This power surge must have produced a temperature elevation of ~35°C, bringing the outlet temperature up to ~46°C. I do not recall whether they reported that temperature, or the power (or both?), but anyway, that's how hot it would be. That is easily confirmed by feeling the hose. It would be harder to feel the 5°C temperature elevation. Of course any thermocouple can detect that with absolute confidence. - Jed
