How to Install Star Teck Cable Fittings (ST250-478 Series)
This guide details the installation of Star Teck cable fittings, including cable preparation and proper sealing. WARNING: Disconnect power before installation. CAUTION: Product should be installed by a qualified electrician in accordance with national and local electrical codes.
Estimated time: 15m
Tools needed:
Hacksaw, Wire strippers, Wrench, Torque wrench
Supplies needed:
Star Teck Cable Fitting, Armored Cable
- Select the Appropriate Fitting
Choose the correct Star Teck cable fitting based on the enclosure and the specific armored cable being used. Refer to the product table in the documentation for appropriate cable ranges and specifications.
- Prepare the Armored Cable
First, determine the required working length of the conductor inside the enclosure or device. Carefully remove a portion of the cable's outer jacket to expose the armor. Use a hacksaw to cut the armor, then trim the outer jacket to achieve the exposed armor strip length specified in the product table. CAUTION: Exercise extreme care to avoid nicking or cutting the conductor insulation during this process.
- Insert Cable into the Gland Nut
Feed the prepared cable through the gland nut opening of the fitting. Push the cable until its armor firmly contacts the internal end stop of the fitting, as illustrated in Figure 3 of the documentation.
- Secure and Seal the Gland Nut
Tighten the gland nut until an appropriate seal is achieved or to the maximum torque specified in the product table. Ensure the bushing seals evenly around the cable's outer jacket and that the cable remains centered within the fitting to obtain an optimal and secure seal, as shown in Figure 4.
