Nassau Electrical Supply 4-4-4-6 SER Copper Cable (100FT)
The 4-4-4-6 copper SER design prioritizes higher conductor counts for more demanding service entrances. At 100 ft lengths, this copper option aims to balance robust ampacity with manageable physical size, supporting 100-amp service runs while maintaining copper conductivity advantages for voltage stability.
NASSAU ELECTRICAL SUPPLY 2-2-2-4 SER Aluminum Cable 100FT
This aluminum SER option provides a comparison to copper SER cables, featuring 2-2-2-4 conductors and 100 feet of length. Aluminum typically offers cost advantages and different resistance characteristics. It is essential to verify local code acceptance and applicability for 100-amp service in the installation area.
Nassau Electrical Supply 100′ 2-2-2-4 Copper SER Cable (Alternative)
Availability and variations in copper SER configurations can lead to alternative listings with identical conductor counts but different packaging or supplier details. This option reinforces the copper SER family for 100-amp service installations, offering practical feasibility in representative above-ground trench or meter base setups.
Buying Guide
Key factors when selecting 100 amp SER copper cable include conductor sizing, insulation rating, and the number of conductors per CIV (conductor in voltage) bundle. Copper SER cables provide low resistance, good temperature handling, and stable voltage performance over longer runs. Consider these perspectives:
- Conductor configuration: 2-2-2-4 is common for 100 amp residential service, while 3-3-3-5 or 4-4-4-6 may be chosen for higher load dispersion or longer runs.
- Insulation and jacket quality: Ensure appropriate insulation for above-ground service entrances and outdoor exposure, with suitable jackets for mechanical protection.
- Voltage rating: Most SER cables designed for 600V or higher are appropriate for standard residential service; verify NEC and local code requirements.
- Material comparison: Copper SER offers lower resistance than aluminum, translating to reduced voltage drop and potentially lower heat buildup under load.
- Install environment: Above-ground vs. underground use, wet vs. dry locations, and exposure to physical wear should guide jacket and shield choices.
- Termination compatibility: Ensure connectors, panels, and meter bases are rated for SER copper conductors and the specific conductor sizes used.
- Code compliance: Always verify with a licensed electrician and confirm local amendments that govern service entrance cable selections for 100 amp service.
The included copper-focused products provide a spectrum of conductor configurations, lengths, and amperage applicability. When evaluating your home’s service needs, consider existing panel ratings, anticipated load growth, and the environmental conditions where the cable will reside. For projects requiring copper SER with strict 100 amp capabilities, the 2-2-2-4, 3-3-3-5, and 4-4-4-6 configurations form common baselines, with 1-1-1-3 offering alternative layouts for specific installations.
