As a Faultsman, being called out because somebody blew thier pole fuse through over- current and the house fusing never tripped, is a tad worrying and annoying too.
Am I right in believing the electricity entities consider the pole fuse as only a short circuit protection device, NOT an overload protection device. In other words our current installation methods don't include any overload protection device on the consumer mains, such as a main breaker on the switchboard rated to protect the mains. I think there is a proposed change to the next edition of AS/NZS3000 requiring overload protection on consumer mains.(it's too late tonight to check)
