Why 24 volts light to be used in confined space?
It is to reduce the impact of electrical shock to the workers (in case any). By having less voltage the consequence would also be diminished. Installation with higher voltage (110 V, 220 V, or 380 V) is possible to create a fatal incident depending upon the environment (wet, metal surface, etc.)
Where can you find the power rating of an electrical appliance?
Normally the power rating of an electrical appliance can be found on its 'Rating Plate' or, if there isn't one, use the following formula W = A x V, where W = watts, A = current and V = voltage.
How do you rewire a 110 volt HID Magnetic coil ballast to use 220 volt?
Rewiring a 110 volt HID magnetic coil ballast to operate on 220 volts would require replacing the existing ballast with one designed for 220 volts. Attempting to rewire the ballast could lead to overheating, electrical failures, or even safety hazards. It is recommended to consult a professional electrician or purchase a new ballast suitable for 220 volts.
On the 20 volt range meter show 0.96 does this mean ninety six hunderdth's of a volt?
Yes. On the Scale, 20.00 would be 20 Volts and 01.28 would be 1.28 Volts.
Therefore, 0.96 would equal 0.96 V or 960 mV
It is generally safe to use a 230V 50Hz appliance in a 220V 60Hz outlet, as the difference in frequency should not significantly affect the operation. Make sure to check if the appliance is dual voltage compatible and be cautious of potential power surges or overheating. However, it is always recommended to use a voltage converter or transformer for long-term use to prevent any damage to the appliance.
Can a 277 unit heater be supplied with 240 volts?
No, a 277-volt heater cannot be safely operated with a 240-volt power supply. Matching the correct voltage is essential for the safe operation of electrical devices. Using a lower voltage than the device is rated for can lead to insufficient performance and potential damage.
Can a 135 volt bulb replace a 120 volt bulb?
Yes, and the 135V bulb will last longer than the 120V bulb because the filament is thicker.
The downside is that the higher voltage bulb will not be quite as bright, and its light may be slightly more yellow in color (the color temperature will be less when run on a lower than design voltage).
What does 400mA mean on a light?
400mA refers to the amount of current the light consumes when it is operating. It stands for 400 milliamperes, which is a unit of electrical current. Knowing the current consumption can help you select the appropriate power supply for the light.
Is 1.5 volts of electricity dangerous to people?
1.5 volts is not nearly enough voltage to harm anyone or any animal. You body has about 500 ohms of resistance which is entirely too much for 1.5 volts to push current through your body at a detectable level.
Will a light bulb light if its metal tip rests on metal casing?
No, a light bulb will not light if its metal tip rests on a metal casing. The metal tip of the light bulb needs to be connected to the electrical circuit in order for it to light up. Resting on metal casing would not provide this connection.
Will 120 - 277 volt electronic fluorescent ballasts work on 208 volts?
NO! a 120-277 electronic ballast requires one "hot" wire and a neutral from either a 110V or 277V supply. If you supply it with two "hot" wires from a 208 V supply, it will instantly burn up.
Yes. A ballast with a specification range of 120 volt to 277 volt will work on 208 volt. These ballast use intelligent voltage sensing technology and it does not matter if the source is a hot and neutral or two (2) hots. Don't believe it? Call a ballast manufacturer instead of giving incorrect answers.
Can you run a 115 volt 15 amp air conditioning unit on a 110 outlet?
Residential power is usually 115 volts to 120 volts and will power a 15 amp air conditioner. If it is on a 15 amp breaker it may heat up the breaker and cause it to trip if it runs continuously in which case you would need to move it to a 20 amp circuit.
A 20 amp circuit will handle 18 amps continuously without overheating the breaker and making it trip. A 15 amp circuit can handle 12 amps continuously without over heating the breaker.
You cannot simply replace the 15 amp breaker with a 20 amp breaker because the 15 amp circuit uses smaller wire which might overheat.
The term 110 is an old one. Most home power now is at least 115 volts.
Outlet that reads 120 volts but you plug anything into it it burns it up?
The outlet may have a wiring issue causing a short circuit or an overload of current flow. It's important to have the outlet inspected by a qualified electrician to identify and fix the problem to prevent further damage or fire hazards. Avoid using the outlet until it has been properly repaired.
Can a 120 volt appliance run on a 110 volt circuit?
Yes. Circuits in a home are 120 volts but people tend to call them 110 volt circuits. The 120 volts you read on the appliance is the maximum voltage the appliance can handle. The actual voltage you will read at any outlet will range from 110 to 120 volts.
Can you use a 130 volt swimming pool light bulb in a 120 volt swimming pool socket?
No, it is not recommended to use a 130-volt bulb in a 120-volt socket as it can lead to potential safety hazards. The bulb may burn out prematurely, overheat, or cause damage to the socket and wiring. Always use the recommended voltage bulbs for your light fixtures.
How do you calculate kilowatts per hour?
A kilowatt hour is calculated by adding the watts together and deviding by 1000, this will give you kilowatts (kW). Then work out how many hours you are using this load for. multiply the kW by the hours and you get kWh. eg 15 lamps at 100w = 1500w/1000 = 1.5 kW. If these were left on for 6 hours then 6 x 1.5 = 9 kWh.
Answer
There is no such thing as a 'kilowatt per hour'. It's rather like saying 'kilometres per hour per hour', because a kilowatt is a special name given to a joule per second -in other words, it measures a rate.
If more and more appliances will be connected in a parallel circuit what do you think will happen?
Appliances have to be connected in a parallel circuit to keep the voltages the same for each appliance (they were designed to work with one voltage) , this does not mean that the power output will be the same, the more appliances there are the more current (i.e. power) will be needed to for the appliances and this can go on until the grid cannot supply any more (and you blow a fuse)
Will an electric grill 220-240 voltage 50HZ output 1800 watts work in Los Angeles?
An electric grill presumably is just a heating element, and so shouldn't be bothered in particular by the 60Hz rather than 50. 220V is available, but primarily for large appliances and such in the US. You might have trouble finding an outlet you can actually plug into.
To create a 220 volt connection using two 110 volt lines, you need to connect them in series. Ensure the two 110 volt lines are out of phase (provide opposite polarity) and then connect them together. This will result in a 220 volt supply for your concessions stand. It's important to consult a professional electrician to ensure proper wiring and safety.
Can you rewire a 240v lamp light fitting or small appliance to 110v and if so how?
It is not recommended to rewire a 240v lamp light fitting or appliance to operate on 110v. This can be dangerous and may lead to overheating, electrical fires, or damage to the device. It is safer and more practical to use a voltage converter or purchase a new device designed to work with 110v.
A heater element draws 13A from 230V supply What is the power rating of this appliance?
The power rating of the appliance can be calculated using the formula P = V x I, where P is power in watts, V is voltage in volts, and I is current in amperes.
Therefore, the power rating of the appliance is 2990 watts (13A x 230V = 2990W).
Would 230 volt item applicance work on 220 volt in south Africa?
Yes, a 230-volt appliance should work fine on a 220-volt outlet in South Africa. The small difference in voltage is usually within the tolerance range of most appliances. However, it's always a good idea to check the appliance specifications to ensure compatibility and avoid any potential damage.
Will UK electrical appliances work in Ireland?
In general, no, European appliances will not work in the US. Small appliances will have a Eurocord plug, which expects 230 volts and 50 Hz. With a transformer, you can convert a US outlet to a Euro outlet, but for many appliances the difference between 50 Hz and 60 Hz will prevent them working in the US.
What voltage do appliances use in the UK?
You have to understand some basic electrical principles..voltage is best under stood as pressure{as in water pressure}but not water of cause.110volt has less pressure than 240volts.manufactures gauge their appliances to work with 240 volts. 110volts this conversly is less pressure so that items will not work as it should or not work at all..
If the suppliers of electricity allow more or less than 240volts into the local grid this again alters the way appliances react..an electrical shower for example will give a greater kw output..hotter shower, if the voltage is more that 240volts, the manufactures build in a tollerence and a cutout, so this doesnt harm your shower...using the formulae amps=watts/volts is useful to find out the difference how many amps you end up with regarding the voltage you use.
A 240 volts incandecent lamp{those with filaments}will work but will offer a dim light..electronic type lamps whose operating voltage is stated on the side of that item 240 will not work.. Clear as Mud.I hope not...
