What is protected creepage distance of insulators?
dry arching distace of insulator is called protected creepage.
Can a 240 volt receptacle go on a 15 amp circut breaker?
In North America you would need two 15 amp breakers to obtain 240 volts. The wire for a 15 amp circuit would be #14 AWG. So to answer the question, yes a 240 volt receptacle can go on a 15 amp circuit.
What will happen with no electricity?
At some point in your life you must have lived through a power failure. Without electricity this is what your life would be like year after year. Very inconvenient.
What are the reasons for fire in a control panel?
To control and power are fire alarm system. You can manually sound, silence, disable alarms. You can dis-connect circuits when doing work. They usually have battery back up so that the system remains powered up when there is a power failure. (They are mains powered).
They can also be connected to the local fire service, so when there is an alarm condition, then it automaticaly calls the fire service to quickly arrive in the case of a fire.
It may also be connected to realy devices to turn off big machinery. When there is a fire alarm, all dangerous machinery that could add to the cause of the fire will be switched off for safety reasons.

Most fires in a control panel are caused by a short circuit in the control wiring. This can be caused by improper fusing of control devices. Some control panels are installed in a dirty combustible environment which leads to a contamination build up due to the panel door not fitting tightly. I have found 6" of wood chips in the bottom of the panels due to poor maintenance practices. Control transformers are another location a fire can start in a control panel.
Some are, such as silicon and germanium. Others are non-conductors known as insulators, such as glass.
What is quad cable with CAT rating?
Dunno.
"Quad" usually refers to the shielding (such as TV antenna coaxial cable), "CAT" usually refers to four-pair twisted pair.
"CATn" (CAT3~CAT6) is four-pair, twisted-pair, unshielded cabling most commonly used in Ethernet computer network cabling.

Wiring diagram Murray riding lawn mower?
Murray 12hp/38624x12b has a unmarked 6pole ignition switch,i don,t have the orginal switch so i don,t know if this is the right one. 1993 has no info.
Which property makes it difficult for current to pass through?
Resistance in the circuit makes it difficult for current to pass through.
What could cause wires to burn out?
Too much current being applied or the wire not being a large enough (gauge), will cause wires to burn out.
The flow of electricity can be compared to the circulation of water in a?
A pipe. The volume of water available can be compared to voltage. The diameter of pipe could be compared to resistance with smaller diameter being larger resistance and the flow of water past a point in pipe is equivalent to current flow.
How does static electricity clean chimneys?
- Smoke particles pick up a negative charge.
- Smoke particles are attracted to the collecting plates.
- Collecting plates are knocked to remove the smoke particles.
In your home your stove and your electric clotes dryer usually run on how many volts?
Usually 220 to 240 VAC.
Becuase it is a natural resource and if we run out then we will never have any ever again
Is the white wire safe to touch?
Never assume that any electric wire, no matter what color it has, is safe to touch.
What does two fuses in series do?
Two fuses in series could be used as a tap point to pull current to another circuit between the fuses, some times there is a surge fuse designed to blow in the event of an outside voltage surge or a sudden appliance surge due to internal failure.
Obviously you can attempt to use it for something else, such as an air compressor, but it is NOT SAFE to do it!
You could drive around on the wrong side of the road but it is NOT SAFE to do it!
You could put your hand into a fire and hold it there but it is NOT SAFE to do it!
In general the reasons for saying it is not safe to use something other than a dryer on a dryer outlet are all about being sure that the circuit you will use for the air compressor has:
- the right size of wires to carry the current and
- the right size of breakers on the main supply panel to protect the air compressor - and the wiring to it - from catching fire if there is ever a malfunction.
Air compressors are quite different to dryers and you have to be sure you wire them up correctly and safely to avoid there being any kind of risk of anyone getting electrocuted.
As you asked this question here, the best advice anyone should give you so you can use your air compressor with no worries is to ask a licensed electrician for his advice. He can also quote you for installation of the correct type of outlet, wiring and breakers on the main supply panel to power your air compressor safely.

Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you put just one wire in the wrong place you risk being killed by electrocution or you could even start a house fire.
How to do this http://jobs.answers.com depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact location of the appliance you wish to install. If it is anywhere that is subject to water splashes or spray - such as in any room supplied with running water pipes, like a kitchen, bathroom, shower room, etc., or outside in the yard or by a pool-side area - in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician.

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.
