<P>PROBLEM TO BE SOLVED: To provide a breaker actuation prevention system which can supply a plurality of power tools with power at the same time from the same power system thereby driving it, and also to eliminate the use of a specified plug socket which has a mechanism where priority is determined in advance, and besides to prevent the errors in processing and the drop of accuracy in processing of a work accompanying the break of a power breaker. <P>SOLUTION: This system includes a current detector 21 which detects a current I1 which flow to a power tool 4 such as a circular saw, etc. other than an air compressor 1 connected to the same power system 60b. A control circuit 12 for the air compressor 1 is constituted to stop the supply of the drive current flowing to the air compressor 1 or to drop the current value so that it may not get over the break current value (for example, 20A) of the breaker 64, based on the output of the detected current I1 of the current detector 21, in case that the air compressor 1 and the power tool 4 have operated at the same time. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
