Appeal No. 97-0289
Application No. 08/111,332
The disclosed invention relates to a modular leakage
current detector and interrupter.
Claim 7 is illustrative of the claimed invention, and it
reads as follows:
7. A modular leakage current detector and interrupter
comprising:
a sense module for detecting ground fault currents in
excess of a given value, the sense module including circuitry
to provide an interrupt signal,
a circuit interrupt module mounted remote from the sense
module and interconnected to the sense module to disconnect
power to the machine upon receipt of the interrupt signal, and
a test and control module mounted remote from the sense
module, the test and control module providing a fault signal
to periodically test the operability of the modular leakage
current detector and interrupter.
The references relied on by the examiner are:
Gryctko et al. (Gryctko) 3,812,400 May
21, 1974
Morris et al. (Morris) 4,686,600 Aug. 11,
1987
Claims 1 through 3 and 5 through 8 stand rejected under
35 U.S.C. § 103 as being unpatentable over Gryctko in view of
Morris.
Reference is made to the brief and the answer for the
respective positions of the appellants and the examiner.
