It can work — but run the load calculation before you buy. The EV-ACT5006T is a 48 A charger, and because charging is a continuous load, the calculation reserves 60 A for it: 60% of a 100 A service, before a single other load is counted. Whether your home can feed it at full power depends entirely on what the rest of the sum leaves behind.
Key Takeaways
- At 48 A, the EV-ACT5006T reserves 60 A in a load calculation — 60% of a 100 A service on its own.
- Whether it fits depends on your home’s existing calculated load; light-load homes pass, heavy all-electric homes often do not.
- If the full install does not fit, the same model on a 50 A circuit (40 A charging) or load management usually does.
- Only a licensed electrician’s NEC calculation counts — get it before you buy, not after.
Why 48 A Is the Hard Case for a 100 A Service
The National Electrical Code treats EV charging as a continuous load, so the circuit — and the reservation in the load calculation — is 125% of the charger’s current:
| Charger current | Breaker fitted | Reserved in the calculation | Share of a 100 A service |
|---|---|---|---|
| 32 A | 40 A | 40 A | 40% |
| 40 A | 50 A | 50 A | 50% |
| 48 A (EV-ACT5006T) | 60 A | 60 A | 60% |
A smaller charger asks the same question with a kinder number. The EV-ACT5006T asks it at the maximum — which is why “will it fit?” deserves a calculation for this model, not a guess. Our guide to panel capacity and charger size gives the general patterns by service size; what follows is the same method aimed at one charger and one panel size.
The Sum, in Round Example Numbers
A real load calculation follows the NEC method, works from your panel schedule and appliance nameplates, and belongs to a licensed electrician — our load calculation basics explain that method. But the shape of the answer is easy to see with illustrative numbers. These are round examples, not code values:
- Example home A: existing calculated load 35 A. Add the EV-ACT5006T’s 60 A reservation: 95 A. Under 100 A — the full 48 A install fits.
- Example home B: existing calculated load 55 A, the all-electric pattern with range, dryer and electric heat in the sum. Add 60 A: 115 A. Over the service rating — the full 48 A install does not fit.
Note that the calculated load is a standardised, conservative total, not your meter’s real peak. A panel that has never tripped can still fail this sum, and that is the calculation working as intended.
Your Three Outcomes With This Model
| Calculation result | What you install |
|---|---|
| Fits at 60 A | The EV-ACT5006T hardwired at the full 48 A, on a 60 A breaker — the complete 11.5–12 kW. |
| Tight | The plug-in version on a 50 A circuit (NEMA 14-50), which under the same 125% rule means charging at 40 A — or load management that trims the charger when the house is busy. |
| Does not fit | A service or panel upgrade first — or a smaller adjustable charger meanwhile, such as the EV-ACS3210T, settable from 10 A to 32 A to match what the panel can spare. |
Two of the three outcomes still end with home charging installed. A reduced-current answer is not a failed purchase: at 40 A the same wallbox still delivers 9.6 kW-class charging, and the upgrade path can be revisited when other electrical work is planned. What a buyer should not do is order the 48 A unit on the assumption that a 100 A panel will somehow cope — the calculation takes an electrician a short visit, and it is far cheaper before the charger is on the wall. EVDANCE’s own guidance is the same: confirm the circuit with a licensed electrician before ordering.
Frequently Asked Questions
Can I run the EV-ACT5006T at 48 A on a 50 A breaker to make it fit?
No. Charging is a continuous load, so a 48 A output requires a 60 A breaker under the 125% rule. On a 50 A circuit, charging current is 40 A. Our breaker sizing guide walks through the pairings.
My panel has empty breaker slots. Does that mean the EV-ACT5006T fits?
No. Empty slots show physical space, not spare capacity. Capacity is what the load calculation totals up, as our guide to charger amps also notes.
Who runs the real calculation?
A licensed electrician. You can estimate with the example method above for planning, but the calculation that supports a permit and the installation is theirs, and they carry responsibility for the result.
