Not an expert but i read a little after you asked the question..
Possibly trip a breaker but otherwise the inrush is very brief. Thats my understanding..

1 - What Is Inrush Current?
Inrush current is also sometimes known as surge current, and as noted above is always higher than the normal operating current of the equipment. The ratio of inrush current to normal full-load current can range from 5 to 100 times greater. A piece of equipment that draws 1A at normal full load may briefly draw between 5 and 100A when power is first applied.
This current surge can cause component damage and/or failure within the equipment itself, blown fuses, tripped circuit breakers, and may severely limit the number of devices connected to a common power source. The following loads will all have a significant inrush current, albeit for very different reasons ...
- Incandescent lamps using a tungsten filament (AC or DC powered, any voltage)
- Fluorescent and other gas discharge lamps (including compact fluorescent types)
- Power transformers, especially toroidal types of 500VA or more
- Power supplies that obtain a low voltage AC from a transformer
- Electronic power supplies, as commonly used for personal computers, wall supplies, etc.
- Electronic power supplies with active power factor correction (PFC)
- Electric motors of all types, with the greatest problems caused when starting under load from rest
- CRT computer monitors and TV receivers. Inrush is deliberately created to operate the degaussing coil(s)
The list above covers a great many products, and with modern electronics infiltrating almost every household and industrial item used it actually covers just about every product available. Few modern products are exempt from inrush current - at least to a degree. Some of the most basic items we use do not have an issue with inrush current at all - most are products that use heating coils made from nichrome (nickel-chromium resistance wire) or similar. The current variation between cold and full temperature is generally quite small. This applies to fan assisted, column and most radiant heaters, toasters and electric water heating elements. Apart from these few products, almost everything else will have a significant inrush current.
In some cases, we can ignore the inrush current because it is comparatively small, and/or extremely brief. A few products may draw only double their normal running current for a few mains cycles, while others can draw 10, 50 or 100 times the normal current, but for a very short time (often only a few milliseconds). Some products can draw many times their normal current for an extended period - electric motors with a heavy starting load or power supplies with extremely large capacitor banks being a couple of examples.
