An earth-leakage device that trips is doing an important job, but the trip does not identify the cause. Replacing the device without testing can leave the original fault unchanged—or remove a correctly operating component.
A responsible quotation separates diagnosis from replacement. The electrician should test the device and isolate affected circuits or equipment before deciding what needs to be repaired.
01
Why earth leakage can trip
Possible causes include moisture, damaged insulation, faulty fixed equipment, deteriorated outdoor circuits, neutral-earth faults, connected appliances or a defective protective device. The sequence of events matters.
Record whether the trip occurs during rain, when a geyser or pump starts, after grid restoration or only with a particular circuit energised. Do not bypass the protection to keep power on.
- Time and weather conditions.
- Circuit or appliance operating at the moment of the trip.
- Recent building, solar or inverter work.
- Whether the device resets with final circuits switched off.
- Any heat, odour, water or visible damage.
02
What affects the replacement or repair cost
Cost may include attendance, diagnostic testing, the correct replacement device, labour, related connection repairs and final testing. If the actual fault sits in an outdoor circuit or fixed appliance, replacing the earth-leakage unit is not the complete remedy.
Ask the quotation to identify the tested cause and the exact component or circuit being repaired.
- Electrical fault finding — Evidence-led fault diagnosis.
- Distribution-board repairs — Board testing and corrective work.
03
Why bypassing earth leakage is unsafe
The device is intended to disconnect supply when residual current indicates a potentially dangerous condition. Bypassing, holding or repeatedly resetting it can expose people and property to risk.
If essential equipment is affected, isolate the problem through proper testing rather than defeating the protection.
04
Request diagnosis, not a blind component swap
Tell the contractor that the symptom is earth-leakage tripping and describe the conditions. Ask whether the booking includes systematic isolation and device testing.
This approach produces a more defensible price and reduces repeat visits caused by replacing the wrong item.

05
Create a safe earth-leakage fault record before requesting replacement
An operating earth-leakage device does not prove the device itself is defective. The cause may be an appliance, moisture, wiring damage or a combination of leakage across several circuits.
- Record the time, weather and equipment in use when the trip occurred.
- Unplug portable appliances only where this is safe and accessible; do not open fixed equipment.
- Attempt no more than one ordinary reset and stop if it trips again immediately.
- Note which circuits or appliances appear associated with the trip, without bypassing protection.
- Send photographs of visible labels and describe any moisture, smell, sound or recent electrical work.
Request diagnosis and test results before authorising a component swap. Never bridge out or bypass earth-leakage protection to keep the supply on.
FAQ
Questions readers also ask
How much does earth-leakage replacement cost in Roodepoort?
The total depends on diagnostic time, the correct device, board condition and whether another circuit or appliance is causing the leakage. Testing should come before replacement.
Does tripping mean the earth-leakage breaker is broken?
No. It may be operating correctly in response to leakage elsewhere. The device and installation need testing.
Can I bypass earth leakage temporarily?
No. Bypassing protective equipment can create serious shock and fire risk. Arrange proper fault isolation.
Why does it trip when it rains?
Moisture in outdoor wiring or equipment is one possibility, but testing is required to identify the affected circuit and cause.
