How to Install the RAB 350 OR Series Connector
This guide provides step-by-step instructions for the safe and proper installation of the RAB 350 OR Series connector, covering cable preparation, insertion, and torquing procedures. WARNING: Danger of Electric Shock! Installation must be performed by trained installers following all applicable local, state, and national electrical codes, installation standards, and safety rules.
Estimated time: 15m
Tools needed:
Wrench, Wire strippers, Insulating gloves (rated to appropriate voltage)
Supplies needed:
RAB 350 OR Series Connector, Electrical cable
- Prepare the Connector Rocket
Prepare the connector rocket by cutting it at the marked ring if using #12 to 250 kcmil cable. For 300 to 350 kcmil cable, completely remove the rocket. Ensure all unused cable ports are sealed.
- Prepare the Cable Insulation
Measure the required strip length by placing the cable alongside the marking on the connector tower. Strip the cable insulation to the measured length and pencil the insulation. When reinstalling a cable, it must be of the same size or larger than the one removed.
- Insert Cable into Assembly
Insert the prepared cable directly into the rocket or RAB assembly. If needed, loosen the hex bolt to facilitate cable insertion. If installing on an energized main, ensure tap conductors are NOT UNDER LOAD.
- Seat the Cable Conductor
Continue inserting the cable into either the tower (for 300 to 350 kcmil) or the rocket (for #12 to 250 kcmil) until the end of the conductor is visible and touches the window.
- Remove Screw Plug
Remove the screw plug from the connector by pulling its tether.
- Torque the Connector
Using a wrench, torque the connector to the specified values: 120 in-lb for #12 to #3 AWG cables, and 240 in-lb for #2 AWG to 350 kcmil cables. Refer to the inside of the tether for exact torque specifications.
- Replace Screw Plug
Replace the screw plug into the connector opening.
- Verify Final Assembly
Inspect the finished assembly to ensure the cable is securely connected and the screw plug is properly replaced. Ensure all unused cable ports are sealed.
