PHOTOBIO Cable Harness, 18AWG, 277V Locking, L7-20P, 10 ft

PHOTOBIO Power Harness — 18AWG, 277V, NEMA L7-20P Locking Plug, 10 ft

This 18AWG PHOTOBIO cable harness with NEMA L7-20P locking plug is designed for facilities running 277V circuits with 20-amp capacity. The L7-20P plug is a step up from the L7-15P in amperage rating, making it appropriate for higher-wattage fixture configurations or installations where a 20-amp locking circuit is the standard.

Like all PHOTOBIO X harnesses, the fixture end uses an IP-rated connector that provides dust and liquid resistance and allows plug-and-play power connection and disconnection at the fixture — no tools, no electrician required at the fixture level. This harness is also compatible with Phantom 60 Series DE 277V fixtures, extending its utility across the PHOTOBIO and Phantom product families.

Key Features & Benefits

• NEMA L7-20P locking plug — 20-amp 277V locking plug — higher amperage rating than the L7-15P, for 20A 277V circuits.
• 18AWG wire — rated for the current draw of PHOTOBIO and Phantom fixtures at 277V operating voltage.
• IP-rated connector at fixture — dust- and liquid-resistant IP connector for plug-and-play power management at the fixture level.
• 10 ft white UV-resistant cable — 10 ft reach with white reflective jacket for maximum light return in the canopy.
• Broad fixture compatibility — compatible with PHOTOBIO CX, MX, T, TX LED fixtures and Phantom 60 Series DE 277V fixtures.

Who Should Use This Harness

Commercial growers with 277V 20-amp circuits running PHOTOBIO CX, MX, T, TX, or Phantom 60 Series DE fixtures who need a locking plug connection at the wall and plug-and-play connection at the fixture.

L7-15P vs. L7-20P — Choosing the Right Locking Plug Rating

Both the L7-15P and L7-20P are 277V locking plugs, but they are rated for different amperage — 15A and 20A respectively. Choose the rating that matches your circuit breaker and receptacle. Using an L7-15P plug on a 20A circuit is safe but wastes the circuit's capacity; using a 20A plug on a 15A circuit is not safe. Always match the plug amperage rating to the circuit rating.

Frequently Asked Questions

What is the difference between L7-15P and L7-20P?

Both are 277V locking plugs, but the L7-15P is rated for 15 amps and the L7-20P is rated for 20 amps. Choose based on your circuit's amperage rating. They are not interchangeable — receptacle slots differ for 15A vs. 20A.

What fixtures is this harness compatible with?

Compatible with PHOTOBIO CX, MX, T, and TX LED fixtures and Phantom 60 Series DE 277V fixtures.

Is this harness compatible with Phantom HPS fixtures at 277V?

This harness is specified for Phantom 60 Series DE 277V fixtures. For other Phantom models, verify the power connector type required before purchasing.

What does the IP-rated connector at the fixture do?

The IP-rated connector provides a dust- and liquid-resistant power connection at the fixture, allowing the fixture to be connected and disconnected from power safely and without tools — simplifying moves and replacements.

How do locking plugs work?

Locking plugs have blades that are angled or shaped so that inserting the plug and twisting it locks it into the receptacle. A counter-twist is required to remove it. This prevents accidental disconnection from vibration or cable movement.
