The terminology in the electrical trade as to duty cycle refers to the amount of "on time" as to the "off time". When referring to equipment that have a high current on time, it is usually using components or wire that are sized smaller than what they should be and can not cool themselves.
These components can not dissipate the heat generated quick enough and can only be on for a certain amount of time. This type of equipment is given a duty cycle. The duty cycle has to have an equal or greater off time to let the equipment cool down. It is this ratio of "on time" to "off time" that is the equipment's duty cycle.
For example, motors due to their design usually have a 100% duty cycle, meaning that the motor can operate continuously without having to be shut down to allow it to cool off.

What does a duty cycling refers to?
Duty cycle is a measure used to describe the symmetry of a square wave and refers to the percentage of the time that it spends at high level. For example if you have a 1 Mhz square wave the period will be 1us and if it is at high logic level for 0.5us and low for 0.5us, that will have a duty cycle of 50%.
What is the pulse width duration of a 500-hz digital signal if the duty cycle is 20 percent?
4ms

What is full load current of 20 HP induction motor in delta?
480V about 20A 240V about 40A look at the nameplate duty cycle and efficiencies vary
A rectangular wave has a 60 percent duty cycle and a frequency of 50 Mhz how long is the signal low?
First of all there is no definition of retangular wave. Maybe your retangular is my square wave. and the answer is inconclusive unless you specify the 40% level.
