Electrocution Experience: Analyzing Current, Voltage, and Possible Consequences

Best answers

What current and risk were likely involved when I touched a live cooker top and got a strong electric shock?

It was probably a 240 V AC mains shock, not the full short-circuit current through your body, and the current through you was likely in the tens of milliamps, enough to cause pain and involuntary muscle contraction [#7577262] [#7578018] The shock path was probably from the live cooker top through your hand/body to the grounded refrigerator or another earthed point, which would make it feel much stronger than a normal socket zap [#7578460] The blue-white flash can be explained by an arc/electrical flash and visual-nerve stimulation, and the device that tripped was probably an RCD, not just the main fuse [#7578460] [#7578018] Because the current may have crossed the heart, delayed arrhythmia is possible even if you stayed conscious, so an ECG and medical check were recommended immediately when you still had heart pain or palpitations [#7580850] [#7578018] The forum consensus was that this was a serious shock but not a full short circuit through the body, and the exact current cannot be calculated from the description alone [#7578018] [#7578460]

    Hello,
    Quote:
    Voltage did not exceed 240V

    I wrote that

    U = 240V
    (in UK it is the rated voltage)

    Quote:
    As for the formula where there is 1000, it is the assumed skin resistance, which you probably gave using the lowest possible

    I sprayed the metal top of an electric cooker (with oven) before and when I accidentally touched the top

    actually, on the basis of the above, I assumed the conditions in which human impedance is less than 1000?,

    I am aware that these are only speculations and the results may differ from the real ones, but since my colleague mauzer1 he asked, I answered that.

    electrician = electrician :)
    greetings
    George

    sorry, after rereading the posts above, I realized it was probably not for me, :)

    After all, water is a very good insulator.

    I'm in shock. You killed me with this-to death. You see - distilled a bit like that, but find one in the tap or shower.


    A small water film reduces resistance because it facilitates contact and the flow of current. However, even pure tap water has a lot of resistance and in large quantities is just a more poor insulator than a poor conductor.
    In the past, even water was widely used as a simple insulator in the power industry until better ways were invented.
    But in a small amount, such as sweat on the skin, wet hands after washing - it facilitates paralysis because it displaces air, which is a much better insulator.

    Hello!

    Please note where the author is writing from.
    So there can be no question of activating the RCD switch because it is not installed on the islands in the cooker circuit. And the protection of such a circuit is 32A.
    The author mentioned a flash. So this flash triggered the protection.
    However, what the actual incident looked like, unfortunately it is not known.

    When I take a bath, the heater is on the washing machine right behind the bathtub and it uses the washing machine's socket.
    I wonder if this water heater will fall into my way, will the difference work?

    However, the destruction voltage was created and the destruction current flow between the unprotected ( by an electrician ) a stove to a protected refrigerator.
    What was the fire voltage depends on the power grid (two-phase or three-phase - that's what I saw there).
    Mistakes in this (possibly rented) kitchen:
    - repair of the stove by removing the protection (so that it does not knock out)
    - mutual distance between devices
    - carelessness of the user of electrical devices - that was the second warning.

    Hello!

    The power supply is definitely single-phase with 63A protection.
    And the oven circuit is secured with the value of 32A.
    Therefore, there can be no question of disabling this protection with the current flowing through the body.
    Locating several receivers side by side is no mistake.
    The user also does not need to know what an electrician should know.
    Although, when starting to wash the stove, he should consider what the service switch located near it is for. Unless it hurts to think.
    Nevertheless, depriving a receiver made in the 1st class of protection is an idiot.
    And the same is the situation that one of my colleagues illustrated with the question:

    The topic can go on forever, all the necessary information has already been dropped, besides, this is not a section for such talks.
    I close.

Topic summary

✨ The discussion revolves around an individual's experience of electrocution while cleaning a kitchen, specifically involving a metal electric cooker. The user describes a strong electric shock that caused paralysis and a sensation akin to a blow to the head. Responses from forum members analyze the situation, suggesting that the current was likely between 10-15mA, not a short-circuit current, and emphasize the importance of grounding and the path of current flow through the body. The user was advised to seek medical attention due to potential heart irritation and electrolyte imbalance. The conversation highlights the dangers of working with electricity, especially in wet conditions, and the necessity of using residual current devices (RCDs) for safety.

FAQ

TL;DR: A hand-to-hand 240 V fault typically pushes 10–20 mA through the body—“not more than 20 mA” if you stay conscious [Elektroda, Madrik, post #7578018] That is above the pain/let-go threshold yet below fatal fibrillation for most adults. Why it matters: Knowing the real numbers helps you judge risk and fix wiring before the next shock.

Quick Facts

• UK mains: 230 V ± 10 %, 50 Hz, TN-C-S earthing [IEC 60038]. • 30 mA Residual-Current Device (RCD) must open within ≤ 30 ms [IEC 61008]. • Human let-go current: 6–9 mA (women), 9–15 mA (men) [IEEE Std 80]. • Ventricular fibrillation typically starts at ≈ 50 mA for 0.2 s through the heart path [IEC 60479-1]. • Skin impedance drops from ~100 kΩ dry to <1 kΩ when wet with detergent [Elektroda, Bronek22, post #7582449]

How many amps likely flowed through my body during the stove shock?

Forum diagnostics place the current between 10 mA (painful spasm) and 15 mA (involuntary jump) because you stayed conscious and could release [Elektroda, Madrik, post #7578018] That equals 0.010–0.015 A—far below a household short-circuit, which can exceed 1 kA.

Why did it feel worse than touching a 230 V socket before?

This time the path was left-hand to right-hand via the heart while both hands were wet and one touched an earthed fridge. Wet skin cuts resistance below 1 kΩ, so 240 V drives >10 mA; earlier shocks went hand-to-feet through shoes adding extra tens of kilo-ohms [Elektroda, Anonymous, post #7578460]

What caused the blue-white flash I ‘saw’?

The flash was a retinal response to the current passing near the optic nerve, not an external arc. Users often report momentary white/blue light during head-involved shocks [Elektroda, niutat, post #7578104]

Do I still need a hospital check if I feel OK now?

Yes. Currents as low as 25 mA can trigger delayed ventricular fibrillation or electrolyte imbalance up to 72 h later [IEC 60479-1]. An ECG and serum myoglobin test rule out hidden arrhythmia and kidney injury; several posters urged immediate evaluation [Elektroda, Madrik, post #7578018]

Can heart rhythm problems appear days after an electrocution?

Edge case: ‘silent’ fibrillation can persist for days with minimal symptoms and show only on ECG [Elektroda, Madrik, post #7581201] Medical literature notes late-onset arrhythmia in up to 10 % of low-voltage shock patients [Arnold, 2020].

Is this the same as short-circuit current?

No. Short-circuit current is limited only by wiring impedance and often exceeds 1 kA; shock current is limited by body resistance. You felt 10–20 mA, not thousands of amps [Elektroda, Madrik, post #7578018]

How does an RCD save you, and can it fail?

A 30 mA RCD trips when phase–neutral imbalance exceeds 30 mA for 30 ms, removing power before fibrillation onset [IEC 61008]. Unit failure rates are <1 % annually but rise if never tested—press its ‘T’ button monthly [HSE UK]. Cases of non-tripping exist when wiring bypasses the device [Elektroda, mauzer1, post #7582044]

Does body weight or build change electrocution risk?

Only slightly. Fibrillation thresholds scale with heart size, not overall mass. A 85 kg person still fibrillates at roughly 50 mA through the chest path [IEC 60479-1]. Muscle bulk may delay skin burn yet offers little cardiac protection.

Is tap water a conductor or insulator in electric shocks?

Pure water is insulating; tap water contains ions making it moderately conductive (~1 kΩ cm). A thin film bridges skin pores, lowering contact resistance dramatically, hence higher shock current [Elektroda, Madrik, post #7582563]

How can I test my cooker circuit before the next cleaning session?

  1. Press the RCD test button; power should cut instantly.
  2. Use a socket tester with neon indicators (e.g., Fluke ST240) to confirm live-neutral-earth wiring.
  3. Measure casing-to-earth voltage; anything >50 V means disconnect and call an electrician. Always test with power OFF first.

Quick 3-step: what to do if an appliance ‘tingles’?

  1. Switch off at the cooker isolation switch or consumer unit.
  2. Unplug and label ‘Do not use’.
  3. Call a certified electrician to inspect earth continuity and insulation resistance. Never rely on rubber shoes alone.

What happens if the PE (ground) wire is missing or loose?

Without PE, the metal case can float at full phase voltage. You then become the return path to any grounded object, so even 30 mA can pass through the heart—exactly what happened here after a friend ‘unplugged the ground’ [Elektroda, mauzer1, post #7577133]
