Main Switch Room Sign

Main switch room identification, 600 x 100mm horizontal, carrying the room name and the restriction on unauthorised entry.

Electrical installations are governed by AS/NZS 3000, and switchrooms are among the spaces a building certifier and an electrical contractor both expect to find labelled. The sign has two jobs at once: it keeps people who have no business behind the door from opening it, and it tells an electrician or an emergency responder where the main switch is without opening every door on the floor.

Composite ACM white and silver brushed at $35, satin natural anodised aluminium at $40.

Most buildings need one. The exception is a building where the main switchboard and the distribution boards are in different rooms on different levels, which is normal above about three storeys — in that case the main switch room takes this plate and the distribution rooms take their own, and it is worth signing them differently so that nobody searching for the main switch opens four cupboards first.
