Yes — for the feeder run, aluminium is a normal choice. The long cable from the main panel to a garage or subpanel is where electricians most often propose it. The charger’s own branch circuit is a different run, where copper is the usual default. Which metal goes in is your electrician’s decision, against the ratings on the equipment at both ends and the locally adopted code — never a DIY specification.
Key Takeaways
- Aluminium is a routine choice for long feeder runs; the branch circuit is a separate question, where copper is the default.
- Three things decide it: terminal ratings at both ends, the adopted code, and the electrician’s design.
- An existing aluminium feeder is an inspection case before a charger load is added — not an automatic problem.
- Never extend or tap an old aluminium branch circuit for a charger, and never size a feeder from a guide.
Three Different Runs Get Called “the Wire”
They are three separate runs:
| Run | What it does | Where the metal question sits |
|---|---|---|
| Service and feeder runs | Power to the main panel, and from there to a subpanel or detached garage | The big, long runs — aluminium is a routine candidate here, sized and terminated for the job |
| The charger’s branch circuit | The final run from a panel to one charger | Copper is the default — see our guide to what size wire an EV charger needs |
| Existing aluminium in an older home | Branch wiring fitted decades ago for lights and sockets | Not a material choice — an inspection question; an old aluminium branch circuit is never extended or tapped for a charger |
This article is about the first row: the feeder, where the saving can be real — and whose ends land on rated equipment.
The Three Checks That Decide a Feeder
- The equipment at both ends. Every panel and breaker states which materials its terminals accept. That rating, printed on the equipment, is a hard boundary: an aluminium feeder works only if the terminals at both ends are rated for it, with termination hardware rated for the metal.
- The code as adopted locally. Materials are governed by the code your area has adopted, and the installation is inspected against it. The NEC recognises both metals; it demands one compliant design of conductor, size and terminations.
- The electrician’s design for this run. The feeder carries everything downstream, including the charger as a continuous load — sized under the 125% rule, so a 48 A charger counts as a 60 A load. Length, load and future additions are the inputs; the metal is chosen inside the design.
Notice what is missing: a size. No gauge is stated here, because size belongs to the design above. A source that names a feeder size without knowing your load, run and ratings is guessing with your installation.
If the Feeder Already Exists
Many garages are already fed by an aluminium feeder installed years ago; that alone is not a problem. What changes is the load: full current for hours, every night — a harder duty than most garage loads place on those terminations.
So before a charger circuit is added downstream, the electrician inspects the feeder’s existing terminations at both ends for condition and signs of heat — an on-site judgement on the actual connections. It has no DIY version: assessing terminations is licensed work, scoped from what the electrician finds.
The Charger at the End of the Run
The EVDANCE EV-ACT5006T 48A Level 2 wall charger delivers up to 48 A, hard-wired or via a NEMA 14-50 plug, with a 25 ft NACS cable and IP65/IP66 sealing. At full current it sits on a 60 A circuit, which the feeder design carries as a continuous load. Whether the feeder is copper or aluminium is settled upstream, between your electrician and the ratings; the charger is configured for its circuit either way. See the home range on our residential EV charging page.
Frequently Asked Questions
Is aluminium feeder wire allowed by code?
Aluminium is a recognised conductor material under the NEC. The code requires a compliant whole: a conductor sized for the load, terminals rated for the metal, inspected under the locally adopted code. Your electrician confirms all three.
Will aluminium save money on a long garage run?
The metal usually costs less, and on a long feeder that is worth pricing; fittings and labour narrow the gap. Only paired quotes answer it — the same run priced both ways.
My home already has aluminium wiring. Is that the same question?
No. Older aluminium branch circuits are a separate subject: the charger’s own circuit is new, and an old branch circuit is never extended to feed it. The electrician judges the panel and any connection the new work touches.
