It simply reads the amount of current going out to a load (a bulb, toaster, drill, whatever...) and the amount coming back. If more is going out than is coming back, it knows that current is going where it is not supposed to, and trips the circuit off.
bulk oil circuit breaker
The best way to determine which circuit breaker is for the water heater is with a voltage meter, It is suppose to be only one circuit breaker, but in a faulty application it could be two breakers
In North America they are known as a GFCI. Ground Fault Circuit Interrupter breaker.
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.
An Earth Relay Circuit Brearker(ERCB is a circuit breaker that senses an earth leak within the system and responds by cutting the power to the appliance or section or giving an alarm pending on the complexity of the system. Most of them can be set to a certain sensitivity, for homes it will be normally 30 mA fixed earth leakage current with an instantanous cut out. For industrial and commercial application the setting can vary pending on the protection needed.
You can test this breaker by clamping it onto the earth cable. This will provide you with the measurements that you need.
the circuit breaker used will be miniature circuit breaker(MCB) maily used in homes.Answer for USA, Canada and countries running a 60 Hertz supply service.A two pole circuit breaker is used for a load of 240 volts. It is sized, according to the load amps of the device, to protect the wires that supply the load current.
