5. Montavimas
This section outlines the general procedure for installing the Eaton GHQ1020 circuit breaker. Always refer to local electrical codes and standards.
- Maitinimo atjungimas: Ensure all power to the electrical panel is OFF at the main service disconnect. Verify with a voltage testeris.
- Prieiga prie skydelio: Remove the electrical panel cover.
- Montavimas: Position the GHQ1020 circuit breaker onto the appropriate bus bar or mounting rail within the panel. Secure it firmly using the bolt-on mechanism. Ensure proper alignment and contact.
- Laidai:
- Connect the load wire (typically black or red) to the load terminal of the circuit breaker. Tighten the terminal screw to the manufacturer's specified torque.
- Connect the neutral wire (typically white) to the neutral bus bar.
- Connect the ground wire (typically green or bare copper) to the ground bus bar.
- Patvirtinimas: Dar kartą patikrinkite visas jungtis, ar jos tvirtai pritvirtintos ir ar tinkamai sujungtos. Įsitikinkite, kad nėra atvirų laidų.
- Skydelio uždarymas: Pakeiskite elektros skydo dangtelį.
- Energijos atstatymas: Atkurkite elektros tiekimą pagrindiniame elektros tinklo atjungiklyje.
6. Operacija
The Eaton GHQ1020 circuit breaker operates as a protective device for your electrical circuit.
- ĮJUNGTA padėtis: Visiškai pastumkite perjungimo jungiklį į „ĮJUNGTA“ padėtį, kad srovė tekėtų per grandinę.
- OFF padėtis: Push the toggle switch fully to the "OFF" position to manually interrupt current flow.
- IŠJUNGTA pozicija: If an overcurrent or short circuit occurs, the circuit breaker will automatically trip to the center position (between ON and OFF). This indicates a fault in the circuit.
- Suveikusio jungiklio atstatymas: To reset a tripped breaker, first move the toggle switch firmly to the "OFF" position, then push it to the "ON" position. If the breaker immediately trips again, there is still a fault in the circuit that needs to be addressed.
7. Priežiūra
