I assume you mean the MCB (miniature circuit breaker) which is the thing with the switch on the front. You have several of these in a row in the Domestic Consumer Unit, which is the box with a bit red lever that turns off everything that distributes the power from the meter to the various circuits.
The MCB trips if the current exceeded a certain amperage (5A normally for lighting).
You also tend to have a single RCD (Residual Current Device) that detects flow of current to earth/ground and is what trips to protect from electric shock.
So the MCB burnt out and the chap put in a new one.
