A single-phase earth-leakage replacement starts from about R2,250 when testing confirms that the device itself is defective and the board is accessible. The figure combines Wesslink's standard attendance and labour basis with an entry-level registered device from the current price register. It is not a blind swap price: moisture, appliance faults, insulation breakdown, neutral problems or an overloaded device can produce similar symptoms and must be separated first.

Why prices move
Four factors that change the final quote
A better quote explains the variables instead of hiding them inside one number.
Device type
Pole count, current rating, breaking capacity and overload functionality change the component cost.
Cause of tripping
A healthy device may be responding correctly to a downstream fault that still needs diagnosis.
Board condition
Heat damage, loose terminations, mixed equipment or limited space can expand the safe repair scope.
Testing time
Intermittent or multi-circuit leakage takes longer to isolate than a device that fails a controlled test.

Questions people ask
Earth-leakage replacement FAQs
Does repeated tripping mean the earth leakage is broken?+
No. It may be protecting people from a real leakage fault. The device and downstream circuits should be tested before replacement.
Is the device included in the starting price?+
An entry-level single-phase device is included in the stated basis. Premium, combined-overload and three-phase devices are quoted separately.
Can the electrician bypass it temporarily?+
Protection should not be bypassed to keep unsafe circuits running. The safe approach is to isolate the faulty section and repair the cause.
Will replacement stop every trip?+
Only if the device is the confirmed cause. Appliance, circuit, moisture and neutral faults can continue after an unnecessary replacement.
What should I send before booking?+
Send the suburb, a clear safe photo of the DB board, the tripping pattern, recent changes and which appliances or circuits are affected.
