Issue with power cable and PSU connector.
Do you really understand the temperature needed to melt metal? The melting point of steel is between 1371 and 1540°C, while copper melts at around 1,085°C. All the plastic in the cord’s socket would be completely melted and burned if it were true. Since it hasn’t melted yet, there’s no melted metal here. Please review mariushm’s advice. Use a new cable.
The UPS receives its recharge power from the wall outlet. There’s no indication of an issue with the socket itself.
Do you understand how a UPS functions? It contains a battery that maintains operation during power outages. The battery must be recharged after use. How do you accomplish this? Simply connecting it to the wall outlet? If it operates correctly from the UPS, plugging it directly into the wall should work as well. In short, switch the power cord and test the system.
Because it functions isn’t enough; failure indicates an issue. Luckily the ups managed to protect itself. Cord definitely needs replacement. If a warranty repair exists for the ups, it should be considered, especially if you plan to resell or sell it—people will likely dismiss it when they notice the scorch mark.
The UPS wasn’t active during the event, which raises questions about its functionality. Perhaps it’s not working properly. You might want to verify other devices like the toaster, microwave, and doorbell as well.
Hmm? It was or it wasn’t. Was there a way around where the ups appeared in the loop but not fully connected? This makes me think about why an ups was chosen at all. If it weren’t part of the electrical path, there’d be no issues. But if there was a bypass, it would depend on how it was set up. It could have been active, or just present without power. The cable probably shorted, unless the PSU was the first to fail, which then led to the cable shorting. The damaged cable might have burned out the PSU, or the PSU’s shorting caused the problem. The exact cause depends on what’s inside the ups and how it functions. You might want to check with the manufacturer about possible risks.
It didn’t happen; it caught fire. Several cord sockets were emitting enough leakage to ignite without causing a short circuit. Alternatively, poor connection with the power supply socket occurred—still no shorts, just inadequate contact and likely internal arcing.
