For an average Terraced House ? I can't see what I want to connect through the RCD side of the CU needing anymore than this really ? I haven't got any huge drain devices, not even a Plasma TV.

Thoughts ?
 
A plasma TV is not a big drain :wink:

Does the property have a large kW electric shower?
Are all the kitchen sockets on the RCD?
Is the oven wired via the RCD?

It is possible to exceed 63A in a domestic environment, and even though it might only be a few amps over the 63A load rating of the RCD if this is a regular occurence it could affect the future operation of the RCD with regards to it's earth fault operation or cause gradual breakdown of the moulding of the RCD body through heat damage.
 
Gas Oven coz I hate electric ovens. Shower run direct off the multipoint heater.
I haven't fitted the new CU yet, I'm just trying to get as much info as poss before I start.
I thought that because the freezer is off the Kitchen sockets, it is a bad idea to connect this ring into the RCD ? or have I mis-read some of the great info I have been given off this site ? Probably so knowing me - hehe
 
it is much better to have a separate, non-RCD radial for the freezer.

I also run my microwave, fridge and dual-fuel cooker off non-RCD radials

electric ovens can give nuisance tripping as they get older. it used to be said that microwaves did too but I'm not sure that's still true.

p.s. not all brands land you wiuth a 63A RCD. Some have a 100A or an 80A.

If you go for RCBOs the problem does not exist, though they work out more expensive if you have a lot of circuits to protect.

You do know this is notifiable work?

Again, excellent information for my planning, thanks again John. I know it is all notifiable work, thanks to the info I've got off here.

I should be able to get access to the sockets for the freezer, fridge and microwave, so I may well re-wire them so they're off the RCD when fitted.

Remind me again John, just how much commission do you actually get off the RCBO manufacturers ? :lol:

I just want to make sure I have ALL the relevant information to give to the LABC before I even consider starting. especially since our lass rang me at work yesterday to say that there will be a dno jointer at my place on Monday to c/o the old cutout for a nice new one so I may be contacting them earlier than I originally thought. :)

I will have to see what he is prepared to do ( if anything ) for a few readies re: fitting an isolator for me, upgrading the main fuse or even moving the supply to the opposite wall ( doubtful coz of the old lead cable feed although you gotta ask aye :wink: ).
 
My factory in Central China is turning out RCBOs 24 hours a day. my other factory, in North Korea, makes cartons and labels with all popular brand names on them. The packing plant in Ruislip glues labels onto the parts according to demand.
 
I see what you mean John :lol:
