Overloaded circuits
Risk of constant tripping or thermal damage when both households draw peak power.
Capacity & Safety
Switchboard upgrades
for granny flat metering.
A granny flat adds significant electrical demand. We upgrade existing switchboards to meet current AS/NZS 3000 safety standards and ensure sufficient physical space for new meters.
The capacity bottleneck
When the old board
can't cope.
Most Sydney homes were wired decades ago for a single household's needs. Adding a granny flat introduces new air conditioning, cooking, and hot water loads that easily exceed the rating of older ceramic fuse boards.
No RCD protection
Older boards lack the life-saving residual current devices (safety switches) now required by law.
Physical crowding
Simply no room left on the DIN rail to terminate the new sub-mains for the granny flat.
Modern compliance
A secure foundation
for the property.
We remove obsolete switchgear and install modern, high-capacity enclosures fitted with advanced RCBOs (combined safety switch and circuit breakers), ensuring the entire site is electrically sound.
Load balancing
Proper distribution of maximum demand across phases and circuits to prevent nuisance tripping.
AS/NZS 3000 rules
Bringing the installation fully up to date with the latest Wiring Rules.
Future proofing
Leaving adequate spare capacity for EV chargers or solar systems on either dwelling.
