5-5. Earth Leakage Circuit Breaker and Grounding
Warning: Electric Shock

Do not operate the equipment with wrong adjustment of Earth Leakage relay, to
avoid electrical shock when the relay is not properly set.

Always be sure to stop the engine and repair the corresponding earth leakage
fault when earth leakage circuit breakers operate.
Warning: Fire

Do not ground wiring of earth leakage circuit breakers of the equipment to piping
that contains flammable material.
The equipment includes earth leakage circuit breakers (solidly grounded type) in order to
prevent electric shock. Immediately isolate the electrical circuit if earth leakage occurs due
to insulation failure in devices using the equipment or similar reason.
(1)Three phase 415V / Single phase 240V Earth Leakage Circuit Breaker (ELCB)
The equipment is provided with an earth leakage relay in the Circuit Breaker to detect
any leakage arisen due to faults such as insulation failure of the load while the generator
is running and cutting off the circuit for protection against any accident such as electrical
shock.
The sensitivity current of the earth leakage relay can be adjusted from 30mA to 1,000mA
with duration of 0.04sec to 2.00sec by selecting slide switch located on the front panel of
the leakage relay.
For multiple load connections, set the leakage relay setting to be larger than each
Individual leakage current of each load.

Selection of Sensitivity Current and activation duration
Unscrew the leakage relay cover, and adjust the leakage relay to the required current
and duration.
（
Refer to the following selection table.
）
Default setting is below from factory
Sensitivity current: 30mA
Activation duration: 0.04sec

Operation Check
1) Start the engine (Refer to 9-1).
2) Turn the 3-phase ELCB (lever) to [ON] position.
3) Push the test button on leakage relay. The devise
is found to be normal when the circuit breaker
leakage indication button protrudes and the lever
positions in between [ON] and [OFF].
4) Press reset button to turn off the leakage warning
indicator.
5) Push down the lever to [OFF] on 3-phase ELCB,
then lift to [ON] position to reset the circuit
breaker. The leakage relay will continue to shut
off the circuit breaker once it is activated, until
reset button is pressed or engine is stopped.
