What’s inside a building switchboard

A plain-language, interactive tour of the switchboard components that come up in every strata EV charging conversation.

When EV charging comes up at a committee meeting, the conversation quickly turns to the switchboard — spare ways, breakers, metering, the incoming supply. This explainer is here so non-technical committee members, strata managers and building managers can follow that discussion with confidence.

Hover, tap or use your keyboard to explore each part of a typical residential switchboard and read what it means for charging. It is a general illustration only, not a depiction of your building.
