Blackburn is about 2496 people per square kilometre. The usual job is a straight replacement with RCBOs and proper labelling. At about 98 metres, Blackburn is low and level, and a board replacement is usually a half-day job.
Blackburn is roughly 16 kilometres from the CBD, where boards from the 1970s to the 1990s are the norm and an upgrade is a planned job rather than an emergency. For Blackburn, Whitehorse is not involved. The party that matters is the distributor, and only when the service or metering changes.

We are based in Boronia, about 12.5 kilometres west of Blackburn. Close enough that the person who quotes the job is the person who comes back to do it.
