What is the insulation factor for a number 6 wire?

The main insulation factors of the wiring used in every day use are 60, 75 and 90 degrees C. A #6 wire can be any of the above. The higher the insulation factor, the higher the ampacity of the wire becomes.

For a #6 wire the amperage is 60 C - 55 amps, 75 C - 65 amps and 90 degrees C - 65 amps.

Is 0.83A the same as 500mA?

No. 0.83 Amperes = 830 milliamperes. 1A = 1000mA, it's a base-ten system, just like meters or liters.

What is an MA fuse?

It is a fuse that is rated in one thousandths of an amp. An example, a 500 mA fuse can also be called a 1/2 amp fuse.

Can you change the direction of a 110v electric motor?

The answer to that question is entirely dependent on the motor. Many motors have an access plate where the power feeds into the motor. Removing that plate often reveals a wiring diagram that shows how to change the wiring to reverse the motor direction.

But most AC electric motors do not provide the option of reversing direction.

What is series in electricity?

Watch Episode 12 Season 4 of how i met your mother it answers it.

Will a switching power supply work on 277 volts?

Not unless it is rated for that voltage. You can likely find a step down transformer from 277 volt sto 120 volts.

What happpens when the anode and cathode touch?

A short circuit occurs. Depending on the potential sparks, fire and other bad things may happen.

What did the people in the old days use when electricity never evzizted?

People used candles , coal oil lamps and wood stoves, then later on they used gas until electricity was invented.

What is the basic working principle of Refrigerator?

A refrigerator works by compressing and expanding a fluid in order to effect a heat transfer from the medium being cooled to the atmosphere where it is allowed to dissipate. The basic system works as follows:

A fluid is compressed which causes it to heat up, this is pumped through a coil which transfers the heat of compression to the atmosphere or other fluid this cools the fluid in the system, the fluid is then expanded through an orifice where it cools even further as a result of the expansion (no heat transfer actually occurs, it's what "causes" the expansion), this then passes through another coil inside the refrigerator where it absorbs heat from the air inside the refrigerator, this heated fluid then passes back to the compressor where it is compressed again causing it to heat up again and the cycle repeats.

What type of light is hazardous and intense in welding?

Electric arc welding produces intense ultraviolet light, which is very hazardous to eyes and skin.

What does the B in 14NM-B stand for?

The B indicates that the conductor insulation is rated at 90 degrees C.

Why would you use iron to replace power lines?

If Iron conducts eleticity long distances better than any other metal then that would be one reason.

Why do my earphones keep breaking and how can I try to keep them safe so they do not break about every 3-4 weeks?

don't bite them that's what i do it wrecks them. um thts all i don't know if theres another way you can break your earphones

How many pages are in the 2005 NEC Code Book?

The paperback version of the 2005 NEC code book has 792 pages. It is written by the National Fire Protection Agency. It is the standart for electrical and wiring regulations.

How do you find power in a series circuit?

Power dissipated by the entire series circuit =

(voltage between its ends)2 / (sum of resistances of each component in the circuit).

Power dissipated by one individual component in the series circuit =

(current through the series circuit)2 x (resistance of the individual component).

What gauge of wire is each strand of cat 5?

Cat5 cabling normally uses 24AWG solid conductors.

An electrical shock is a body reaction to what?

An electrical shock is an electrical current that flows through the body.

The following list is the tolerances that the body can stand.

Less than 1/2 milliamp no sensation

1/2 to 2 milliamps Threshold of perception

2 to 10 milliamps muscular contraction

5 to 25 milliamps painful shock (may not be able to let go)

Over 25 milliamps Could be violent muscular contraction

50 to 100 milliamps Ventricular fibrillation

over 100 paralysis of breathing.

What is 1000 ohms?

"1,000 ohms" is the resistance of anything through which the current, expressed

in amperes, is numerically equal to 0.001 times the potential difference between

its terminals, expressed in volts.
