Apartment Switchboard Upgrade - Balmain
This weeks featured electrical project
Before we started, this was the condition of the switchboard, these are still extremely common, which is scary!
Switchboard prep work
Prep work - We measured up the existing switchboard and marked where the cable entry was to the unit, we then reflected this onto the new plastic enclosure and cut it out. We then assembled the safety switches on the din rail and inserted links.
Switchboard upgrade pre testing
Once the old switchboard was taken down we isolated all the circuits and tested the insulation resistance on the circuit to see if there was any issues before we powered the new unit up.
We require a reading above 1 mega ohm, in this case we were at 97 mega ohms, well above the required result.
