This weekly report discusses electrical safety devices. It describes three devices: the Earth Leakage Circuit Breaker (ELCB), Residual Current Circuit Breaker (RCCB), and Residual Current Circuit Breaker with Overload Protection (RCBO). The ELCB detects earth leakage current and has a test button. The RCCB protects against leakage, overload, and direct contact. The RCBO combines residual current protection with circuit breaker overload protection. The report discusses using an ELCB for water heater safety and analyzing the circuit in more detail next week.

Weekly Progress
This week I am interested in some breakers or protection that are safty devices use
to protect people from electricity. I found 3 devices.
ELCB[ Earth Leakage Circuit Breaker ] : or the other name “ELB”, it is the device
which can protection of electric shock and detect earth leakage current. The body of
it is as same as safty breaker but it has the difference that is ELCB has a small
botton called “TEST”.
The Principle of ELCB is comparison with 2 line that are input and output current. If
it loss from the system, this device can detect. There are 2 size ; 15mA and 30mA.
For water heater 15mA is appropriate.
RCCB [Residual Current Circuit Breaker] : It used to protect electical in the industial,
high building and house. The advantages are protect leakage current, overload
current, control in closed system and protect human life from the direct contact
RCBO [RCCB with Overload Protection] : protect from electric shock with circuit
breaker inside this device.
ELCB Brand: Kyokoto How does ELCB work?
Engineering Analysis
Strong Point
- The water heater used ELSB for safety.
Week Point
- If we use is we can use easy but it’s very serious because it’s about human life.
Next Week Job
I will learn more about the water heater circuit and the devices that we need to use.
