Use copper conductors rated above the maximum load to prevent overheating and voltage drop. For standard 16A lines, 2.5mm² cables provide safe current handling, while 4mm² is recommended for 25A circuits.
Install protective fuses or switches close to the main feed to safeguard transformers and downstream modules. Ensure that holders allow easy replacement without disturbing other connections.
Select terminals that match conductor size and current rating. Crimped connectors applied with a ratcheting tool provide consistent contact, while bolted lugs are ideal for high-current junctions. Use heat shrink or insulated boots to cover exposed metal.
Label all input, output, and neutral lines with heat-resistant tags or colored sleeves. Proper identification simplifies troubleshooting, prevents misconnection, and ensures long-term reliability of the system.
Hager Protective Device Connection Guide
Use copper conductors rated at least 20% above the expected load to reduce overheating and voltage drop. For a 16A line, 2.5mm² cable is recommended, while 4mm² is suitable for 25A circuits or higher.
Connect input and output terminals securely using crimped connectors or bolted lugs. Apply consistent torque to avoid loosening under vibration. Cover exposed metal with heat shrink tubing to prevent accidental shorts.
Verify each connection under load with a multimeter before final operation. Measure voltage, continuity, and resistance, and check that protective devices trip correctly. Proper testing ensures safety and long-term reliability of the installation.
Selecting Conductors and Terminals for Hager Protective Devices
Choose copper conductors rated above the maximum expected load to prevent overheating and maintain stable voltage. For 16A lines, 2.5mm² is recommended, while 4mm² is suitable for 25A or higher current paths.
Use connectors that match the conductor size and current rating. Crimped terminals provide reliable contact when applied with a ratcheting tool. Bolted lugs are better for high-current junctions. Always cover exposed metal with heat-resistant sleeves to avoid shorts.
Verify compatibility of all connection points by checking torque specifications and ensuring that the protective devices fit securely in the enclosure. Proper selection and installation of conductors and terminals ensures safety and consistent operation under load.
