Three-Phase Power Installation in North Shore, Auckland

Three-phase supply is what you need for anything that pulls serious load — workshop machinery, commercial kitchens, large heat pumps, 22kW EV chargers, multi-zone air-con, swimming pool heaters, big spa equipment. We handle three-phase mains upgrades from Vector liaison through to final commissioning: load assessment, application to Vector, mains and meter board replacement, three-phase switchboard supply, and sign-off.

Not every site can go three-phase economically — the distance from the transformer matters, and Vector charges for the mains upgrade where they have to. We do the upfront site assessment, get a Vector quote alongside ours, and tell you the all-in cost before any commitment.
