Best Practices for Entering House with SER Cable Exposed1. Conduit with Sealing Gland

Install PVC conduit from the point of entry to the electrical panel. Use a sealing gland where the cable enters the conduit to prevent water from entering. This method provides the best protection against moisture and damage.

2. Weatherhead

Install a weatherhead where the cable enters the house. The weatherhead should be compatible with SER cable and seal tightly around it. This provides good protection from rain and debris.

3. LB with Short PVC Connector

Install an LB (liquid-tight connector) where the cable enters the house. Connect a short piece of PVC pipe (12-18 inches) to the LB that runs into the house. Seal all connections with sealant. This method provides good protection from moisture and provides a way to support the cable.

4. Service Entrance Box with Connector

Install a weatherproof service entrance box where the cable enters the house. Install a connector on the box that is compatible with SER cable. Seal all connections with sealant. This method provides good protection from moisture and a dedicated entry point for the cable.

Additional Considerations

Always use proper cable clamps or supports to secure the cable to the outside of the house. If possible, run the cable at a slight downward slope to prevent water from pooling. Avoid sharp bends or kinks in the cable. Consult local building codes and electrician recommendations for specific requirements.

Avoid: Running the cable directly through a hole in the wall without any protection. Using PVC pipe for the entire length of the run, as it can become brittle over time. Flag for review
