Not in general. You can buy extension cords in a variety of lengths. However, the longer the cord the more the resistance and the bigger the voltage drop across the length of the cord. If you were using the cord outdoors and the junction was on the ground it is possible for moisture to cause a short at the junction.

Is it acceptable by OSHA to plug an extension cord into another extension cord?

In Canada this is quite acceptable. One extension cord can be plugged into another extension cord. What has to be kept in mind though, is the load amperage at the end of the cords. Additionally plugging one cord into another increases the wire's total resistance. This effects the over all voltage drop of the cord, by lowering the voltage at the load. If the cord's wire size is increase in each additional cord added to the length, this would be one way to combat against the voltage drop. An example, if the first cord has a #14 size conductor the next size cord to plug into it should be a #12. If additional length is needed then the next size cord to extend the length should be a #10.This type of cord use is used on construction sites all the time. Keep in mind that extension cords are only to be used as a temporary source of power in temporary locations and they not to be used as a permanent installation power source.


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 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.


What is the most number of outlets on a multi outlet extension cord?

The most number of outlets on a multi outlet extension cord are six. Any more then six outlets on an outlet extension cord and it would become dangerous.

Why does the current change at an extension plug when connected to a lamp?

Are you saying that you plug in a lamp and another lamp on that extension cord goes dimmer? If so then the extension cord wire is of a smll guage size and causing a voltage drop from the outlet to the cord output.
