What do you mean by that, you mean the tingling sensation is so strong and sustain that you don't want to touch it? If it is that bad, and that's what I thought based on your answers to my previous questions, then it is definitely not normal.
In North America, we typically consider up to 30 V ac as safe to humans to touch (accidentally..), but don't touch it intentionally for sure. So 10 V is not a problem even if it is real. In your case, I still think it is more likely due to capacitive coupling that could be normal depending on the design, but I would again say it is a bad design if it is more than a few volts, even for phantoms. Not trying to double talk, but on one hand I think your 10 V is just a phantom, capacitive coupling resulted voltage, but then if it is, then I cannot explain why you would get sustained tangling sensation if you keep touching it, that is, without letting go, unless I misunderstood.
Here is an easy to understand wiki article on stray, or phantom voltage due to capacitive coupling that I mentioned before, please read at least the highlighted part:
Stray/contact voltage detection
Stray voltage is generally discovered during routine electrical work, or as a result of a customer complaint or shock incident. A growing number of utilities in urban areas now conduct routine periodic and systematic active tests for stray voltage (or more specifically, contact voltage) for public safety reasons. Some incipient electrical faults may also be discovered during routine work or inspection programs which are not specifically focused on stray voltage.
Equipment used to detect stray voltage varies, but common devices are electrical tester pens
or electric field detectors
, with follow-up testing using a low-impedance voltmeter. Electrical tester pens are hand-held devices which detect a potential difference between the user's hand and the object being tested. They generally indicate on contact with an energized object, if the potential difference is above the sensitivity threshold of the device. Reliability of the test can be affected if the user is at an elevated potential him/herself, or if the user is not making firm contact with a bare hand on the reference terminal of the tester.
is the mechanism used by electrical tester pen devices. Because the capacitance between an object and a current source is typically small, only very small currents can flow from the energized source to the coupled object. High-impedance digital or analog voltmeters may measure elevated voltages from non-energized objects due to this coupling, in effect providing a misleading reading. For this reason, high-impedance voltage measurements of normally non-energized objects must be verified.
Verification of a voltage reading is performed using a low-impedance voltmeter, which usually has a shunt resistor load bridging the voltmeter terminals. Since very little current can flow from a coupled surface through the small shunt or meter resistance, capacitively coupled voltages will collapse to zero, indicating a harmless "false alarm". By contrast, if an object being tested is in contact with a current source, or coupled by a very large capacitance (possible but unlikely in this context), the voltage will drop only slightly as dictated by Ohm's Law. In this latter case, real power is being delivered, indicating a potentially hazardous situation. "
