I have seen worse in continuing use, at least there are no missing banks. Just proceed carefully as I am sure you normally would. Seeing the incoming and outgoing cables would help.
the 100a thing at the top left is a link to an extension for high current breakers, 80a etc.
its the left/right on/off that stuck out to me.
we are doing fixed wiring testing, and are replacing mismatched breakers with correct ones, just as a matter of course, so this looked really odd when i was checking the schedule as I thought some were turned off.
All hager breakers, but who knows if they are the right sort.
Not sure what you mean, unless it is the fact that some breakers switch on one way while adjacent ones have been put in the other way round so switch on the other way. Not necessarily going to cause a problem but it does mean that if someone has to isolate a circuit they may be switching it on, not off. If they do the right thing and check it is dead they will soon find out (hopefully using a tester and not their finger....)
(Edit: The previous two posts were submitted as I was typing this.....)
Having the RCBOs operating the "wrong" way around is less than ideal and depending on the customer I would either stick massive labels on the board indicating which way is on/off for each switch or replace them. They are the modern Hagar RCBOs. I suspect the original MCBs have been fitted the "wrong" way around. I recently worked on a board similar to yours and they were the other way around.
Actually it looks to me that the RCBOs are the correct way up, and that it's the MCBs which are upside down. Assuming the bus bar runs down the centre.
Consider an RCBO "upright" in a domestic CU. Its base would be be connected to a bus bar and with the load terminals at the top.. Rotate the bus bar and the RCBO 90 degrees clockwise and you get what's in the photo.
