Dryers usually contain a front loading tub with holes for ventilation. This tub rotates and is powered by a belt at the back from an electric motor in the back corner. Some have a heater tunnel with an electric heater and a fan forcing hot air into the tub. Others may have a gas heater, similarly forcing hot air into the tub. There are many heat sensors and auto shut off switches in case they get too hot. Most dryer problems are caused by these switches or broken belts.
How do I fix a flickering kitchen light?
You didn't say what kind of light which would have been a good clue. If a fluorescent it could be a bad tube or bulb, a bad starter or a bad ballast. If an incandescent light could be a loose connection or a disconnected filament that is making intermittent contact due to vibrations.
How do you calculate the fuse rating level if the full load is 4 amp?
To calculate the fuse rating level, you typically want to choose a fuse that is slightly higher than the full-load current to avoid nuisance tripping. For a full load of 4 amps, you could choose a fuse rating of 5 or 6 amps.
One kilo volt amps is equal to how many horse power?
One horsepower (hp) equals 746 Watts (W), regardless of voltage (V). Kilo-Volt-Amps, often expressed as "KVA" is a commonly used unit of power. 1 Watt is defined as 1VA. 1 KVA equals 1000 Watts. 1 HP = 746 Watts = 0.746KVA and therefore 1KVA = 1000W = 1.34hp
What are good electricity answers websites?
Some good electricity answers websites include Energy.gov, EnergySage, and The Electric Power Research Institute (EPRI). These websites offer reliable information on various electricity-related topics such as renewable energy, energy efficiency, and the electric grid.
winging is always constructed in 360 degrees angle. 3 phase winding is built after 120 degree angle. If a 2 phase phase wingind is designed, it is 2 , 180 degree angles winding, which is exectly same as 2 coils in series. Similarly, 4 phase has same effects, a pair of 2phase winding.
In 480 volt three phase what is the tolerance of the voltage?
It is typically accepted to be 440 to 500, based on 110 to 125V for common power outlets.
This is based on experience in the USA with 60Hz power supplied by utility companies.
Since 3-phase is mentioned, you should also state if this is delta or wye configuration, and whether you are measuring from phase to phas or phase to neutral.
For a more competent answer, an electrician should refine this answer, or you could look up the relevant standard, probably an ANSI standard.
What color is the positive in a 240v ac power cord?
There is no "positive" wire in an Alternating Current (AC) system, which is what a standard AC power cord or flex is used on. In a cord or flex for a small electrical appliance there is a always a "Hot" or "Live wire, a "Neutral" wire and maybe also a "Ground" or "Earth" wire. The "Hot" or "Live" wire is colored * Black in the US, Canada and other countries using a similar 60 Hz household AC power system.
* Brown in Europe and other countries using a similar 50 Hz household AC power system. The "Neutral" wire is colored * White in the US, Canada and other countries using a similar 60 Hz household AC power system.
* Blue in Europe and other countries using a similar 50 Hz household AC power system. The "Ground" or "Earth" wire is colored * Green in a cord or flex in the US, Canada and other countries using a similar 60 Hz household AC power system.
* Green and Yellow in Europe and other countries using a similar 50 Hz household AC power system. For more information please click on the Related Questions shown below.
Why does liquid pentane not conduct electricity?
Liquid pentane does not conduct electricity because it is a nonpolar molecule with no charged particles or ions that can carry an electric current. In order for a substance to conduct electricity, it needs to have free-moving charged particles, such as ions or electrons, which are absent in liquid pentane.
What is no volt protection in motor circuits?
No Volt protection is a method of motor starting that ensures personal and equipment safety by disconnecting the power from the motor in the event of a power fail.
If an isolating switch only was used, following a power cut the device could start without warning, and injury or damage could occur. No Volt protection uses push button switches and contactors wired in such a way that when the power fails, the hold on relay releases and the motor will not start until the operator presses the start button.
In most countries this is mandatory, In New Zealand or Austrailia, this is mandated by AS/NZS 3000
What gauge wire is used to carry 120 volts?
You need 14-gauge wire for 15-amp circuits, and 12-gauge wire for 20-amp circuits.
<<>>
The question is confusing the ability of a wire to carry current, with the insulation factor of the wire. Any size wire can carry 120 volts. The insulation factor determines how much voltage can be applied to a wire. Standard wire voltages come in three voltages, 300, 600 and 1000 volt ratings. These ratings are up to and including, so 300 volt insulation wire will handle 120, 208, 240, and 277 volts. 600 volt insulation will handle all of the 300 volt range plus 347,415, 480 and 575 volts. 1000 volt insulation will handle all of the 300 and 600 volt ranges plus different voltages up to 1000 volts.
Can I run a 230 volt 20 amp table saw on 10 3 with a 250 foot run?
Yes you can. If you don't need 120 volts at the saw then you can use 2Conductor # 10 copper wire. FYI, don't know if you know it, but you don't count the bare ground wire in the conductor count. Anyways With # 10 wire you will get a 6 volt drop at the end of 250 feet which is 2.5% leaving you a working voltage of 234 volts.
How many volts come out of an Australian power point?
As of 2000, Australian power points supply AC 230v at 50hz. Pre-2000, it was 240v at 50hz.
Yes, 220v is the "standard" wall-voltage in Europe.
Your stuff should work in the UK, If:
(1) Your appliance is rated for 220 volts.
(2) You have the correct plug adapter, since British plugs are not even remotely similar to US plugs.
No, a single-phase oven cannot be wired to a three-phase circuit without a transformer. The electrical systems are incompatible and may result in damage to the oven or the circuit. It is recommended to use the appropriate circuit or consult with a licensed electrician for proper installation.
It is not recommended to supply a 240 volt single phase motor with only one phase until the other phase is closed. This can cause imbalanced current flow, leading to motor overheating and potential damage. It is best to provide both phases simultaneously to ensure proper operation of the motor.
What gauge wire is required for electric dryer?
Most North American homes use a 40 amp breaker for the range fed with a #8 copper wire.

If you had to ask this question here you need to learn more about your local wiring code re all the items you must use for a new household AC power range circuit.
Serious home fires can result from incorrectly installed new circuits.
So that the new installation is safe and legal - and complies with the terms of your home insurance policy - you must use the correct type and size of cable, the correct type of circuit breaker and the correct type of wall outlet.
From the local wiring code, a licensed electrician will know which size of wire to use because the answer depends both on the current to be carried (amps) and on the length of the run from the breakers on the main supply panel to the place where the outlet for the kitchen range is to be fixed.
Another answer
You probably shouldn't be installing a range cable if you can't calculate the load and cable size.
Wire size needed depends on the distance from the breaker panel to the outlet for the the range and the power of the range: 5 kW, 8 kW, 12 kW? Each require a different wire size.

What is meant by Phase Shifting?
Phase shifting basically means moving the reference from where the wave starts along x axis. For example, sine wave and cosine wave are basically similar, but have different starting points along x axis. Therefore, it's clear that shifting a sine wave by 90 degree towards negative infinity will give cosine wave.
