Do you need a starter for a 3 phase 5 horse motor?
YES. USE THE NORMAL DIRECT-ON-LINE OR ACROSS-THE-LINE STARTER.
Should you read everything at the same speed?
Personally I do not think so. Especially if you are reading to someone or for enjoyment. The inflection, tone, and speed, need to vary according to the mood. However, if it is research, then do whatever helps you to assimilate the information better.
Don't do this! The fuses and breakers on a 240 Volt circuit should be left as they are, to supply 240 Volt appliances and nothing else. It is only safe to install a new 120 volt circuit by fitting a new 15 Amp breaker and run new wiring of the correct size for the length of run, all the way from the breaker panel to the new 120 Volt socket outlet.
Before you do this you must check the wiring code for your locality (town/state) to be sure you know if the new circuit needs a protective device such as a GFCI or RCD.
In most places a GFCI or RCD will be mandatory if the new socket outlet is to be installed in a place that is likely to be subject to water spray, wet or damp floors, walls or ceilings. This includes kitchens, bathrooms or shower rooms, or anywhere outside the building such as pool areas. <><><>
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 happens during a lightning storm?
suddenly induces high voltage in the transmission line because the charge carrier in the transmission is positive and the charge present in the lightning storm is negative so if colloid both increases its field and voltage
when two or more clouds rub they produce friction this leads to lightning which produce light , sound and heat .
How many watts per hour will a unit that is rated at DC 12V 500mA consume?
Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp)
Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second
Out of 8 cables in a wire which is esssentially need to be correctly crimped?
FOR CAT 5 OR CAT 6 LAN CABLES -- ALL SHOULD BE CORRECTLY CRIMPED AND ITS COLOR CODING ARRANGEMENT TO SERVE ITS PURPOSE.
Will a hps luminaire run a metal halide lamp?
Yes the ballast and starter are the same
you can run halide in hps, but not hps in halide.
TACHOGENERATOR IS USED TO CONVERT MECHANICAL ENERGY INTO ELECTRICAL ENERGY OR MORE SIMPLY CONVERT REVOLUTION OF THE SHAFT OF A GENERATOR TO A ANALOG VOLTAGE
How do I build a 30 second timer that resets?
Do a google search for: 555 timer circuit You will find hundreds of circuits you can use.
How does parallel circuits work?
A parallel circuit has more than one resistor (anything that uses electricity to do work) and gets its name from having multiple (parallel) paths to move along . Charges can move through any of several paths. If one of the items in the circuit is broken then no charge will move through that path, but other paths will continue to have charges flow through them. Parallel circuits are found in most household electrical wiring. This is done so that lights don't stop working just because you turned your TV off.
Why should a transformer not be used on direct current?
Think of a transformer as a foot pump. Putting pressure on it will cause it to pump air but you need to release the pressure to do it again.
The transformer does the same for electricity, if DC is applied to it it will create one pulse of current from the output but that is all. You need the continues rise and fall of AC to work the pump.
Fuse maps are found inside programmable logic devices. The fuses are selectively blown during programming of the device to cause it to have the desired operation.
How effective is a geothermal heat pump?
It's very effective and efficient. It of course uses the earth's heat for heating a building. Only a small amount of electricity is needed for this, compared to the large amount needed for an electric furnace or baseboard heater. Geothermal is very expensive to install, but will make up for the cost in the savings you will have over a period of several years.
Who is the creator of Spider-Man 3?
The creator of spiderman is roshane riyon The creator of spiderman is roshane riyon The creator of spiderman is roshane riyon
A charged body is an object that has an imbalance of positive or negative electric charges. This can occur through the gain or loss of electrons, resulting in the body having a net electric charge. Charged bodies can interact with each other through electrical forces.
What are Resistors wired in series?
Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.
What kind of electricity do dams create?
hydroelectric power They produce what is called 3-phase AC power.
When were wind turbines invented?
The first wind turbine was invented in 1888. The fellow who invented it was Charles F. Brush.
A jdr is a type of halogen light bulb. These bulbs have a screw in base, that is one size smaller than a standard household base.Ê
What does the voltage regulator do on a generator?
A voltage regulator controls the output voltage of a generator. This ensures only the specified ÊvoltageÊis supplied thus preventing damage to the circuit and other electrical appliances.Ê
Why is a cracked plug socket can cause a potential fire hazard?
The cracked plug can cause the wires to spark and cause a fire. When the wires are plugged into it where the crack is the wires can touch the socket and cause the fire.
Why can't glass conduct electricity?
Glass is an insulator because its structure does not contain free electrons that can move freely to conduct electricity. The tightly packed atoms in glass create a strong ionic bond that does not allow for the flow of electric current.
What makes an electric pencil sharpener work?
An electric pencil sharpener works by means of a small electric motor. The motor rotates the blades, sharpening the pencil.?æ
What kind of battery can power a 40 watt light bulb?
If the bulb is a 40 watt, 120v bulb, you would need 20 6 volt batteries wired in series, or 80 (!) 1.5 volt batteries. 1.5 volt batteries are AAA, AA, C, D, etc. Since this solution is rather extravagant, try finding a light bulb made for an RV. These typically run off of 12 volts, and you can get a single 12 volt battery, or 2 6 volt batteries, to run this bulb.
