Another name for average voltage is the RMS (Root Mean Square). This is a voltage derived from the peak to peak voltage multiplied by .707. If the peak to peak voltage is 170 volts then the average voltage (RMS) would be 170 x .707 = 120 volts.
How far can you run a 12 gauge electrical wire?
The maximum distance a 12 gauge electrical wire can run depends on the voltage and amperage of the circuit it is serving. In a typical residential circuit with 120 volts and 20 amperes, a 12 gauge wire can run up to 60 feet before voltage drop and overheating become concerns. It is always best to consult local electrical codes and standards for specific guidance on wire length limitations.
How many receptacles can be put on one circuit?
In North America there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit. ( This is not found in the National Electrical Code)

Generally each duplex outlet may count for 180VA. For a 15A circuit = 8 duplex max. For a 20A circuit = 10 max. This is in the Wiring Code, by the way. (This only applies to non-residential applications)
In some states the 3 amp per outlet is still being used. For this case, 6 outlets max. ( What States?)
In dwelling units there is no requirement for a maximum number of outlets on a circuit. The circuit could serve a single room of 500 sq. ft. and serve as many outlets you wanted including the lighting loads. (3 watts per sq. ft X 500 sq. ft.) This is the minimum requirement of the code and not necessarily good wiring practice.

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.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What is the fuse size for a 200 watt McKinley amp?
The Full load current of that amp is approx. 17A, but you base you fuse size between the Full load current of your load and the current carrying capacity of the supply cable, if the size or the CCC of the cable is unknown, I would recommend sticking as close to the FLC as possible
Wire size for 500 Amp service?
For a 500 Amp service, the recommended wire size would typically be 4/0 AWG copper or 300 kcmil aluminum. However, it is always best to consult with a qualified electrician to ensure the correct wire size is used based on the specific installation requirements and local electrical codes.
How many amps equal to 1 watt?
That depends on the voltage. One amp flowing at a potential of 1 volt produces 1 watt of power (equal to an energy consumption of 1 joule per second). 4 amps flowing at a voltage of 250 volts produces a kilowatt of power. This would be enough to satisfy the individual needs of a lot of the electrical equipment around the house.
How do you megger test continuity on a basic lighting circuit city and guilds level 2?
You don't megger test continuity. You test for that with a continuity meter or ohmmeter. "Meggers", as they're often called, produce high voltages to test the integrity of a conductor's insulation.
How do you install 120v outdoor lighting?
The same way as indoor lighting, but your fixtures must be rated for use in wet locations. This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself, or call a professional electrician. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.

How many amps is 4 wire good for?
According to the 2008 NEC Code Book a #4 AWG Copper wire is rated at 95 Amps @ 90C (194 F), 85 Amps @ 75C (167 F), and 70 Amps @ 60C (140 F). These allowable amperage ratings are based on the wires type of insullation.
What size wire for a 240 volt 8800 watt stove?
8800w/240v = 36.6 Amps Since at some point (Thanksgiving, etc) you may use this range for more than 3 hours straight, your wire size must be calculated at 125 percent of that number: 36.6A * 1.25 = 45.75 (rounded to 46) Amps Using the NEC table 310.16, 75 degree column, the smallest copper wire that can carry 46 amps is #8 AWG. If you use aluminum the smallest is #6 AWG.
Yes, you can use lower amperage outlets - the problem would come if you were trying to run a 20 amp appliance on a 15 amp circuit or plug a 20 amp appliance into a 15 amp outlet. It would be better, though, as some kitchen appliances could exceed 15 amps (toaster ovens, some coffee makers, electric griddles, etc.) could try to draw more than the 15 amps your outlets are designed for. Perhaps you could get some 20 amp outlets and use those 15's in a hallway or something less likely to have high amperage draw.
What is the temperature rating of thhn?
THHN wire is moisture resistant thermoplastic allowed for use in dry and wet locations. Maximum temperature is 60 C or 140 F. Being thermoplastic it should not be handled below 0 C as cracking of the insulation could easily occur.
How do you wire a ceiling fan?
A few months I had the same problem, I wanted to install my ceiling fan too.
I didn't know how to do this, after searching the Internet I found this website:

In a 60 watt light bulb how much energy is converted into light?
Roughly 90% of all incandescent bulbs energy is converted to heat. Another portion is given off in non visible light. The rest helps you read. High Efficency bulbs provide roughlythe same levels of visible light using 17 watts. They have other serious issues, including mercury inside the bulb and overall shorter lives, but use less power.
In a 60 watt light bulb how much energy is converted into heat?
In a 60 watt light bulb, most of the energy (around 90-95%) is converted into heat, while the remaining 5-10% is converted into visible light. This inefficiency is why traditional incandescent bulbs are being replaced by more energy-efficient options like LED bulbs.
How do you install a ceiling pull switch?
How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact location of the ceiling pull switch you wish to install.
So:
a) Go to your local library or bookstore to find some books about electrical wiring and appliances and how to install them safely.
b) Find out about your local Wiring Codes and Regulations.

Can you show me a diagram for connecting a 240v generator to the breaker panel in a home?
A generator, whether portable or permanently installed, requires a transfer switch between it and your panel. The transfer switch is there to keep two power sources from being turned on at the same time (such as the generator and your incoming service). If you didn't have a transfer switch and both sources were connected to the panel at the same time, when the power grid came back up it would be connected to the generator, and that would cause fire and explosion. Also, when the grid was out and a lineman was trying to fix it, your generator would be 'backfeeding' power to the grid, either keeping linemen from working on it or worse, coming online after a worker has started repairing it. For these reasons a generator and transfer switch should be installed by a licensed electrician. If you want to do it yourself anyway, buy a transfer switch. It will come with installation instructions to put it between your generator and panel. DON'T put a 50 amp 'multipurpose receptacle' onto your panel and backfeed the panel. It's neither legal nor safe, and it can get people killed.

180. well that is a partial answer and is only true if those 1.8 amps are pushed through at 100 volts.
Watts= Amps times Volts
An amp (Full name=Ampere) is 6.241 × 1018 electrons passing a point in a circuit in one second. It doesn't matter what the voltage is, an amp is as stated above.
AT 12 volts, watts=1.8*12=21.6
At 120 volts, watts=1.8*120=216
At 1200 volts, watts=1.8*1200=2160
Without knowing the voltage, one cannot determine the wattage.
There are some small discrepancies between Alternating Current (AC) Direct Current (DC). With DC, the formula can be considered correct. With AC, it is an average Wattage. Why, you ask. Because AC voltage Is kind of an average. As the voltage alternates between positive and negative, it really goes a bit higher than 120 volts. In fact it goes 1.414... times 120 volts or as high as and as low as ±169.68 volts. (1.414... is a rough approximation of the square root of 2.) This formula, Peak Voltage= VoltageAC times Square root of 2, is called the "root mean square."
You can look all these terms up by searching for them on the internet.
Ampere (Amp) (A)
Volts (V)
Watts (W)
Alternating Current (AC)
Direct Current (DC)
Root Mean Square (RMS)
To summarize the formula:
W= V * A = Watts
V= W / A = Volts
A= W / V = Amps
Notice: you must know two of the relevant values.
<<>>
1.8 amps is equal ot zero watts. Watts is the product of amps times volts. To answer this question a voltage value must be stated.
As a minimum you need to run #10-2 AWG or 10-3AWG. (The extra wire is a Neutral for 110 Volts). You may want to use #8 AWG to make up for voltage drop if you are using something power intensive and it is a long cable run. <><><> You should also install a Ground wire and a GFCI to help to protect persons using the kiln from electrocution.
Also ensure the correctly-sized circuit breakers are installed to protect the new circuit from catching on fire if there is a short circuit or some other type of current overload fault condition develops. <><><>

In most cases it doesn't matter, but some appliances like a light dimmer will not work correctly otherwise. If it is a electronic device it will have a capacitor between signal ground and neutral. Faulty wiring will make it possible to get small (non lethal) shocks by touching earth and signal ground or introduce hum in audio devices. So, important no, but wise.
Does a 30 amp camper plug have 220 volts?
No, a 30 amp shore power plug is strictly 120volts. A 50 amp shore power plug is technically a 220v system, however the camper uses the two 120v wires in the cord separately. There are no 220v appliances in RV's today.
Can a silicon solar cell produce electricity in large quantity?
Yes, silicon solar cells can produce electricity in large quantities when they are arranged in solar panels and exposed to sunlight. Solar panels can be grouped together to form solar arrays, which can generate significant amounts of electricity for both residential and commercial applications.
The size of the ground wire for a circuit is typically based on the size of the circuit breaker protecting that circuit. For a 200 amp circuit breaker, the recommended ground wire size is 4/0 AWG (American Wire Gauge) copper wire. This wire size helps ensure that the ground wire can safely carry any fault currents that may occur in the electrical system.
Adding a 220v 20 Amp AC circuit to an existing breaker box?
By asking this question you are probably not quite ready to take on this particular task. You may or may not get lucky and receive some information in an answer here! If you hope to get enough information on this site to be able to do this job properly and safely, please do not rely on getting accurate information about such a potentially dangerous subject. Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you put just one wire in the wrong place you risk being killed by electrocution or you could even start a house fire.
How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact locations of some of the outlets you wish to install. If they are anywhere subject to water splashes or spray - such as in any room supplied with running water pipes, like a kitchen, bathroom, shower room, etc., or in a pool-side area - in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician. If you don't want to go to your local library or bookstore - to find and read some books about electrical wiring and appliances and how to install them safely, and to find out about your local Wiring Codes and Regulations - then the best advice anyone should give to you is to call a licensed electrician either to do the job for you or to advise you what you may be allowed to do yourself.

Is it ok to wire a 240 Volt air conditioning unit with 10-2 gauge wire?
<><><>
That answer assumes the A/C is to be installed in a residential installation, because the service voltage is 240.
The length of wire-run should also be factored-in when deciding the correct wire size.
To get the right answers refer to the Wiring Codes or Regulations for your locality. (Town/State.)
