After a little water damage. I had the opportunity to fit ’ new 3phase SPD DB.

Upgraded the supply from 10mm 4Core - 25mm 5C. New 3phase 100A fused Isolator at the origin. RCBO on each circuit bringing everything up to 18th Edition.
-
Inspection identified that some cables sized were too small for their circuit protection so protective devices downsized for them circuits.
