a spring element; and
a TCA solder terminal.
4. The CISD as in claim 1 further comprising:
a boot, wherein the boot is semi-transparent to allow visible identification of the reset cap thereby identifying reset or set status of the CISD.
5. The CISD as in claim 1 wherein the engagement fin comprises a lift ledge for engaging the contact actuator.
6. An interrupting safety device (ISD), wherein the ISD comprises:
a non-conducting contact actuator having two opposite ends;
a left contact blade;
a right contact blade;
a left moveable contact arm affixed to one end of the non-conducting contact actuator, wherein the left moveable contact arm is adaptable to engage the left contact blade;
a right moveable contact arm affixed to an opposite end of the non-conducting contact actuator, wherein the right moveable contact arm is adaptable to engage the right contact blade;
a column reset assembly for engaging or disengaging the non-conducting contact actuator such that the left moveable contact arm is engaged to or disengaged from the left contact blade and the right moveable contact arm is engaged to or disengaged from the right contact blade, wherein the column reset assembly comprises:
an engagement fin adapted to engage and reset a solenoid pin when the column reset is depressed; and
an engagement fin, wherein the engagement fin comprises a surface adapted to maintain continuous contact with the solenoid pin when the column reset is depressed.
7. The ISD device as in claim 1 , wherein the reset column comprises a reset cap adapted to fit within the reset column.
8. The ISD as in claim 7 further comprising:
a boot, wherein the boot is semi-transparent to allow visible identification of the reset cap thereby identifying reset or set status of the ISD.
9. The ISD as in claim 6 further comprising:
a ground pin (GP) connector, wherein the ground pin connector comprises a GP solder terminal adaptable to affixing a ground wire.
10. The ISD as in claim 6 further comprising:
a test contact arm, wherein the test contact arm (TCA) comprises:
a spring element; and
a TCA solder terminal adaptable to affixing a shield connector.
11. The ISD as in claim 6 further comprising logic and resources for actuating the solenoid pin if determining a circuit interruption should occur, wherein the logic and resources comprise a silicon controlled rectifier (SCR) detection circuit.
12. The ISD as in claim 6 further comprising logic and resources for actuating the solenoid pin if determining a circuit interruption should occur, wherein the logic and resources comprise diode bridge rectifier (DBR) detection circuit.
13. The ISD as in claim 6 further comprising a housing wherein the housing comprises a plurality of hand holds adapted for facilitating hand grasping.
14. A safety device comprising:
a non-conducting contact actuator having two opposite ends;
a left contact blade;
a right contact blade;
a left moveable contact arm affixed to one end of the non-conducting contact actuator, wherein the left moveable contact arm is adaptable to engage the left contact blade;
a right moveable contact arm affixed to an opposite end of the non-conducting contact actuator, wherein the right moveable contact arm is adaptable to engage the right contact blade;
a column reset assembly for engaging or disengaging the non-conducting contact actuator such that the left moveable contact arm is engaged to, or disengaged from, the left contact blade and the right moveable contact arm is engaged to, or disengaged from, the right contact blade, wherein the column reset assembly comprises:
an engagement fin adapted to engage and reset a solenoid pin when the column reset is depressed; and wherein the engagement fin comprises a surface adapted to maintain continuous contact with the solenoid pin as the column reset is depressed;
a first silicon controlled rectifier (SCR) for detecting the presence of an arcing condition, said first SCR setting said column reset assembly such that the left moveable contact arm is disengaged from the left contact blade and the right moveable contact arm is disengaged from the right contact blade upon detecting the presence of an arcing condition; and
a diode bridge connecting the first SCR to the circuit opening device, the diode bridge acting to detect the presence of a second arcing condition, said diode bridge setting said column reset assembly such that the left moveable contact arm is disengaged from the left contact blade and the right moveable contact arm is disengaged from the right contact blade upon detecting the presence of an arcing condition.
15. The safety device as in claim 14 wherein the solenoid pin is ejected when the SCR or diode bridge detects the presence of a first or second arcing condition, respectively.
16. The safety device as in claim 15 , wherein the reset column comprises a reset cap adapted to fit within the reset column.
17. The safety device as in claim 16 wherein the reset column comprises:
a boot, wherein the boot is semi-transparent to allow visible identification of the reset cap thereby identifying reset or set status of the ISD.
