You turn on the geyser, only to get hot water for your morning shower. After a few seconds, the electricity is turned off. You inspect the electrical distribution board and find that the MCB has tripped. You reset it, try again and it happens again.
Sound familiar?
A geyser operating the MCB/ELCB is more than a nuisance, especially if it occurs on a regular basis. Generally, it is a sign of electrical issue, high current or leakage that needs to be addressed. In some cases, the issue is within the water heater. In other instances, the wiring, grounding or protective device may be the culprit.
It’s important to know the difference because a wrong diagnosis could result in repairs that are not warranted or, even worse, an electrical hazard that goes unrepaired.
So, why does a geyser trip the MCB or ELCB and how do you handle it when it does?
What If a Geyser Trips the MCB/ELCB?
It’s helpful to know what these electrical safety devices do before trying to identify the fault.
MCB and ELCB are sometimes used interchangeably, but they are used to protect against different electrical issues.
MCB: Protection Against Excessive Current
A fuse protects against excessive current. A Miniature Circuit Breaker (MCB) is a device that interrupts the electrical circuit if it detects too much current.
This can occur due to:
- A short circuit in the geyser’s internal circuit.
- Overloaded electrical circuits.
- Faulty wiring or loose electrical connections.
- Heating element that is drawing excessive current.
For instance, if a geyser is connected in a circuit with other high power appliances, the total electrical load could be more than the circuit’s capacity.
The MCB is designed to prevent the wiring from overheating, which could be a hazard.
ELCB: Protection Against Electrical Leakage
ELCB (Earth Leakage Circuit Breaker) is designed to protect against earth-leakage faults.
ELCB is a term used in Indian homes for leakage-protection devices, but in modern installations, this is usually replaced with RCCB or RCBO.
These devices sense the electrical leakage under the operating principles and shut off the power when a fault is detected.
Leakage can occur in a geyser due to the following reasons: damaged insulation, moisture getting into electrical components, or degradation of its heating element.
The main difference is that a normal RCCB does not offer overload and short circuit protection. Must be protected by appropriate overcurrent protection.
What Is Causing Your Geyser to Keep Tripping the MCB?
It’s not always a clear-cut cause. The time of the trip and the condition of the electrical installation can provide some clues.
1. A Damaged Heating Element
The heating element is a device that transforms electrical power into heat. It is installed inside the water heater and needs to be able to endure repeated heating cycles.
With age, this insulation can deteriorate or corrode.
Should the element have an internal electrical fault, it can result in a short circuit or earth leakage.
Some of the common warning signs are:
- The protective device will trip on the start of heating.
- Water heats up very slowly.
- The geyser turns off completely.
- Over time, tripping occurs more often.
A technician may be able to check the resistance of the insulation and the condition of the element to see if it needs to be replaced.
2. Power Outages or Surges and Electrical Short Circuits
Humidity, steam and splashes of water are inevitable in bathrooms.
But it’s not the same when water gets into electrical connections.
Water in the electrical compartment of the geyser can damage the insulation and form a leak path.
This can occur due to worn seals, plumbing leaks or installation issues.
If water is dripping around the electrical connections, turn off the water supply at a safe dry area and have the electrical connections professionally inspected.
Do not touch the geyser or try to open the casing.
3. An Overloaded Electrical Circuit
Imagine a house with a geyser, washing machine and other high power appliances on the same circuit.
The total electrical load could be more than the circuit can safely supply.
Under normal usage, a geyser of 2000W consumes about 8.7 amperes at 230V. Other appliances add to that load.
The MCB can trip if the circuit is under-rated.
The answer is not to just fit a higher rated MCB. Changes must be made by a qualified electrician, who will ensure that the wiring capacity, circuit arrangement and protective-device rating are suitable.
4. Faulty Wiring or Connections
Over the years, electrical connections can deteriorate due to repeated heating, poor installation or from age.
Loose terminals can cause over heating. Damaged insulation may allow conductors to be exposed and the risk of short circuits enhanced.
The geyser may be working properly but the electrical supply system is faulty.
That’s why the replacement of the water heater may not be the answer if the circuit is not checked.
How Does the ELCB Trip When the Geyser Is Turned On?
Leakage protection trips: Concern is typically different from a conventional overload.
For instance, an RCCB will compare the flow of current in the live and neutral conductors. If there is a difference greater than its threshold, it may mean that it is escaping through an unintended path.
Potential causes include:
- Failure of the heating element insulation.
- Water that can cause damage to the electrical components inside.
- Damaged supply cables.
- Wrong connections or wrong neutral wiring.
- Failure of another appliance on the same protection device to function.
A fault may seem to be caused by a geyser, but the fault is actually related to the larger electrical installation.
A trained electrician can isolate the circuits and run the proper tests to determine the source.
If the ELCB keeps resetting, without finding the cause, it is not safe.
Can Hard Water Make a Geyser Trip?
Hard water is found in various cities and residential areas in India.
It has minerals dissolved in it, mainly calcium and magnesium that can form deposits on heating surfaces.
These deposits can over time impact heat transfer and lead to overheating or degradation of heating elements.
But mineral deposits are not the direct cause of an MCB or ELCB tripping.
When a fault occurs that is related, such as the failure of insulation or abnormal current flow, the electrical trip is triggered.
This is a significant difference.
In hard water areas, regular inspection and maintenance of the geyser can help prevent scaling and component deterioration from becoming an issue.
What to Do When Your Geyser Trips?
The best answer is simple: don’t use the appliance until the problem has been diagnosed.
Follow These Precautions
- Turn off the geyser with the dedicated switch if one is available, as long as the switch is dry and safe to reach.
- Avoid repeatedly resetting the MCB or ELCB.
- Look for any visible warning signs, such as water leaks, smoke or external wiring damage.
- If burning smells or abnormal electrical noises are detected, unplug the appliance and do not use it.
- If you have any concerns, please call a qualified electrician or authorized service technician to check.
Never try to test live electrical connections.
Also, do not short circuit an ELCB, RCCB or MCB to enable the geyser to run.
The protective device that keeps tripping is telling you there may be a fault. When that protection is switched off, users may be at risk of electric shock or fire.
How Can the Proper Geyser Design Enhance Electrical Safety?
A water heater should provide more than just a reliable hot water supply. The design and inherent safety measures are also worthy of consideration.
