Which of the following can occur if the maximum rated load is exceeded on an uninterruptible power supply (UPS)?

A UPS overload condition typically triggers internal protection circuitry such as an overload alarm or bypass mode rather than creating a direct fire hazard during an outage.

UPS units distribute power to all connected outlets simultaneously and do not have logic to selectively cut power to the most recently added device.

A UPS operates from its battery and does not dynamically draw more current from the wall circuit in response to overload - it simply depletes its battery at an accelerated rate.

A UPS battery stores a fixed amount of energy and is rated to supply power for a specific duration at the stated maximum load - when the connected load exceeds this rating, energy is consumed faster than the rated calculations assume. During a power outage under an overloaded condition, the battery will be exhausted well before the advertised runtime, giving little or no time for graceful shutdowns or generator startup. This is the primary and most predictable consequence of exceeding the UPS's maximum rated load.
