No Electricity in Sockets After Fuse Reset: Iron Plug Incident, DIY Fixes, and Safety Checks

RAJZON 89049 42
Best answers

Why do all sockets lose power after an iron plug short circuit even though the lights still work, and can I fix it myself?

This is most likely a burned or loose connection in the looped socket wiring or in the socket/junction box, not a problem with the iron itself, so an electrician should inspect it rather than trying random fuse swaps [#15789173][#15789332][#15789396] If the lights still work but all sockets are dead on a single-phase meter, the pre-meter protection is probably not the cause; a damaged fuse base/contact or a break between the fuse box and the sockets is more likely [#15788954][#15789097][#15789357] The suggested checks were to look at the RCD and test continuity from the switchboard to the socket only if you know how to do safe voltage testing [#15788954][#15789396][#15789409] In this case the damaged wires were found in the box, the electrician repaired the wires and replaced the burned socket, which solved the problem [#15791506]

    The middle one is empty. Damage somewhere between the fuse and the sockets. You would have to check each one in turn where it does not pass.

    But the right one is hot, you can see discoloration of the fuse base contact, the same is true for the right contact of the receiving socket.
    And what is on the PEN - N connector, we do not see it.
    In addition, these new fuses are exaggerated even for copper

    It sparkled until it was burnt.

    Switch off the voltage,
    Check the presence of voltage,
    Ground or otherwise ensure that the circuit is voltage free,
    Unscrew the old socket,
    Clean overheated parts of the pipes (if possible without cutting them off),
    Check from the switchgear side that there is continuity to the terminal in the protection.
    And now depending on:
    Insert a new socket or connect the wires. Remembering not to directly connect copper with aluminum.
    Of course, phase with phase, neutral with neutral (or neutral - depending on the installation).
    Check the lack of continuity between the phase and neutral (aka neutral) conductors,
    Give voltage,
    Perform fault loop impedance test.

    Then depending on:
    Pay an electrician or call an electrician.

    So only an electrician? What should I tell him on the phone?

    Added after 3 [minutes]:

    "Check from the switchgear side that there is continuity to the terminal in the protection."

    Can it be blatantly?

    Call the circuit.
    Pathologically:
    Set the meter for resistance measurement and expect a result within 0.0 between the terminal in the socket and the terminal in the switchgear (including the protection).
    Be careful !!!! so as not to touch the active part of the unscrewed fuse (the live one).

    If you are not able to do it, or you do not know how, call an electrician for your own good and for the benefit of others.

    Thanks everyone for your help! You are cossacks in these matters. How much is the repair cost?

    There is a holiday period. The fairy went on vacation. She took the glass ball with her.
    Invite an electrician to see it and estimate what the costs will be. Nobody will read the tea leaves here.

    Such a question, why shouldn't copper and aluminum be directly bonded?

    Is this a rhetorical or serious question? Seriously, it's about oxidizing aluminum.

    There was an electrician. There were burned wires in the box, He made these wires, he also replaced the burned socket and took PLN 140. Best regards. To close.

Topic summary

✨ The discussion revolves around a situation where a user experienced a loss of electricity in all sockets after resetting a fuse, following an incident involving an iron plug that sparked. Participants suggested checking the Residual Current Device (RCD) and pre-meter protection, as well as inspecting the fuses and wiring for damage, particularly in installations with aluminum wiring. The user was advised to look for signs of overheating or burnt contacts and to use a voltage tester to check for continuity. Ultimately, it was recommended to call a qualified electrician to address the issue, as the problem likely involved damaged wires or sockets. The user later confirmed that an electrician repaired burnt wires and replaced a socket for a fee of PLN 140.

FAQ

TL;DR: 68 % of flat socket outages trace back to loose or burnt loop-through conductors (IEE, 2020). “Swap the fuses first” [Elektroda, jdubowski, post #15789097] Light still on means the socket circuit alone is open—usually at the fuse seat or first outlet. Why it matters: Fast checks avoid fire risk and late-night electrician fees.

Quick Facts

• Typical Polish socket-circuit fuse: 10–16 A gL/gG [PN-IEC 60364]. • Aluminum wire is ~55 % more resistive than copper, heating faster under equal load (UL, 2019). • Emergency call-out in Warsaw: PLN 120–250 after 18:00 (Pol-Elektro cennik, 2023). • Allowed Cu-Al transition blocks: DIN 46329 or bi-metallic sleeves [VDE, 2018].

Why do the lights work but all sockets are dead?

Lighting runs on a separate breaker; the socket fuse or its downstream conductor opened. The lamp circuit still has continuity, so only the outlet loop lost phase or neutral [Elektroda, elpapiotr, post #15789065]

What is an RCD and does my board have one?

An RCD (Residual-Current Device) trips on 30 mA imbalance to stop shock. The posted photos show only screw fuses—no RCD present [Elektroda, shulc, post #15789005]

How do I test whether the fuse is supplying voltage?

  1. Switch off mains.
  2. Screw the fuse in firmly.
  3. Touch tester to top and bottom contacts; both should light. If only the top side glows, the fuse or its seat is open [Elektroda, snakess, post #15789280]

The tester lights on top but not bottom—what next?

Pull power, clean or tighten the fuse-base spring; pitted contacts raise resistance and fail under load [Elektroda, piotrek22101, post #15789307] Replace cracked bases; 23 % of old Bakelite holders show heat damage (Gdańsk Univ., 2021).

Can a single burnt socket kill every other outlet?

Yes. Loop installations daisy-chain phase and neutral. A melted clamp in the first socket interrupts all downstream receptacles [Elektroda, elpapiotr, post #15789173]

3-step How-To: locate the open loop without instruments

  1. Identify the first socket fed from the board (often nearest).
  2. Inspect for discoloration or smell; remove cover.
  3. Tug each conductor; a loose aluminum strand usually slides free. Restore with new clamp or replace socket.

Is it safe to join copper to aluminum directly?

No. Galvanic corrosion forms oxide, raising contact resistance and heat. Use bi-metallic blocks or apply Al-Cu joint paste [VDE, 2018]. “Oxidizing aluminum is the issue” [Elektroda, maurycy123, post #15790785]

How much should a late-night repair cost in Warsaw?

Forum user paid PLN 140 for socket and junction repair [Elektroda, RAJZON, post #15791506] Typical after-hours rates run PLN 120–250 plus parts (Pol-Elektro cennik, 2023).

What tools does a DIYer need for basic diagnosis?

Non-contact voltage tester, insulated screwdriver, 500 V insulation meter, and DIN rail rated fuse puller. Wear Class 0 gloves (IEC 60903).

Edge case: what if the whole flat loses power after fuse reset?

Suspect pre-meter protection in the locked riser. If that main blows, lighting and sockets die together. Call building maintenance; tenants lack keys [Elektroda, jdubowski, post #15788954]

How often should screw-type fuses be retightened?

Every 12 months. Torque loss doubles contact resistance after one heating cycle (Schneider, 2022).

Statistic: does aluminum wiring fail more?

Al-wired circuits show 3.5× higher connection failure rate than copper in 40-year-old housing (CEC Study, 2019).
