Hi all

Just looking for some advice pls. I've been told that I need a new CU as the existing main switch has the wrong rating. Isn't possible to just change the main switch. Existing CU is Marbo.

Many thanks
 
them tails are missing the sheathing outside the enclosure n all..
look, i would just throw a 3 at all this ...but keeping an open mind as to 1s n 2s....
but most of that will tidy up....
theres not enough finals in there to warrent a bigger incomer....or bullit for that matter...

Why not just say it Glen ....... It's an absolute bloody shambles !!!!!

Not like you to be so ....... restrained - are you a bit under the weather?

Tails look like they're probably sheathed reds and blacks to be fair, we've always used them, (well browns and blues now).
Like you say though not even a leccy shower or cooker in sight so no need for a 100A switch.
Whats the betting theres no difference internally between an 80 and a 100 though? just the part number on the front.
 
So, apart from being a mess it aint that bad (those 12yr olds work well for a fiver!!) Glenn, there are blanking plates on the unused ways and there is an earthing block and gas/water are bonded - he checked those. Just the switch he was concerned about and some new meter tails but he could sort all that out without changing the whole unit.

Personally, I see no need to change anything - other than tidy it all up as it looks an absolute abortion of a job.
