L-823 Connector Kits
L-823 connector kits are the FAA-specified, factory-molded plug and receptacle sets that join L-824 cable to airfield lighting fixtures and isolation transformers, sealed against water ingress at a below-grade or in-pavement splice point. NLS sources L-823 kits matched to cable size and current rating, supplied as part of the same series circuit package as the cable, transformers, and fixtures.
Inside the L-823 Connector Kits
An L-823 kit is a matched plug and receptacle pair, not a splice, molded at the factory around a set of conductive contacts and sealed with an elastomeric compound so a below-grade airfield connection stays watertight for years.
01
Molded Plug Body
The male half of the connector, molded around the cable end at a factory-controlled dimension so it mates correctly with a receptacle from any qualified manufacturer.
02
Molded Receptacle Body
The female half of the connector, sized to the same cable gauge and current rating as its mating plug so the joint carries load without a heat-generating resistance point.
03
Conductive Contact Pins and Sockets
The metal contacts inside the molded bodies that actually carry the series circuit current, crimped or soldered to the cable conductor during field assembly.
04
Elastomeric Sealing Sleeve
The rubber compound that closes around the mated plug and receptacle, keeping ground moisture out of the connection at an in-pavement or below-grade splice point.
05
Cable Entry Strain Relief
Grips the cable jacket where it enters the molded body, keeping mechanical pull on the cable from working loose the seal or the contact termination inside.

L-823 Connector Kits
| Configuration | Matched plug and receptacle pair, factory-molded |
| Sizing | Matched to L-824 cable conductor gauge and the circuit's series current rating |
| Sealing method | Elastomeric compound rated for below-grade and in-pavement water exposure |
| Compatibility | Mates correctly with L-823 kits from any qualified manufacturer built to the same specification |
| Installation point | Cable to isolation transformer and isolation transformer to fixture connections |
| Field assembly | Requires correct strip length and a clean sealing surface to perform as a watertight joint over years of service |
Every connection point on a series airfield lighting circuit, cable to isolation transformer, isolation transformer to fixture, is made through an L-823 connector kit rather than a taped or heat-shrunk splice, because a below-grade or in-pavement junction on an airfield circuit needs a connection rated to stay watertight and mechanically stable under the flooding, freeze-thaw where relevant, and jet blast vibration a runway or taxiway environment exposes it to over years of service.
An L-823 kit is a matched pair, a factory-molded plug on one cable end and a receptacle on the other, sized to the cable's conductor gauge and rated for the circuit's series current so the connection carries load without a resistance point that generates heat at the joint. The FAA specification defines the physical dimensions, the elastomeric sealing compound the molded body uses, and the electrical rating each size class must meet, which is what allows an L-823 kit from one qualified manufacturer to mate correctly with an L-824 cable end prepared to spec regardless of who terminated it.
Field assembly quality matters as much as kit selection: a connector kit prepared incorrectly, wrong strip length, contaminated sealing surface, incomplete mating, fails as a wet joint months after commissioning rather than immediately, showing up as an intermittent circuit fault that's difficult to diagnose without excavating the connection. NLS supplies L-823 kits matched to the L-824 cable size on the same order and can specify installer training points to the contractor doing field termination, since kit quality alone doesn't guarantee a sound joint without correct assembly.
A project team typically sends cable size and connection count (fixture connections, transformer connections, and any circuit splice points) from the lighting plan, and NLS returns matched L-823 kit counts and a USD quote as part of the broader series circuit cable and transformer package.

Frequently Asked Questions
What is an L-823 connector kit used for?+
L-823 kits join L-824 cable to airfield lighting fixtures and isolation transformers at a below-grade or in-pavement connection point, sealed watertight to a factory-molded FAA specification rather than a field-taped splice.
Why can't a taped splice replace an L-823 connector?+
A taped or heat-shrunk splice doesn't hold the long-term watertight seal a below-grade airfield connection needs under flooding and vibration exposure, and typically fails as an intermittent fault months after commissioning rather than immediately, which is expensive to diagnose without excavation.

Constant Current Regulators (CCR)
A constant current regulator (CCR) feeds a series airfield lighting circuit a fixed current, commonly 6.6A, regardless of how many fixtures are wired into the loop, so every light in the string burns at the same intensity. NLS sources CCR units built to FAA AC 150/5345-10 and IEC 61822, sized to the circuit length a project's lighting plan specifies.
Airfield Lighting Control and Monitoring System (ALCMS)
An ALCMS is the software and control panel platform an air traffic controller uses to switch airfield lighting circuits on and off, select brightness steps, and see live fault status for every CCR and circuit from one workstation. NLS sources ALCMS platforms built to ICAO Annex 14 control requirements, integrated with the CCR equipment already on a project.
Individual Lamp Control and Monitoring System (ILCMS)
ILCMS reports and controls the status of each fixture on a series airfield lighting circuit individually, rather than only the circuit as a whole, so a controller sees exactly which runway light has failed. NLS sources ILCMS field units built to comply with ICAO Annex 14 maintenance and monitoring guidance, for Saudi airbase and heliport lighting circuits.
Series Isolation Transformers
A series isolation transformer connects one airfield lighting fixture to a high-voltage series circuit while keeping the fixture's own wiring isolated at low voltage, and protects the rest of the circuit if that one fixture fails or is disconnected. NLS sources isolation transformers built to FAA AC 150/5345-47 and IEC 61822, sized to fixture wattage and rated series circuit current.
L-824 Airfield Lighting Cable
L-824 is the FAA specification for the cross-linked polyethylene insulated, direct-burial cable that carries series circuit current between the CCR, isolation transformers, and every fixture on an airfield lighting loop. NLS sources L-824 cable in the current-carrying sizes and armour options a project's circuit design and duct or direct-burial routing require, for Saudi airbase and heliport lighting projects.
