The MCB detects the excess current flow and immediately breaks the circuit. This can be seen as tripping action of the MCB knob. Previously, this job was done by fuse. These days MCB is more commonly used in low voltage electrical network than fuse. MCB has several advantages over fuse: MCB is more sensitive to current than fuse. It detects any abnormality in the current flow and automatically switches off the electrical circuit. In case of MCB, the faulty zone of electrical circuit can be easily identified.
The Seder Plate usually contains two places for Maror (bitter herbs) which represent the bitterness of slavery. The two places are called Maror and Chazeret. Only certain specific herbs are acceptable for maror, and the most commonly used vegetables are romaine lettuce and horseradish.
