Do any of the British based electricians know if this is likely to be an Irish version of the UK ring circuit system or radial with fused plugs? Would just like to make an educated guess withouth dismantling the distribution panel.

Relatively modern installation (1970s/80s)

largeish 4 bedroom house

52 socket outlets (BS 1363 switched doubles)

10 X 20 amp MCBs and 2 X RCDs on Siemens board makred sockets.

7 X 5 amp MCBs marked Lighting
1 X 10amp marked low voltage lighting, phone sys, alarm.

1 X 20 amp marked Immersion
1 X 10 amp marked central heating & controls.
1 X 32 amp marked cooker.

There's also an Over-voltage Arrester (presumably lightening protection) and a 63amp Neozed fuse on the board.

Similar to UK specs?
