GMC home charging requirements
Every GMC electric model we cover, with the charger amperage its onboard charger accepts and the circuit that needs. A larger charger will not charge these cars any faster. Where a model's answer changed between years or trims, its page lists each version.
| Model | Years | Charger | Breaker |
|---|---|---|---|
| GMC Hummer EV | 2024-2025 | 80 A | 100 A |
| GMC Sierra EV | 2025-2026 | 80 A | 100 A |
