Etymology

Origin of overload

First recorded in 1545–55; over- + load

Explanation

To overload is to load an excessive amount in or on something, such as an overload of electricity which shorts out the circuits. Overloading causes a "Too much!" situation. To overload is to push something or someone too far. A supervisor can overload an employee by assigning too much work. People can overload a bus if there are too many of them. A fuse will blow if too many appliances overload the circuits; this is called an overload (the noun form). When something gets overloaded, it usually stops working.
