Get rid of it at once. Standard amp draw for a circuit breaker is 20A or more (check your breakers for the exact number, it is printed on). Your power supply should not be drawing anywhere near this much. That much current probably means it failed to a short circuit. 120V * 20A [lower limit of current draw] = 2400 watts. An MCB is a Miniature Circuit Breaker designed to protect an electric circuit from overload or short circuit. MCBs have all but replaced fuse wires as a safety measure to protect an electric circuit from over-current because they are safer and come with the advantage that they are reusable. Older Fuse wires were designed to melt and break the

If your power is out in one room but the circuit breaker has NOT tripped, here’s what to do…. 1. Identify where you’ve lost power. The first thing you need to do is work out where you’ve lost power. If it’s lighting, check all of the light switches in the room. If it’s sockets, check every socket in the room. Once you’ve checked

The most significant difference between an MPCB and an MCCB is that the MPCB is most suitable for protecting electric motors from short circuit, overload, under voltage fault and phase loss fault, while the MCCB is a general-purpose circuit protection device that protects a circuit from short circuit and overload faults.
We commonly use MCB for home wiring and also for safety purposes. Types of MCB AC MCB; DC MCB; Generally 16A, 32A, 64A. Rating in the market This is commonly used for light fan cooler TV 16A. While MCB like 32A is used for MCB AC geyser heater water pumps of more than 16A. This addition is used for MCB industrial. Difference Between MCB and MCCB
Short-time pickup is adjustable from 1.5 to 10 times the trip unit ampere setting (Ir). For example, a 1000 ampere frame can be adjusted to trip anywhere from 1500 to 10,000 amps. The switch also has an “OFF” position to eliminate short-time pickup and short-time delay. Short-time pickup used for selective tripping.

In American homes today, thermal magnetic circuit breakers are the most common type. These are circuit breakers which utilize two components to detect electrical faults. The first component is an electromagnet that is sensitive to large surges in electrical currents. Electrical surges can cause short-circuiting, which may seriously damage your
