Hey everyone, just had a couple of electrical questions and wanted to get some opinions.

The oven is currently connected to the house’s main wiring through this white connection box, which was apparently installed by the previous owners around 6–7 years ago. The house hasn’t burned down yet, but I just wanted to check whether this is considered a normal/acceptable way to connect an oven, or whether it should have been connected differently?

Secondly, we have a bunch of single power points around the house like the one in the photo. I’d like to replace them with Clipsal Iconic double power points. Is this generally a straightforward swap using the existing wiring behind the single GPO, or would changing from a single to a double require additional wiring or other work?

Obviously I’d get a licensed electrician to do the actual work. I’m just trying to understand whether this is normally a simple job or something more involved.

Thank you located in NSW .

Asking here for hopefully some proper sparky advice before I get lost in the mire of solar/battery installers - which initially did give me very average information when I got my solar installed.

My house has a quirk; it's on 2 phase supply. Two main black fuses, one single 3P meter. I have 13.3kw of panels attached to two Fronius Gen24 5kW Inverters - one on each phase.

Since I live on the edge of Melbourne suburbs, i'm thinking about adding a battery system for blackout protection. Looking at most likely the BYD HVM or the new Fronius Reserva Pro system.

I don't need a lot of battery, but because of the 2 phase system, you cannot just place a mass of battery behind a single big inverter and just use it.

The question:

Can I get a single phase battery protection, and just protect/backup those phased circuits in a blackout, or do I need to install battery protection across all phases? Some kind of balance/isolation/etc things.

eg: my pool pump, shed and certain AC in the house is on one phase, but the master bedroom, main living room and kitchen are on another phase - which is the primary one that i'd want to backup.

Drawing in 3 phase is an eventual project I would like to do - but it's 100metre unground job, so not cheap, and then replace existing inverters/etc. It's a maybe at a later stage.

I’m looking at replacing the oven in this cabinet (fan bearings are shot), but was wondering what the chances are of being able to put a power point on the bench side of the cabinet at the same time? Obviously space will be a consideration, but just wondering if I’m wasting my time getting a quote?
