Reading list.

Practical writing from the tools — what we run into on real Melbourne jobs and what it teaches us about the standards behind them. We publish here when there's something worth saying: a wiring rule that catches people out, a switchboard era that hides a surprise, a renovation pattern where the electrical side gets squeezed.

New posts arrive Mon / Wed / Fri through the work week.
