the whole C/U is covered by the RCD, what size RCD should be used?
thanks
thanks
Discuss what size rated RCD to use as main switch in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
An RCD used as a main switch should be an S type
i cant begin to tell you the regs you are breaking by using one RCD!!!
Smoke alarm not being on same RCD as sockets?
On a TT system with a split board or if 2x rcd's run in series then yes I agree an S type should be used.
Go on it would help those that dont know. The only one that I can see that might possibly at a push be considered a regs breaker (in a domestic enviroment anyway) is 314-01-01 (i)
Added to that why manufacture cu's with rcd's as mainswitches
Happens all the time on TT supplies. Granted not always on 30mA side but even so the smokes are on an rcd.
a sub board supplying a small number of circuits could have a 30mA and comply.
And 314-01-01??? Regulations with zero's in?? you are SOOOOO 2007!!!!
bonding the bloomin sink in the kitchen
not what sparks who dont know the regs pass off as accepteble work!!!!
As could any of the wylex such as the NHRS1904 (or any other brand) that uses a 100A 30mA rcd as the incomer. Seen as it has 19 ways why not use it for a domestic installation covering all circuits if you so wished (personaly I wouldnt but there you go).
Ok just for you 314.1 (i) or (iv)
Nothing wrong with 16th not untill July 1st anyway.
You mean you dont do this ! JOKING
Yes quite
Once the 17th kicks in you will just have a main switch ten RCBO's for every circuit so that are all individually protected.
Barnsley Council have been speccing split load boards for years.
Main isolator on board is 100mA ,split with a 30mA rcd.

I think SHAKEY needs to write an article about this, I'll try and gather all the true facts and get him to put one together.
