Many homeowners only look for an electrician when the electricity suddenly trips. Sometimes the problem happens when you switch on the water heater, aircond or another appliance. Other times, the main switch trips and you are not sure what caused it. Finding the actual cause is important, especially when the same problem keeps happening.
Main Switch Trips at Home
One common problem we attend to is the main switch tripping at home. You may be watching television, using the kitchen or simply switching on an appliance when suddenly the whole house loses power.
There can be different reasons for this. The problem may come from an appliance, wiring, RCCB, MCB, circuit connection or another part of the electrical system. Instead of simply switching the main power back on, the affected circuit should be checked to find out why it is tripping.
Water Heater Causes the Switch Box to Trip
A common situation is when the electricity trips as soon as you switch on the water heater. You may reset the power and try again, but the same thing happens.
The problem may be related to the water heater itself, the heater switch, wiring, RCCB or the circuit supplying the water heater. Tronica can check the water heater circuit and related electrical points to help find the actual cause.
If the water heater switch is old, damaged, loose or shows signs of overheating, it may also need to be replaced. Using a suitable and good-quality water heater switch is important for a high-power appliance.
Water Heater Electrical Check
If your water heater is not working properly, the problem is not always the heater itself. There may be no power reaching the heater, a faulty switch, a problem with the wiring or an issue with the protection device.
We can check the electrical supply to the water heater, the switch, wiring and related circuit. If the heater itself appears to have a problem, we can also advise you to have the appliance checked by the appropriate service provider.
Proper Electrical Troubleshooting
When checking an electrical problem, we do not simply open the switch box and test one point. Depending on the problem, we use suitable testing tools such as a multimeter and electrical tester to check the electrical supply and affected circuits.
We can check the main switch, DB box, RCCB, MCB, switches, sockets, wiring and other related points. This helps us understand whether the problem is coming from the appliance, wiring, circuit or electrical protection device.
DB Box Upgrade in Setia Alam
Some homes have an old DB box that has been in use for many years. As more air conditioners, water heaters, kitchen appliances and other electrical equipment are added, the electrical system may need to be reviewed.
A DB box upgrade may include replacing old components, improving the arrangement of the circuits and checking the protection devices. The actual work depends on the condition of the existing DB box and electrical system.
RCCB Replacement
The RCCB is an important safety device in the electrical system. If it is old, faulty or keeps tripping, it should be checked instead of simply resetting it every time.
Tronica can inspect the RCCB and related circuits. If replacement is needed, we can install a suitable RCCB based on the existing electrical system and requirements of the property.
MCCB & Electrical Protection
For larger electrical installations, the protection device used may be different from a typical home circuit. Some homes with higher electrical requirements, shops and commercial premises may have different electrical protection arrangements.
Where an MCCB is required, we can assist with the related electrical work and recommend a suitable good-quality brand based on the installation. The correct rating and type are important, rather than simply choosing a bigger breaker.
Good Quality Water Heater Switches
Water heaters use a relatively high amount of electrical power, so the switch and wiring should be suitable for the appliance. A loose or poor-quality switch can become hot and may cause problems over time.
If you are replacing an old water heater switch, we can help install a suitable, good-quality switch and check the wiring and connection at the same time. If there are signs of burning or overheating, the cause should also be checked instead of only changing the switch.

Single Phase & Three Phase Electrical Work
Tronica handles both single-phase and three-phase electrical work. Most residential properties use single-phase electricity, while some larger homes, shops, offices and other premises may have three-phase electrical systems.
We can assist with electrical repair, troubleshooting, wiring, DB box work, lighting, power points and other electrical requirements for both systems. The work required depends on the existing installation and the electrical load of the property.
When Should You Call an Electrician?
You should consider having your electrical system checked if:
- The main switch keeps tripping
- The electricity trips when you switch on the water heater
- The water heater switch becomes hot
- You smell burning around a switch or socket
- The RCCB trips repeatedly
- The DB box is very old
- A power point has no electricity
- Lights flicker or suddenly go off
- An aircond causes the electricity to trip
- You need to add more power points
- You are renovating an older house
- You need to replace an old water heater switch
- You need a DB box or electrical protection upgrade
If the same electrical problem keeps happening, resetting the switch may only bring the power back temporarily. It is better to find out why the circuit is tripping before the problem becomes more serious.
