How do you install electrical wiring for room aircon?
More information is needed, maybe a lot more. Depending on its size you may need a new circuit for it. If you trip the breaker then don't use it and get a new circuit installed for it on its own breaker.
You are probably talking about a window unit. If it is a simple 5000 BTU unit you can probably plug it into the nearest receptacle. If you trip the breaker then you need to run a new circuit for it.
If it is much larger you may need to run a new circuit.
If it is a 240 volt unit then you need a new circuit.
Can you use dry location electrical boxes under covered patio?
As long as there is no possible way that the boxes can get wet, a box for a dry location can be used. This includes rain or a possible soaking from a garden hose or sprinkler system. If there is a possibility then an FS series box will fill the bill for a waterproof box.
A natural gas generator connected to the grid has its voltage and speed (frequency) stabilised by being connected to the grid.
All generators on a grid run synchronously, and it happens because if one generator has a tendency to lag behind it will produce less power and thereby maintain its speed.
What is frictional kw ac motor?
Tesla is a pretty large unit; a 1 T coil is an extraordinarily powerful device. No, you cannot build this from parts worth $60 at the local hardware store.
How can you hook a 230v 3 phase lathe to 480v 3 phase incoming power?
Inspect all motor labels and see if they are dual voltage motors. If they are, they should have a label on them telling you how to convert the motors for 480 volt. This is a relative simple task. Converting to 480 volts will lower the motor current to half of the 230 volt rating, so you will have to change the overload heaters in the individual motor starters. You need to do this to protect the motors in case of overloading. Last the control transformer will need to be reconnected for 480 volt.
How do you wire a hobart p660 3 phase mixer?
The information from the equipments nameplate is needed to answer this question in a complete way.
How much will it Cost to upgrade an electricity supply from phase 1 to phase 2 for a Melbourne home?
If you are asking whether it is possible to upgrade from single phase to two phase, then you should understand that a two phase system is archaic and will not be available from your electricity supply company. If you are asking whether your company can supply two lines (out of three) it's quite unlikely -they will normally supply single phase or three phase! You can likely upgrade to three-phase if you have a reason to do so -e.g. to operate three-phase motors. As for the cost -you'll have to check that our yourself!
The information of, if the fuse is a slow blow or not, is printed on the fuse. In electrical terminology it is known as a time delay fuse. Smaller glass envelope time delay fuses will have a spring mechanism that can be seen through the glass envelope. Time delay fuses are used in circuit that have a high inrush current when the device is first switched on. A good example of this would be an electric motor. The bead of solder on the end of glass fuses is how the spring is supported to the end cap of the fuse.
How can you connect current transformer to ammeter in three phase?
You use three CTs, one per line conductor, each feeding a separate ammeter,
Can a 3 phase motor be converted into a single phase motor?
A three-phase motor will not start if one or two phases aren't connected. If while running one or two phases "drop out", it will continue to run for awhile, but will eventually burn out, unless connected to a motor saver.
Can the neutral conductor be downsized in a 3 phase electrical system?
Yes, you can reduce the neutral in a three phase system. you must figure the unbalanced current the neutral will carry and also make allowances for any harmonics that may be present.
What is common example of an insolator?
Rubber is probably the most common you'll see for protective gear. Certain polymers are used for wiring insulation, but really most things that are derived mostly from nonmetal elements are excellent insulators.
List 5 materials that electricity does not flow through well?
1.rubber
2.glass
3.plastic
4.wood
5.cloths
This are some materials that electricity not flow through (I think)
What plug and and socket outlet type and size is used for 40 amps?
Answer for USA, Canada and countries running a 60 Hz supply service.
50 amp.

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 line side of the 3 phase transformer?
The primary line side of a 3 phase transformer should be marked H1, H2, H3. The line side is the incoming voltage that you want to step up or step down or isolate.
What electronic has the most gold?
Depends, if you have access to acids then computer boards and CPUs have the largest supply of gold but there are small amounts of plating on phones, computers, etc that can just as easily be removed with pliers.
It's Basic Project Of Transmitter & Receiver circuit
<<>>
Poly-chlorinated-biphenyls, it is a oil used in transformers to dissipate the heat from the coils of the transformer to the transformer's case. This helps in the transformers cooling. The only problem, it was found out after many years of use that it is toxic to the environment. Zero PCB's is the terminology used for the new transformer oils that are not PCB based.
What does L1L2L3 on a three phase motor mean?
Three phase alternating current systems are either 3-wire systems or 4-wire systems. In the case of a three-wire system, each 'wire' is properly called a line conductor. A four-wire system comprises three line conductors and a neutral conductor.
Line conductors can be identified by letters, or by colours. If they are identified by letters, they can be L1, L2, and L3, or A, B, and C, or R, S, and T -depending on the national/international standard adopted. If they are identified by colours, then these may be red, yellow, and blue, or brown, black, and grey -again, according the the national/international standard adopted.
If you make the connection, the breaker on the generator will trip. The motor will not get up to running RPM. Check and see if the motor is dual voltage. If it is, run it on the higher voltage. This will reduce your run current to about half of what it is on the lower voltage.
What is the starting current of 10 hp motor?
p= V*I*COS FIEE SAY COS PYE IS UNITY
10*1000=230*I*1
I= 10000/230
I=43.4 A
Comment10 kW is the output power of the machine. You will need to know the machine's efficiency in order to determine its input power before applying the above equation.
What does the phases on a nameplate of a motor mean?
On a three phase motor, the phases give you direction for how to hook the motor up to make it spin one direction vs. the other. If you hook up such a motor blindly with all three phases, it may spin in the opposite direction you want; to fix, you swap any two of the three phase connections.
What is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
