Overcurrent Protection Circuit
Overcurrent protection circuit
Examples of overcurrent protection devices are many: fuses, electromechanical circuit breakers, and solid state power switches. They are utilized in every conceivable electrical system where there is the possibility of overcurrent damage.
How do I fix overcurrent protection?
The feeder overcurrent protection device must be sized not less than 125% of 184 amperes, So, overcurrent protection device size = 184 amperes x 125% = 230 amperes. According to Section 240-6(a) for “Standard Ampere Ratings of overcurrent devices”, we must select a minimum 250 ampere overcurrent protection device.
What causes overcurrent in a circuit?
Possible causes for overcurrent include short circuits, excessive load, incorrect design, an arc fault, or a ground fault. Fuses, circuit breakers, and current limiters are commonly used overcurrent protection (OCP) mechanisms to control the risks.
