What you can and cannot do during the circuit breaker period· From 7 Apr 2020, Singapore entered the circuit breaker period, in order to pre-empt escalating COVID-19 infections. During this time, Singaporeans are advised to stay home as much as possible. In tandem with the circuit breaker, a new law [the COVID-19 (Temporary Measures) Act 2020] was passed in Parliament on 7 Apr.
How Circuit Breakers Work | HowStuffWorks power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the circuit, the hot wire, leads to the power plant.The other end, called the neutral wire, leads to ground.Because the hot wire connects to a high energy source, and the neutral wire connects ...
