RCBO rating needed?

[Siffolkuk]

Hi I’m looking for some advice on what size/rating rcbo I should have installed for a radial circuit which will be running 2 washing machines 2 tumble dryers and steam iron and steam press all domestic appliances and possible all running at a single time ? I’ve been told conflicting info and would like a professional answer if possible
Thanks in advance

What is the total loadings of the items you describe? bearing in mind it is advisable that any fixed load of 2 KW and above should be on it's own dedicated circuit. What answers have you been given, and by whom?

My guess is that this is some sort of fitting out for a small business? Personally, I'd be looking at putting each of those to an individual outlet, probably hardwired to eliminate the plug tops and then each outlet run from a 16A RCBO. Because...... lets assume 2kw per device = 4 x 2 = 8kw + say another 2kw for the ironing = 10kw = 43A @230V And why put all your eggs in one basket?

Sounds like I’ve been told correctly to a point I’ve been advised that I will need a new Consumer board to allow further rcbo,s as it’s a very old unit without much space because as per your advice I’d need split devices onto there own rcbo feeds etc
Thanks for your help much appreciated

Bear in mind that the dedicated circuits can each feed more than one appliance; e.g. three 2kW loads could be connected to one 32A circuit using fused connection units. The important point is that the circuit has sufficient capacity specifically allocated to that appliance, rather than being a general purpose socket-outlet circuit than anything and everything gets plugged into.

If you are taking that approach of hard-wiring the appliances then RCBO's may not be needed at all, it would be possible to design the circuit such that only an MCB is required.

Hard working? Might want a quick edit on that post @davesparks
