on a GFCI it puts a high resistance load on the circuit, which simulates a "small" ground fault, and I think both GFCIs "see" the same fault and react as designed and intended. Again, a true professional should "bless" my comments, but I think that there is no danger or hazard in placing two GFCIs in series. On the contrary, I think there is redundant capability in the pairing, with the first GFCI functioning with, and as a backup to, the second. I suggest you contact your local electrial inspection department regarding what the code(s) say about this issue, and also call the tech support people at the 800 number on the packaging for the GFCIs. Another source of information is a local electrical engineer, if you know someone who can help you make contact. Until a more informed answer comes along, I hope this helps you to understand the issues involved. <><><>

Will number 8 gas rated wire feed a 60 amp garage sub panel installed in USA?
No, a number 8 gas rated wire is not sufficient to feed a 60 amp garage sub panel in the USA. You would typically need a minimum of a number 6 wire for a 60 amp circuit to ensure it meets the National Electrical Code (NEC) requirements for safety and capacity. It is always recommended to consult a licensed electrician for proper installation of electrical wiring.
You're talking about two different measurements. Voltage is not equal to current (amps) nor is there any correlation between the two.
If you know the amount of watts the device uses, you can divide the watts consumed, by the voltage to get a rough estimate of the amps being drawn.
For example, a 1000 watt microwave running at 120 V will draw 8.3 amps.
AnswerThe formula is U = R*I, U (voltage in volts), I (flowrate in ampère), and as you see... you first need to know what R (resistance in ohm) you have... the you calculate U/R = I, that's all. AnswerThere are no volts in amperes. They measure different quantities. Your question is like asking, "How many kilometres are there in 2.5 kilograms?" In other words, it is nonesense!
