50 Hertz Residential Electricity

Parent Category: Electrical Wiring
All of Europe and most of mainland Asia and Africa use 50Hz frequency for their residential electrical needs. Some countries use 50Hz, as they found it economical to maintain and operate power-generating equipment at this frequency.
Answer for UK and European electrical system.    Guide to connecting a new socket outlet to the power cables of a  ring main, and fixing it to the back box or pattress in the wall.  Depending upon where in the circuit you are fitting the socket you  may have one, two or three sets of...
Australia uses 240V, while North America uses 110V, so in order for  your appliances to work you will need to get an adapter.
You don't. It is the responsibility of the utility company that you purchase the power from. Request that they come out and check the voltage fluctuations. If you are on the end of a power line they can adjust the taps on the transformer. If not at least you are notifying them that there might be a...
The fixture construction has nothing to do with the amount ofenergy that the fixture uses. It is the lamp in the fixture thatdraws the amperage. This amperage times the fixtures voltage iswhat gives you the fixtures wattage. W = A x V. Watts = Amps xVolts.
because of the choke,as a result of eddy currents in the choke whick has lost its lamination
Without knowing what device the blue and brown wires are on, an answer can not be given.
Easy: make sure both ends of the cable are completely disconnected. Go to one end of the cable, twist 2 cores together for instance brown and blue. Now go to the other end of you cable and test the continuity between the brown and the blue cables. This will verify both of these cables are continuous...
You will have to use a step down transformer to do this. Voltage to earth measures 277 vac on a 480 vac wye system.
That probably is decided by the carrier.
The answer depends on the electrical wiring standards of the country you are asking about. Answer for USA, Canada and countries using similar 60Hz household electricity supplies: the ground or "earth" cable is just bare wire or has green insulation. Answer for countries in Europe and in other...
The cable expands, so the lines may be observed to droop on excessively hot days. Conversly, the line tension has to be designed so they don't get too taught on cold days
MW is megawatts which is a million watts. KW is 1000 watts. Can you do the math or should I tell you it is 1000KW
  == Answer ==     For the USA its 240V (120V on each line/phase).
If this is a residential system there are likely two hot wires, black and red. White is neutral and there will be 115 volts between white and either hot. Ground is typically green or a bare wire. <><><> If this question is really asking about a 50 Hz service - as its Category has...
I have no idea what a normal household battery is. Generally you would have to match the current and voltage of the car battery and then you have the issue of how long the battery can sustain the current, or ampere hours.
Red - active, (commonly known as your live cable) Black - Neutral Green - Earth
As obvious as it may seem, so that they connect power stations to load centres which might be hundreds of kilometres away!
Elecb is voltage operated device where as RCCB is current operateddevice. RCCB is the preferred one. ELCB is outdated.
You can use a voltage meter. A fully charged battery of 12v should read 12.6v with negative cable disconnected, and all accessories off. It should not fall below 12.4v when fully charged. This is the easiest way to check.
This information should be in the documentation that came with your light but...Since most of the energy used in an LED is given out as light (as opposed to an incandescent bulb, which uses most of it's energy as heat) it is probably OK to insulate above it. However the transformer pack may still...
Would that be the smallest pin. To answer this question the specifications of the plug will be needed.
m means milli, as in 1/1000A means Amps50mA is = 0.050 AmpsAmps is the amount of current passing through a device.

== Basic Answer ==  Good question!   In US residential wiring, you have 3 wires feeding your home off the transformer: two hots and neutral. The transformer is a 240V center tapped transformer. The neutral is the center tap.   Well, that's all fine and good, but your probably asking "what...
most places about 120 a month for electric, 50 to 70 for gas
240 mm conductor can carry 425 Amp. current in each core
For the electricity companies the advantages are : - Transformers dont damage (Transformers are most efficient at full load) - Constant use of electricity meaning that theres no need for storing electricity (even though its near impossible to store AC) For the customer the advantages are: -...
if the appliance is manufactured after 1920 it will have a nameplate somewhere near the power connection. this nameplate SHALL have the amperage and voltage required. the fuses in a house are sized so as to not set the house wiring on fire. that being said water heater nameplate 28A 240V...
1 terrawatt is equal to 1 000 000 000 000 watts this is given by terra being x10 to the power of 12 and if your familiar with computers: 1 terrabyte = 1 000 gigabytes = 1 000 000 megabytes = 1 000 000 000 kilobytes = 1 000 000 000 000 bytes so the same goes for watts.
A meter box is the metal box mounted to the external wall of a homethat houses the meters, circuit breakers etc.
AS PER THUMB RULE THE CURRENT CARRYING CAPACITY OF WIRE IS 4 TIMES OF ITS CROSSECTIONAL AREA OF WIRE i.e. 10 sq.mm wire carrying maximum current 40 amp , 16 sq.mm carrying maximum current 64 amp , now amp convert in watt by multiplying by volt i.e. 240 16 sq.mm carrying max load 64x240= 15360 watt
The ground/earth pin is longer because: It needs to be the first wire connected when connecting to a socket outlet and it needs to be the last one to break the outlets connection if that makes any sense. The ground/earth pin is larger in its diameter because: it needs to be able to withstand a...
10000 = 415 * i i = 10000/415 = 24 a <<>> The formula you are looking for when KVA is known is I = KVA x 1000/1.73 x E = 10000/1.73 x 415 = 10000/240 = 41.6 amps.
First let's get the units of measurement correct. Power and energy are two different things. kVA (or more commonly kW) is a measure of power. Use per annum would be a measure of energy, kilowatt-hours (kWh). Energy is calculated multiplying power (kW) times the number of hours (h) to get kWh.It...

Transformers can be reversed but their ratio remains the same. In  this case a 240 to 120 volt step down transformer has a ratio of  2:1. By reversing the transformer and using 180 volts on the  secondary side, there would be a potential of 360 volts on the  primary side of the transformer. Also...
No, the 12VDC adapter is specifically designed to charge a DC device. By applying 12VAC to the device could destroy it.
If you are reading a voltage it is the drop across the resistance to ground. To get rid of the voltage get the resistance lower. This can be accomplished by installing more ground rods to the grounding system. Utility companies usually like 3 ohms to ground or less.
Double pole wiring is checked the same way as single pole wiring. When you turn the switch on and the device works, in effect the switch is checked.
Electricity takes the path of least resistance - That is to say most of the electricity takes the path of least resistance.In this case the short circuit will have an incredibly low resistance, and the vast majority of the electricity will bypass your appliance, causing no damage (to the appliance)...
You pay for what you use. If the light is left on then it is costing you.
The advantages of safety are continued health, well-being and longer life. There are no disadvantages of safety, unless you think the being safe means not taking unnecessary risks, and you like putting yourself at risk unnecessarily.
VA or, more correctly, V.A, is the symbol for volt amperes, which is the unit of measurement for the apparent power of an alternating-current load. In A.C. circuits, true power (measured in watts) is a measure of the rate at which energy is supplied to the load, and reactive power (measured in...
50 mA is another way of saying 50 milliamps or 50 thousandths of an amp.
This maximum insulation resistance is in the order of Mega-ohms there's a good chance the insulation resistance tester (Megger) will max out it's display to look similar to this: >99MΩor whatever your display can show. The one we used frequently in work did. It was calibrated regularly to Irish...
To answer this question a voltage value must be added. Once this is done the wattage can be found by the following equation, W = A x V, Watts = Amps x Volts.
Generally speaking the longest part of replacing a fuse is going to the store to buy a new one.In household appliances the only fuse a user should be replacing is the one in the plug top, and this should take at most 5 minutes.Remove the plug from the wall, unscrew the center screw from the plug top...
Throughout the USA the normal supply voltage is 120/240 v in a  split-phase 3-wire system using a neutral and two lives with 240  across the live wires and 120 v from either live to neutral.  Appliances up to 1500 watts operate on 120 v and, above that, 240  v.   208 v three-phase is also...
In the grand scheme of things it could be called an output device. Also in the same train of thought it could also be called an input device depending on how you look at the overall picture of how it is going to be used.
In English sockets the brown wire is not considered to be neutral. It is considered the hot/live cable.The blue cable is the neutral.The relative voltages areBrown = 230voltsBlue = 0voltsGreen/Yellow = 0 voltsThe effects of crossing the blue and green/yellow cables is called neutralising and is...
This is a bad sign. Turn off power to the outlet at the breaker and call an electrician. Googling will provide more info.
All electrical conductors are surrounded by a magnetic field. By detecting this magnenetic field you can trace hidden electrical cables buried in walls using a cable tracer. More advanced versions of this type of tool are used to detect power cables buried underground.
The electrical connections for a fluorescent tube are quite small and also inside the lamp holder at either end of the bulb (2 on each end).Since you won't be able to put your finger into these connections regardless of whether the lamp is in or not, there is no real electrical hazard when removing...
The normal calculations for watts are as follows. amps x volts = watts volts2 / ohms = watts amps2 x ohms = watts <><><> Scroll down to the Related links and look at "Watts, Volts, Amperes, and Ohms".
A step-down transformer would be the best option. Use a 24 V transformer with a center tap, that would give you both 24 Volts and two 12 volt lines. Make sure the transformer can handle the amperage that you're trying to use. It's best to try to not drive the transformer over 75% of its rated...
Answer for USA, Canada and countries running a 60 Hz supply service.The NEC has more than one table that can be used for this determination. The necessary parameters include the intended purpose of the motor, the name-plate current rating (that's not the locked rotor rating) and the duty rating of...
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
When deciding the wire gauge for a residential application, there are only two things that matter, one being the amperage and the other is the distance. Assuming a normal residential application we can probably ignore the distance, but you MUST know the amperage that the AC will be using. If the...
There's a few small parts inside a GFCI and also a small coil of cable. Electricity in an AC circuit can be considered to vibrate in the cables, this produces unnoticeable harmonics (vibrations/noise). However when a coil (cable wrapped around and around) has AC Current flowing through it these...
  == Answer ==   Incandescent can be used with a dimer switch. Flourscent lamps, unless designed to be dimmable, cannot due to the ballast needed.
Loose wires. Corroded connectors.
The percentage of copper in a fuse wire is very small or non existent. Fuse wire is made from mixing different types of alloys together of aluminum, nickel, iron and chromium. The alloys result in compounds called cronifer and aluchrom. The composition of the different fuse wires results in how the...
There is zero amps in one kilo volt amp. The terminology of KVA is (K) kilo meaning one thousand, (V) for volt and (A) for amperage. What is missing from the equation is a given voltage. Formula for finding the answer is I = (VA or W)/V .
An ELR is terminology used in fire alarm systems. It stands for End of Line Resistor. It is used as a load on individual fire alarm circuits. This load draws a small current that is monitored by the alarm panel. What the panel is monitoring for is open circuits in break glass and bell circuits. If...
Power circuit carries high power and costly devices. If there is  some unwanted power signal(noise) in the wire it can damage the  device. To reduce this effect earth is necessary.   Lighting circuit carries low power(current).So, we ignore the earth  terminal.   Answer for UK   ...
The letters ACB stand for Air Circuit Breaker. These types of circuit breakers are used for high voltage switching. The breakers are usually enclosed in steel switch gear enclosures that are situated in electrical service vaults.
No it is not safe. Equipment labeled for a specific voltage must be operated on that voltage. The proper way to operate a 110 volt device is to use a transformer. You apply the 240 volts on the primary side of the transformer and use the 110 volts off of the secondary side of the transformer. To...

A breaker trips because the circuit load has tried to draw more current that the circuit is designed to operate at. You have to establish what the total current draw of the device is. This can be found on the manufactures label. There it will state what the normal amperage draw is for the specific...
There is zero watts in 10.5 amps. Watts is the product of amps times volts. Without the voltage value given, this question can not be answered.
This is a voltage drop question. To answer this question a voltage must be given.
In general yes. Now if you have access to a stream that can be dammed off at an elevation of 300 feet above your house, you will be able to generate your own power. The water pressure at your house from that elevation will be about 135 pounds. Pipe that pressure into a Pelton wheel that is connected...
Look at the current rating on the AC unit. If under 16 Amps use a 20 A breaker and 12 AWG wire.
As air conditioners come in many different sizes so will the cost to operate them. If you supply some values, a calculation can be made for that specific unit. The voltage and amperage and whether the unit is single phase or three phase are some of the values needed. Also needed is the time...
To answer this question a current value needs to be given. 125000 is the product of amps times volts. I = W/E = 521 amps. So to bring 240 volts up to 125 KVA you need the circuit load to draw 521 amps.
  == Answer ==   Air "fresheners" typically just mask odors by putting out a stronger odor. However, electronic air cleaners are also able to destroy some odors. High voltage (DC) is applied across two plates as air passes between them. Three things occur that result in destroying odors when...
It is metric that is used in the European standard of wire measurement.
Yes, that is exactly right for Australia.
