EV charging (residential)
EV charging in new homes: what NCC 2025 requires builders to install at the rough-in stage, and why skipping it costs more later.
Ask Chalkline about this →EV charging (residential) refers to the electrical infrastructure needed to charge an electric vehicle from a home’s power supply. Under NCC 2025 (adopted in most states from 1 May 2026), every new Class 1 building with at least one car parking space must include a dedicated single-phase 32-amp circuit from the main switchboard to the parking space, terminated at a 15A general-purpose outlet labelled for EV charging. The switchboard must also carry spare circuit-breaker capacity: 4 empty slots for all-electric homes, 8 slots for gas/electricity-combination homes.
The requirement is about pre-provisioning. The circuit goes in at rough-in stage alongside the standard electrical package. Retro-fitting after lock-up costs significantly more than the roughly $350 installed during construction.
