Some of the symptoms of MLS incude: 1  Small eye. 2  Sclerocornea. 3  Dermal aplasia. 4  Midfacial hypoplasia. 5  Linear erythematous skin lesions.
Best Answer: A. GFCI is the correct answer. Ground Fault Circuit Interruptor: This will open the circuit when a difference in current is detected between the hot and neutral wires in a 120VAC (House current) circuit. B Circuit Breaker will only open the circuit on the hot side when a maximum current is reached. C. Blows open when a maximum current is reached in one line.
During the flowing of current from one contact to other the path becomes so heated that it glows. This is called arc. Arc in Circuit Breaker Whenever, on load current contacts of circuit breaker open there is an arc in circuit breaker, established between the separating contacts. As long as this arc is sustained in between the contacts the current through the circuit breaker will not be interrupted finally as because arc is itself a conductive path of electricity.
