MCPs are intended to provide which type of protection for motor branch circuits?

Explanation:
Motor Circuit Protectors are designed to guard motor branch circuits against the fast faults that can cause serious damage or shock. The essential protections they provide are short-circuit protection, which trips immediately when currents spike due to a fault, and ground-fault protection, which detects current leaking to ground and trips to protect people and equipment. Overload protection is important too, but it’s usually handled by separate thermal devices that respond to sustained overcurrent and heating, rather than the MCP’s primary fast-fault role. So the best fit is short circuit and ground-fault protection for motor branch circuits.
