Connector Identification

Identify the Installed Component First

Useful Information

  • Existing connector type, manufacturer, part or model number
  • Cable manufacturer, cable type, conductor size, voltage rating
  • Connector photographs, mating connector or equipment interface
  • Installation location, primary or secondary application

Tip

A clear photograph of the existing connector and cable can assist identification where original documentation is unavailable.

Primary Connector Replacement

High-Voltage Series-Circuit Connections

Selection Should Consider

  • Primary cable construction, conductor size, voltage requirements
  • Connector arrangement, sealing requirements
  • Associated equipment interface, installation method

Notes

If replacement follows cable damage, also assess the cable and associated transformer or joint. The Primary Connector Kit (L-823) may suit installations specifically requiring a compatible L-823 arrangement, once project requirements are verified.

Secondary Connector Replacement

Transformer-to-Fixture Connections

Selection May Depend On

  • Transformer interface, secondary cable or lead construction
  • Connector configuration, fixture connection
  • Insulation requirements, sealing, physical dimensions

Product

Consider the Secondary Connector Kit where a compatible transformer-to-fixture connection needs replacement.

Secondary connectors are also covered by AC 150/5345-26E (a different class and style from the primary connector), so check the marking on the installed connector rather than assuming it matches the primary type.

Caution: the secondary side is not safe to disconnect while the primary circuit is energised. With the secondary open, the transformer can develop a high open-circuit voltage. De-energise and lock out the series circuit first.

Cable Compatibility

Consider Connector and Cable Together

Important Parameters

  • Cable construction, conductor size, insulation arrangement
  • Voltage class, cable diameter
  • Termination method, connector dimensions, sealing arrangement

Caution

A connector that appears physically suitable may not suit a particular cable construction or electrical application.

  • Maintenance-driven upgrades

Benefit

Compatible replacement components maintain consistency across the existing series-circuit installation.

With Transformer or Cable Work

Review Connections Together

Transformer Replacement

Inspect the associated primary and secondary connectors at the same time. Replacement may reveal damaged connector bodies, deteriorated sealing, cable damage, incorrect legacy connectors or worn secondary connections. Replacing them in the same activity can avoid later access.

Cable Work

Where primary cable is repaired, extended or replaced, review the connector arrangement with the cable; it must suit the new cable construction and conductor size.

Useful Records

  • Connector type, part number
  • Cable reference, circuit reference
  • Installation location, date of replacement
  • Associated transformer or fixture
  • Installation or maintenance reference

Benefit

Accurate records support future troubleshooting and replacement activities.

Safety

Electrical Safety — Isolation and Lock-Out

WARNING — never open a live series circuit. An open series circuit driven by a constant-current regulator can produce dangerously high voltage. Opening, cutting or disconnecting any part of an energised circuit can cause serious injury or death and damage equipment.

  • De-energise the circuit at the regulator and apply the site lock-out / tag-out (LOTO) procedure before any work
  • Where the circuit must be isolated or shorted, use the series circuit cut-out switch or approved isolation device — not an improvised bypass
  • Verify the circuit is de-energised and the output is isolated before touching conductors, connectors, splices or transformers
  • Work only under the airport's permit-to-work system, using qualified personnel and the manufacturer's instructions
  • Follow the applicable national electrical safety regulations and site procedures
Testing

Test Before the Circuit Is Re-energised

  • Visually inspect the completed connection, sealing and cable entry
  • With the circuit still locked out, check continuity and insulation resistance of the affected section, to the project test procedure and acceptance limits (isolate the regulator and transformers as that procedure requires before applying test voltage)
  • Re-energise through the regulator and check the circuit current at each brightness step
  • Confirm the fixture or transformer served by the connector operates correctly
  • Record the connector type, circuit reference, date and test results in the maintenance records
Standards & Project Requirements

Evaluate the Complete Interface

Where a project specifies an FAA-referenced connector arrangement, verify the specification before procurement and evaluate the connector with the complete cable and equipment interface.

FAQ

Replacement AGL Connector Kit — Frequently Asked Questions

What is a replacement AGL connector kit?

A replacement connector kit is intended for maintenance, repair and refurbishment of existing airfield lighting cable connections. It helps maintenance teams restore reliable field connections where an installed connector is damaged, deteriorated, obsolete or otherwise requires replacement, on both primary and secondary connections.

How do I identify the right replacement connector kit?

Identify the installed component first: the existing connector type, manufacturer and part or model number, the cable manufacturer, type, conductor size and voltage rating, the mating interface, the installation location and whether it is a primary or secondary application. A clear photograph of the existing connector and cable can assist identification where original documentation is unavailable.

What is the difference between primary and secondary connector replacement?

Primary connectors serve the high-voltage series-circuit connections, so selection considers primary cable construction, conductor size, voltage requirements, sealing and the equipment interface. Secondary connectors serve the transformer-to-fixture connection. Secondary connectors are also covered by AC 150/5345-26E, but in a different class and style from the primary connector, so check the marking on the installed connector rather than assuming it matches the primary type.

Can a connector be chosen by appearance?

No. A connector that appears physically suitable may not suit a particular cable construction or electrical application. Consider cable construction, conductor size, insulation arrangement, voltage class, cable diameter, termination method, connector dimensions and sealing arrangement together.

What else should be inspected when a connector has failed?

Also inspect the cable insulation, cable sheath and conductor condition, the transformer connection, the fixture connection, any joint or splice, and signs of moisture ingress or mechanical damage. If damage extends beyond the connector termination, a suitable cable repair or Joint / Splice Kit may also be required.

Should connectors be replaced during transformer or cable work?

Yes, review them together. When a transformer is replaced, inspect the associated primary and secondary connectors at the same time, since replacement may reveal damaged connector bodies, deteriorated sealing, cable damage, incorrect legacy connectors or worn secondary connections. Where primary cable is repaired, extended or replaced, the connector arrangement must suit the new cable construction and conductor size.

Can a connector be replaced on an energised circuit?

No. An open series circuit driven by a constant-current regulator can produce dangerously high voltage. The secondary side is also not safe to disconnect while the primary circuit is energised, because with the secondary open the transformer can develop a high open-circuit voltage. De-energise and lock out the series circuit first, and work under the airport permit-to-work system. See the electrical safety warning on this page.

What tests are needed before the circuit is re-energised?

Visually inspect the completed connection, sealing and cable entry. With the circuit still locked out, check continuity and insulation resistance of the affected section to the project test procedure and acceptance limits, isolating the regulator and transformers as that procedure requires before applying test voltage. Then re-energise through the regulator, check the circuit current at each brightness step, confirm the served fixture or transformer operates correctly and record the results.

Can existing cable be kept while connectors are renewed?

Yes. Replacement connector kits can support rehabilitation where the cable is retained and the connections are renewed, and compatible replacement components maintain consistency across the existing series-circuit installation. Where an existing mating component is retained, verify its condition and compatibility with the replacement connector, and update the maintenance records.

Which standards apply to replacement connectors?

References include FAA AC 150/5345-26E for L-823 plug and receptacle cable connectors, AC 150/5345-7F for L-824 underground cable, AC 150/5340-26C for maintenance of airport visual aid facilities and ICAO Doc 9157 Part 5 for electrical systems. Follow the airfield lighting system requirements, the airport authority, the project specification and the connector manufacturer installation procedure.

What information should I send for a replacement connector enquiry?

For a compatibility review, provide a photograph of the existing connector and of the cable, the cable type and size, the existing connector marking or part number, whether it is a primary or secondary application, the associated transformer or fixture model and the installation location where relevant.
