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.
The circuit breaker must detect a fault condition; in low voltage circuit breakers this is usually done within the breaker enclosure. Circuit breakers for large currents or high voltages are usually arranged with protective relay pilot devices to sense a fault condition and to operate the trip opening mechanism. Also indicates the status of the circuit breaker (On or Off/tripped). 2  Most breakers are designed so they can still trip even if the lever is held or locked in the on position. 3  This is sometimes referred to as free trip or positive trip operation. 4  Actuator mechanism-forces the contacts together or apart.
