The independent journal for licensed electrical contractors in Australia
Small commercial three-phase, lighting and energy standards, data alongside power, industrial maintenance contracts and construction-site supplies.
A cheap monthly fee looks like steady work until the first after-hours isolation, the first missing spare, and the first argument about who locked the board. Read the contract as an electrician, not as an optimist, and decide what you are actually selling.

A café, a workshop or a two-tenancy shopfront is still a three-phase installation, and it will punish a contractor who treats it like a big house. Load balance, isolation, the MEN, motors, kitchens and the moment you must call the DNSP are the difference between a clean job and a week of brownout complaints.
Shared trays, PoE cameras and access-control cables are now ordinary on commercial jobs, and so are the defects they leave in a live board. Segregation, fire-rated penetrations, licensing boundaries and a hard rule about who may terminate in a switchboard will keep a data job from becoming an electrical incident.
A cheap LED batten swap can still fail a certifier, an inspector and the people who have to live under the lights. This piece walks through NCC Section J in broad terms, emergency lighting, leftover fluorescent gear, and the paperwork a lighting job actually has to carry.

Construction wiring is a different installation from the permanent one that will replace it, and AS/NZS 3012 is the book that says so. Site sheds, RCDs, generators and the question of who owns the board when the builder moves it are where temporary supplies fail — usually in the rain.
