Trip repeats after an appliance is unplugged

Do this first

Your safe boundary

Leave the affected circuit off and do not reconnect appliances, reset the device again or open electrical covers to test a theory.

A repeated trip after one appliance is unplugged may indicate another appliance or fixed-installation fault and is urgent.

No verified cost range is available for this page.

Safety warnings

Danger

Electrical danger

Keep away and warn others. Stop using the affected installation or equipment. Switch it off only if a normal control is safely reachable without approaching exposed parts, water, smoke or fire.

The installation may still be live and capable of causing shock, burns or fire. A switch position, an RCD trip or a simple socket tester does not prove that wiring is safe. Keep the area out of use until a competent electrician has assessed and repaired the fault.

Do now

Warn everyone to stay away from the affected area or equipment.
If a normal switch or isolator is safely reachable without entering the hazard, switch off the affected equipment or supply; otherwise leave it alone.
Leave the property and call 999 if there is fire, smoke, serious injury or another immediate danger.

Do not

Do not touch exposed parts or anyone who may still be in contact with the electrical source.
Do not enter water or a wet area to reach a switch, plug or consumer unit.
Do not remove covers, probe, test, repair or work on live parts.
Do not repeatedly reset a breaker or RCD, or reuse the equipment to see whether the fault returns.
Do not attempt to fight an electrical fire.

Get help

Call 999 for a fire, a person in immediate danger or a serious injury.
After any electric shock, seek prompt medical advice; use 999 if it is an emergency.
Arrange assessment and repair by a competent electrician before the installation or equipment is used again.

Caution

Scheme rules can change

Scheme rules, dates, values and availability can change. Recheck the linked official source before relying on this result.

A dated statement is valid only for its recorded scope and review window. A consultation, announcement or residual web page is not proof that an application route is open. Once review_by passes, quarantine the claim until it is rechecked.

Do now

Check the official scheme administrator or government source and its update date.
Confirm the property, applicant, measure, jurisdiction and application date match the current rule.
Use the earliest review date from every policy record referenced by the page.

Do not

Do not publish a policy claim after review_by without a fresh official-source review.
Do not present a proposal, consultation or future announcement as a current entitlement.
Do not infer budget availability or an open application route from a scheme name alone.

Get help

Use the current GOV.UK or Ofgem scheme page for the relevant programme.
Ask the scheme administrator, obligated supplier or installer to confirm case-specific status in writing.
Suppress the claim if current status cannot be verified.

What is known — and what is not

What is known

Only the page's recorded observations, documents and stated scope are treated as known.

What remains uncertain

The second trip cannot identify which connected load, circuit or protective device is at fault. [1]

Possible explanations

a possible fault in another connected appliance [1]
a possible fixed-wiring fault [1]
a possible protective-device fault [1]

Property decision

Sale: a repeated trip is unresolved safety evidence; do not infer a whole-house rewire or complete fault scope, and retain written findings and completion records. [3]
Letting: for an in-scope rented home in England, the tenant should report the repeat event and the landlord should use a qualified person for required investigation or remedial work. [4]
Next professional: arrange a competent electrician urgently and state that the device operated again after the suspected appliance was disconnected. [1]

What it may mean

The observation may be consistent with a different connected load or a fixed-installation fault; it does not clear the circuit or prove that the first appliance is safe. [1]

What you can check safely

Record the time of each trip and the ordinary equipment that was already in use. [1]
Leave the affected circuit or supply off and warn others not to restore it. [1]
Keep the already disconnected appliance unused and do not reconnect loads to reproduce the event. [1]

When to stop

The repeat trip is already the stopping point: keep away, keep the circuit out of use and do not reset, reconnect loads, remove covers, bypass protection or test live parts. [1][2]

Next step

Ask for written fault findings and any make-safe restriction; do not decide further work before the cause and affected scope are established. [3]

When electrical work must stop

If there is exposed or damaged wiring, arcing, scorching, smoke, a burning smell, repeated trips, electric shock, or electrical equipment in contact with water, keep away and stop. Switch off only if a normal control is safely reachable without approaching the hazard. [2]
In England, Approved Document P says notifiable work includes installing a new circuit, replacing a consumer unit, or any addition or alteration to existing circuits in a special location such as the defined space around a bath or shower, or a room with a swimming pool or sauna heater. [3]
Notifiable work must be certified by a registered competent person, a registered third-party certifier, or a building control body. Do not open, alter or test fixed wiring yourself. [3]
Even work that is not notifiable should still be designed, installed, inspected and tested. A visual check or an RCD trip does not prove that an installation is safe. [3]

Evidence checkpoints

HSE guidance treats RCD operation as evidence of a fault and does not support bypassing protective devices or continuing use after repeated operation. [1]
Evidence date: 2026-08-12
Disconnecting one suspected appliance does not establish that another load or the fixed installation is free from fault. [1]
Evidence date: 2026-08-12
For an in-scope rented home in England, report-required investigation or remedial work must be completed within 28 days or a shorter report deadline. [4]
Evidence date: 2026-08-12
Approved Document P for England lists a new circuit, a consumer-unit replacement, and additions or alterations in a special location as notifiable electrical work. [3]
Evidence date: 2026-08-14

Scope and safety review

This resolved route applies to an England home where a breaker or RCD trips repeatedly or will not remain set, including after one suspected portable appliance is already unplugged.
