Triple 50A Anderson Plug Extension Lead – Ignition/Trigger Wire for DC-DC Chargers

Overview

This triple 50A Anderson plug extension lead is built for DC-DC charger installs that rely on a triple Anderson (3-pin) connection — positive, negative, and an ignition/trigger wire for the charger’s “vehicle on” signal. It’s the go-to setup for chargers wired to a Smart (variable voltage) Alternator, where the DC-DC unit needs a genuine ignition-on signal rather than reading alternator output directly. If your triple Anderson connection needs to reach further — charger relocated to a canopy, drawer system, or second battery box further from the engine bay — this lead extends it cleanly with matched connectors on both ends.

Key features

• Triple 50A Anderson plug on both ends for a direct extension of your existing connection
• 13mm² (6 B&S) twin core cable carries the positive and negative power circuit
• 4mm² single core cable carries the ignition/trigger wire
• Full-length split conduit sleeving protects all three conductors from abrasion, heat and general wear in engine bays, canopies and under-vehicle runs
• Six standard lengths, with custom lengths made to order

Specifications

What it suits

Designed for DC-DC charger installations using a triple 50A Anderson connection for the positive, negative and ignition/trigger circuit. Suits setups where the DC-DC charger needs to be positioned away from the existing triple Anderson point — dual battery trays, canopies, drawer systems and camper conversions — without splicing or re-terminating the original wiring.

Need a custom length?

Not all installs fit a standard length. If your run falls outside the sizes listed, get in touch with your required length and we’ll quote it made to order.

Australian Made

Made using Australian Made cable, in line with Bluebar’s Australian Made certification. Built to spec, not to a price.

══════════ FAQ ══════════

Q: What is a triple 50A Anderson extension lead used for?

A: It extends an existing triple 50A Anderson connection — positive, negative and ignition/trigger wire — so a DC-DC charger can be positioned further from the original connection point. It’s commonly used where the charger has been relocated to a canopy, drawer system or second battery box.

Q: Why does the lead have a separate ignition/trigger wire?

A: DC-DC chargers paired with a Smart (variable voltage) Alternator need a genuine ignition-on signal rather than reading alternator output directly, since Smart Alternators don’t hold a constant voltage. This lead carries that ignition/trigger signal on its own 4mm² single core conductor alongside the main power circuit.

Q: What cable and connectors does this lead use?

A: The power circuit runs on 13mm² (6 B&S) twin core cable, sized to suit a 50A Anderson connection, with a 4mm² single core wire for the ignition/trigger signal. Both ends terminate in a triple 50A Anderson plug.

Q: What lengths are available?

A: This extension lead is available in 500mm, 1m, 2m, 3m, 5m and 6.5m lengths to suit different install distances.

Q: Is this lead protected against abrasion?

A: Yes. The full length is covered in split conduit sleeving, which protects the cable from rubbing, heat and general wear in engine bay, canopy and under-vehicle installs.

Q: Is this lead Australian Made?

A: Yes. It’s made using Australian Made cable, covered under Bluebar’s Australian Made certification.

Q: Can I get a custom length?

A: Yes. If none of the standard lengths (500mm–6.5m) suit your install, contact us with the length you need and we’ll quote it made to order.
