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.
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device to quickly disconnect current to prevent serious harm from an ongoing electric shock.Injury may still occur in some cases, for example if a person falls after receiving a shock.esidual-current and overcurrent protection may be combined in one device for installation into the service panel; this device is known as a GFCI (ground fault circuit interrupter) breaker in the USA and Canada, and as an RCBO (residual-current circuit breaker with overload protection) in Europe.
