How much copper by weight is in one 50ft 20 amp extension cord?

depends on the wire gauge and strand type
sold strand 12 AWG wire is 50.57 feet per pound.
most extension cords however are not solid strand, they are multistrand line which allows for flexibility and breakage.
standard size is 28 AWG, 2067 feet per pound.
7 strand 12-3 line gives you 1050 feet of 28 AWG
or ~$2 worth of copper if its clean and bare, less if it still in its insulator or if the insulator is burned off.

Who invented the first electrical extension cord?
The extension cord was invented in 1904 by S. W. Atherton, an American inventor and electrical engineer.
How do you re-wire an extension cord green white black?
You can rewire your extension cord by replacing the existing wire with green, black and white wires. In most situations it is safer and cheaper to buy a new extention cord.
When should you use a 10 gauge Extension Cord or a 12 gauge Extension Cord in construction?
When the outlet is more than 40 feet away, or when you are operating 2 or more tools from it.
How do ibidentify the wire of an extension cord two wires?
It depends on the extension cord but I will give you 2 ways and they are each very simple. On a residential type (what I call a house burner) extension cord with just 2 conductors, you will find that the jacket of one wire is smooth and the other one has ridges. The one with ridges is your neutral or white conductor. On a more commercial type extension cord with conductors covered by a protective jacket, your conductors in the cord will be color-coded, with black being hot, white being neutral and green or bare being ground.
A gauge 14 extension cord can safely carry 15 A What will happen if several appliances drawing a total current of 18 A will be connected to it?
A 14 gauge extension cord can safely carry 15 amps, but not very far. Number 14 gauge extension cords are only rated for about 13 amps according to the labels on the cord. This is because the insulation is not intended to withstand the heat of currents above this level. Running this cord over 50 feet or loading it to 18 amps would be unacceptable.The likelihood of the cord maintaining the 18 amps for any amount of time for the high current to do any damage to the insulation of the cord is not very great. Extension cords are only an extension of the 15 amp wall circuit that they are plugged into. On overloading the extension cord by that amount the overload will trip the 15 amp supply breaker. An example of this is jamming a circular handsaw when it is plugged into the end of a 50 foot extension cord. The next action that is taken is to reset the tripped breaker.
What qauge extension cord is needed for a block heater?
I would use a 12/3 cord especially if your going 50ft or more from the outlet.
Is it acceptable by OSHA to plug an extension cord into another extension cord-?
You can plug an extension cord into another extension cord. A extension cord is to help make doing something easier.

How many amps will a 12 3 extension cord handle?
A #12 copper wire is rated at 20 amps. On an extension cord, unless it has user installed ends, the rating of the three blade cap is only 15 amps. Either way the extension cord should only be loaded up to 80% of the wire rating. 20 x .8 = 16, 15 x .8 = 12.
Does a long extension cord draw more power than a short extension cord?
No. However, a longer extension cord has higher resistance for a given wire gauge or size compared to a short extension cord and the voltage at the load device may drop so low that it doesn't work properly. This may also be accompanied by a noticeable rise in the temperature of the extension cord. As a rule, use the shortest extension cord that will get the job done. If the extension cord must be long, use one that has heavy gauge wire to minimize voltage drop at the load.
What is the use of extension c holder?
An extension cord holder is used to hold an extension cord. It wraps around the holder, for easy release and withdrawal.
What is the amp rating of 14-3 extension cord?
A #12 copper wire is rated at 20 amps. On an extension cord, unless it has user installed ends, the rating of the three blade cap is only 15 amps. Either way the extension cord should only be loaded up to 80% of the wire rating. 20 x .8 = 16, 15 x .8 = 12.
Is it safe to touch a extension cord while its plugged in?
Yes, it safe to touch a extension cord while its plugged in.
Can you plug in an iPod touch wall charger to an extension cord?

What size extension cord should you use for your 120 volt 1725 watt iron?
#16 <<>> To load an extension cord to 1725 watts depending on the length of the cord, the bare minimum should be #14. A better size cord and my recommendation would be a #12 wire size extension cord.
