פיגורע 1: Illustrative image of a Murray Arc Fault Circuit Interrupter. Note: This image displays a 15-Amp version for visual reference; the product covered by this manual is a 20-Amp model (MP120AFC). The image shows the main body of the circuit breaker, including the toggle switch, the blue 'TEST' button, and various labels indicating specifications like 'MURRAY', 'ARC FAULT', 'AFCI', 'Interrupting Rating 22kA 120V~', and wiring instructions. A coiled white pigtail wire is visible at the bottom.

גיי די סטעפּס פֿאַר געהעריק ינסטאַלירונג:
- מאַכט דיסקאַנעקשאַן: Turn off the main power to the electrical panel at the service entrance. Verify power is off using a voltagE tester.
- אידענטיפיצירן סלאָט: Locate an available slot in the Murray load center.
- Connect Pigtail: Connect the white pigtail wire from the AFCI to the neutral bar in the load center. Ensure a secure connection.
- אינסטאַלירן ברעיקער: Hook the rear of the breaker onto the bus bar stab and firmly push the front of the breaker down until it is fully seated in the panel.
- Connect Circuit Wire: Connect the circuit's hot (black) wire to the terminal screw on the AFCI. Tighten the screw to the torque specified on the breaker label (e.g., 25 lb-in for 60/75°C wire, AWG CU #14-8 / AL #12-8).
- Connect Circuit Neutral: Connect the circuit's neutral (white) wire to the designated terminal on the AFCI, not the neutral bar.
- ומקערן מאַכט: Once all connections are secure and verified, close the panel cover and restore power at the main service entrance.

- To turn the circuit ON, push the toggle switch firmly to the 'ON' position.
- To turn the circuit OFF, push the toggle switch firmly to the 'OFF' position.
5.2 Testing the AFCI
It is recommended to test the AFCI monthly to ensure proper operation.
- זיכער מאַכן אַז דער קרייַז ברעאַקער איז אין דער 'ON' פּאָזיציע.
- Press the 'TEST' button (typically blue) located on the front of the breaker.
- The breaker should immediately trip to the 'TRIPPED' (center) position. This indicates the AFCI is functioning correctly.
- To reset the breaker, push the toggle switch firmly to the 'OFF' position, then back to the 'ON' position.
- If the breaker does not trip when the 'TEST' button is pressed, or if it does not reset, contact a qualified electrician for inspection and replacement if necessary.
6. וישאַלט
The Murray MP120AFC is designed for maintenance-free operation. Regular testing as described in Section 5.2 is the primary maintenance requirement. Keep the area around the electrical panel clean and free from obstructions. Do not attempt to open or repair the circuit breaker.
