Fault is any abnormal electric current in power systems. Short circuit occurs when live wire touches neutral or ground. Ground fault allows current to flow into earth. Transient faults clear after short power disconnection. Persistent faults remain present regardless of power application
MCBs protect circuits from 0.5A to 125A, commonly used in residential settings. MCCBs handle up to 1000A, ideal for industrial applications. MCBs have fixed tripping circuits, MCCBs have movable ones. MCBs can have up to 3 poles, MCCBs typically have 4. MCCBs allow remote operation via shunt wires
Short circuit occurs when electricity diverges from established circuit route. Current flows faster through flammable materials and human bodies. Can cause lethal electrical shock through low-resistance pathways
Electric circuit is a path through which current flows. Simple circuit contains source, switch, load, and conductor. Current and voltage are basic features of electric circuits
Short circuit occurs when current flows through low resistance path between terminals. According to Ohm's law, current is directly proportional to voltage and inversely proportional to resistance. Direct connection of terminals with zero resistance creates infinite current flow
Open circuit is a break in electrical current flow. Current cannot flow in open circuits, but voltage exists. Power is zero in open circuits due to zero current. Resistance between terminals is infinite in open circuits
