Lost power but NO RCBO tripped

Probably barking up the wrong tree here but those Henley/connector blocks look odd, the wires coming out at least; outer 2 appear to go to the switch fuse, inner 2 to the isolator - would have thought it'd be 2 left, 2 right ,but then I remembered its line & neutral so should it not be a case of 1 & 3 to switch fuse (or isolator) and 2&4 to either the isolator (or switch fuse) as it stands you've got 1&4 used together at the switch fuse and 2&3 at the isolator.

As I say I'm probably wrong but it didn't look right to me.

It doesn't matter, the service connector blocks are just commoning blocks and don't have any specific terminal designations. Whilst it would be nice for each one to be connected in logical order it doesn't make any difference functionally.

The bigger question as far as that isolator is concerned is why the smaller CU has been connected before the DP isolator? The whole point of having a seperate isolator fitted is to be able to isolate the whole installation from the incoming supply.

If you are talking about the small left hand side CU that’s just another isolator for the outhouse CU.

this wasdone so I could stop either CU supply independently. I believe it’s in a meta box because the armoured cabled to be installed properly needs a proper casing to connected onto via a gland.

You have computers that run for 32 days and no UPS ?

Yes I have three servers and NAS. UPS are overrated for what they do and I don’t have mission critical stuff, I can rebuild the entire setup in an hour, it is all automated build and deploy.

Come on dave, think about it…….it's just another isolator doing the same thing for part of the installation...fused down.

Yes I'm talking about the small CU to the left which has been connected before the plastic supply isolator so that you have no single point of isolation for the entire installation, defeating the object of having the plastic isolator fitted in the first place.

You can isolate each CU via their main switch independantly without that isolator,

I'm thinking about it and can't see it.
It's also not fused, that is just a wylex REC2 100A DP switch in a plastic box

no idea mate, I mean I could switch both off and isolating both CU from any supply? The only time I think that would ever need to happen would of changing CU? Which fingers crossed would be never

That's feeding the main CU. Your 'small CU to the left' is isolation for the outhouse....fused, I'll wager.......and I'd sooner have that as isolation than a cheap plastic one.

Yep that one is fused I believe

1) Mrs turned the iron, but no light, so I thought the switch was off, went to turn it on, but it was on You'll be surprised what they will do to get out of doing the housework
2) Kids coming running in saying wifi isnt working This is actually a great way of finding out how many kids are in the house

Not that I know much but have you tried the iron since?
