Buying Guide
- Conductor configuration: Look for three 4/0 AWG conductors with a 2/0 grounding conductor; ensure the cable is rated for 600V or higher depending on your system.
- Material and jacket: Aluminum conductors with rugged insulation are common for SER cables used in outdoor and direct-burial settings; verify outdoor rating and UV resistance if exposed.
- Length and routing: Choose lengths that minimize splices and maximize straight runs from service entrance to panel. Longer runs may require specialized fittings or clamps.
- Code compliance: SER cables must comply with local electrical codes and utility requirements. Confirm gauge and grounding conductor sizing for service size and capacity.
- Installation considerations: Ensure proper strain relief, protection from physical damage, and adherence to conduit or trenching guidelines as applicable.
- Grounding and bonding: The 2/0 grounding conductor size and method of grounding should align with system grounding requirements and local regulations.
- Brand reputation and documentation: Favor reputable brands with clear product specifications and compatibility notes for service equipment, meters, and panels.
