Attach the circuit breakers such as a fuse-free breaker (FFB) or a fuse to the branch
circuit which supplies the electricity to the GR4000. See Table 2.4-4 regarding the
ratings of fuse-free breakers (FFB) or required number of fuse-free breakers/outlets.

*
NOTE: The total electric charge for a branch circuit should be set at 80 –90 % or less of
the rated current
*
NOTE: In order to ease your operation with GR4000, set a distribution panel in the
same/neighbor room where GR4000 is installed.
(3) Considerations when powering a distribution panel
The current capacity of a distribution panel must be greater than that of the operating
current fed to the circuit breaker. (See (2) Distribution Panel.)
WARNING: THE CURRENT CAPACITY OF A DISTRIBUTION PANEL MUST BE GREATER
THAN THAT OF THE OPERATING CURRENT FED TO THE CIRCUIT BREAKER.
IF NOT, THE CIRCUIT BREAKER MAY NOT WORK PROPERLY WHEN A
CIRCUIT ABNORMALITY IS DETECTED. THIS CONDITION COULD CAUSE A
FIRE.
*
NOTE: In general, the operating current fed to a circuit breaker is set to be greater than
the rated current. Check the specification of your circuit breaker before using it.
