<P>PROBLEM TO BE SOLVED: To shorten the length of the ground side connection conductor of a Surge Protection Device (SPD) as much as possible to ensure overvoltage protection of a load. <P>SOLUTION: The overcurrent protection apparatus storage board includes overcurrent protection circuit breakers 22, 23 connected to a charge line 21 and an SPD24 which is connected to the overcurrent protection circuit breakers 22, 23 and absorbs a surge current flown from the charge line 21 in a conductive housing 25. A first ground terminal block 32 is installed in the conductive housing 25 with electrically insulated, the SPD24 is connected to the first ground terminal block 32 where a ground bus 31 is connected, using a first ground line 34, a second ground terminal block 35 is installed in the conductive housing 25 with electrically connected, and the SPD24 is connected to the second ground terminal block 35 where a load 27 is connected, using a second ground line 36. <P>COPYRIGHT: (C)2012,JPO&INPIT |
