<p>A self-contained, plug-in, hand-held device for testing the current carrying ability of the Hot wire (12) and the Safety Ground return (CC) of standard AC outlets (18) which have Hot connection (12), Neutral connection (16) and Ground connection (14). The test circuit device also detects common miswires and open connections in the AC outlet (18) being tested by way of flashing lights (D2, D4, D6) built into the tester circuit device. If the AC outlet (18) is wired correctly and the total resistance of the Hot line (10) and Safety Ground (CC) are below a predetermined limit, only one light "Green" light (D4) meaning "OK" will flash, which use of only one light to indicate everything is properly wired makes the device easy to use even by a user with little knowledge of electrical testing devices and procedures. Various other detection conditions and indications of occurrence are afforded.</p> |
