Changing main switch on CU

[watson650]

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

I asked that if it was an issue, couldn't we just replace the main switch with 100A switch. Apparently, that's not possible.

eh?...

Thanks for all your replies. Nice to have confirmation. Shame really, it's not the first job he's done for me.

sounds like he may be pushing for work.

Probably best to get a second opinion as has been suggested, if he's done work for you before then it can be assumed you are happy with him and there maybe an honest reason for him making the statement.

Change main fuse would be easiest thing to do if your that worried about it, what coding did he put it down to? C3? Did he give you a cert saying unsatisfactory? If not just ignore it as next time meter man comes to upgrade meter he will down grade to 60amp fuse more than likely anyway so don't worry about it.

I rang a local electrician the other day, he hasn't been out to look, but pretty much said the same as everyone else on here. Don't think I'll be changing it. Haven't got a copy of the report yet but it doesn't seem to be as serious as he's making out. Funny enough, it would've been his first job after his hols!

Will try and get a photo.

Thanks again

Who cares on an existing install? As long as it's secure and readings are ok.........

ahh those good old conscientious meter men hey? alwsays checking main switch sizes an that, just in case the fuse needs downgrading, sometimes they will even put in an extra socket for you !
