Electrical systems are the beating heart of any home or commercial property. But like any system, faults can—and do—occur. While some faults are relatively minor, others can pose a serious safety risk. At Niceic Electricians, we’re trained to spot and fix all fault types across London, quickly and safely.
Here’s an expert breakdown of the most common types of electrical faults you might encounter—and why it’s vital to act quickly when you suspect one.
1. Short Circuits
A short circuit occurs when electricity flows along an unintended path, often due to damaged insulation or exposed wires. This results in a surge of current, which can blow fuses, trip breakers, or even cause fires.
Warning Signs:
-
Burnt smell near sockets
-
Scorch marks
-
Sudden power outages
We detect short circuits using professional test equipment and isolate the fault before it escalates.
2. Overloaded Circuits
Overloading happens when too many devices are plugged into one circuit, causing it to overheat. This is especially common in older properties without modern consumer units or sufficient power distribution.
Symptoms:
We balance loads and may recommend additional circuits for safety.
3. Open Circuits
An open circuit means the current cannot complete its path—often caused by a break in the wiring or a disconnected component. It leads to dead sockets or non-functioning light fixtures.
What to Look For:
Our NICEIC-approved electricians use continuity tests to find where the connection is broken.
4. Earth Faults (Ground Faults)
Earth faults happen when live wires touch the earth or neutral wires, creating a potentially dangerous situation. These faults are often hidden and pose shock risks.
Indicators:
These faults are high-risk and need immediate expert attention.
5. Loose Connections
Over time, terminals and connectors can loosen due to vibrations or ageing. This leads to intermittent faults, power drops, and overheating.
Clues:
Niceic Electricians will tighten, replace, or upgrade terminals to restore safety.
6. Arc Faults
Arc faults happen when electricity jumps between contacts or wires, generating intense heat. They’re a major fire risk and often occur in worn or damaged cables.
Signs May Include:
We inspect and replace faulty cables and fittings as needed.
Why Electrical Faults Must Be Professionally Diagnosed
Many faults can seem similar to the untrained eye. For example, tripping might be caused by either a short circuit, overload, or earth leakage. At Niceic Electricians, we use calibrated diagnostic tools to test each component of the electrical system. Our NICEIC-accredited engineers guarantee full safety and compliance for domestic and commercial clients alike.
