150 Ft 12/2 Submersible Wire

Product: 150 ft 12/2 w/G Submersible Well Pump Wire Cable
Brand: Kalas
Length: 150 ft
Wire Gauge: 12
Conductors: 2 wires plus a ground
The 150 ft Kalas cable provides a straightforward, robust solution for typical shallow to mid-depth wells. Its 12-gauge copper conductors offer solid power handling with reliable electrical resistance. The two hot conductors and a ground wire support standard submersible pump configurations and align with common control box setups. Insulation and jacket materials are designed to resist moisture and abrasion in wet well environments, making it a dependable general-purpose option.
100 Ft 12/2 Submersible Wire

Product: 100 ft 12/2 w/G Submersible Well Pump Wire Cable
Brand: Kalas
Length: 100 ft
Wire Gauge: 12
Conductors: 2 wires plus a ground
This length matches compact or shallow-well installations where the pump and controller are within a shorter reach. The 12-gauge copper conductors support dependable current delivery, while the water-resistant jacket and ground conductor improve safety in damp environments. This option balances cost, length, and performance for routine residential or small commercial wells.
Flat Yellow 12-2/14-2 Cut-To-Length Cable

Product: 12-2/14-2 Flat Yellow Submersible Cable (100′, 12-2) Cut In 10ft Increments
Brand: Kalas
Length: 100 ft (cut in 10 ft increments)
Conductor: 12-2
This option offers customization with 10-foot incremental cuts, providing flexibility for precise pump-to-controller layouts. Rated for 600V, the THW-type wiring delivers durable performance in submersible and external pump installations. The flat, yellow jacket aids visibility and ease of handling during installation, particularly in tight spaces.
100 Ft 12/3 Submersible Wire

Product: 100 ft 12/3 w/G Submersible Well Pump Wire Cable
Brand: KALAS
Length: 100 ft
Wire Gauge: 12/3 + ground
Highlights: Four-wire system for enhanced control and safety
The 12/3 configuration supports more complex pump setups, including additional control lines or a separate ground lead. The plus-ground design ensures safety, especially in wet environments. This length and gauge pair well with mid-sized wells and systems requiring an extra conductor for monitoring or control features.
200 Ft 12/3 Submersible Wire

Product: 200 ft 12/3 w/G Submersible Well Pump Wire Cable
Brand: Kalas
Length: 200 ft
Wire Gauge: 12/3 + ground
At 200 feet, this option covers longer well runs or locations where the pump is farther from the electrical panel. The 12/3 configuration includes an additional conductor for advanced control, measurement, or safety features. The solid copper conductors deliver consistent current, and the jacket is designed to withstand exposure to moisture and potential abrasion in outdoor or underground installations.
Buying Guide: Key Purchase Considerations for Submersible Pump Cables
- Conductor Count and Function: Determine whether you need 2-wire (live and neutral with ground) or 3/4-wire configurations for control circuits and safety. More conductors offer additional monitoring and flexibility for complex pump systems.
- Wire Gauge: Common options are 12 AWG for residential and light commercial use, with 10 AWG offering lower resistance for longer runs or higher power demands. Heavier gauges reduce voltage drop over long distances.
- Voltage Rating and Insulation: Look for cables rated at 600V for submersible pumps. Insulation that resists moisture, oil, and abrasion extends the life in damp well environments.
- Temperature Range: Ensure the cable can operate reliably in outdoor or underground settings with temperature ranges from cold to hot extremes typical of well installations.
- Durability and Jacket Type: A rugged jacket that resists water intrusion and physical damage is essential for submersible and surface-well configurations. Consider flat jackets for easier routing in tight conduit spaces.
- Length and Flexibility: Choose lengths that minimize splices and reduce voltage drop while fitting the physical layout between the pump, control box, and power source. Consider pre-cut vs. customizable options for precise planning.
- Code and Listing: Use UL-listed or equivalent certified cable designed for well and submersible applications to meet safety and code requirements.
- Installation Considerations: For wet environments, ensure proper seals, strain relief, and protection against moisture ingress at connection points. Properly rated connectors and weatherproofing are essential for long-term reliability.
- Cost vs. Longevity: While premium cables may cost more upfront, the higher insulation quality and durability can reduce maintenance and replacement costs over time.
