If some of it leaks to earth, for example through a person, it cuts the power in a fraction of a second. All power point circuits in Queensland rental properties must have one, and newer homes have them on lighting circuits too. Older switchboards with rewireable fuses often have none. We add them to existing boards where we can, fit individual RCBO protection, and quote a [switchboard upgrade](https://www.hanglooseelectrical.com.au/switchboard-upgrades) when the old board can't take them. ## Recent jobs - Deception Bay ### RCBO protection on every circuit Installed individual RCBO protection on all suitable circuits in an existing switchboard. - Kippa-Ring ### Switchboard RCBO and earthing upgrade A Sunday call-out to fit individual RCBO protection to an existing switchboard and upgrade the earthing. - Scarborough ### Tripping safety switch fixed Found the cause of a tripping safety switch, repaired it and tested the circuit.
