screwfix or toolstation bg fully populated boards are cheap enough and quality
Well, sort of. Previously compliant set-ups, especially those with RCD protection and pvc cabling, are seldom impacted by new revisions unless or until modification.
Either of these any good?
Lots of them were in the sale but now not available.
I am trying to work out how many rcbo/mcbo? Etc etc and also what amperage etc.
As a minimum I need a lighting circuit.
A 13amp.plug circuit and a welder/ plasma circuit.

No idea, but I think this one looks sexy.

both will do the job depending how many ways are needed
That's what I dont know. Lol

a lighting circuit 6 amp sockets a 16 amp run on 2.5mm cable or 30 amp radial using 4.0mm cable and welder and plasma size depends on the total load which should tell the rating on the machines in full load amps
Either. my thinking an extra spareway or two does no harm.Got no replies last time so asking again.
More details this time.
Which of the two above would be suitable for a garage?
But your choice still might be false economy, the pre-populated type, if the MCBs included suit your needs, your quids in but I gather your not sure of your circuit/load requirements.
In which case would you not be better going down the non-populated, ( except for main switch/MCB ), CU and RCBO route.
Twice as much as budgeted for but occasionally there are some good deals to be had that won't make anyone wince so much.
RCBOs, safer and more future proof in a workshop environment.

why is an rcbo safer than an rcd with mcb .the only advantage the rcbo has is only one circuit fails on a fault and its easier to fault find. ive only ever tripped my garage supply once in 5 years slicing a cable

If the RCD is protecting multiple circuits including the lights and it trips it could introduce a falling over hazard!
Certainly would in my workshop as it has no natural light and clutter everywhere currently!
I am a huge fan of individually protected circuits personally, you only loose that one faulty circuit, also makes fault finding a lot easier.

no different to a powercut. if the lighting circuit has a fault they go off if its so important fit an emegency light.. ive fitted a fair few in electrical cupboards in a school i work at

I hadn't replied earlier I went down with a motherload of a cold, viewing but not replying.
I'm sure I read here or maybe on another site and it was repeated apart from the convenience of RCBO circuit fault finding, in any same give fault a RCBO would trip faster than an MCB?
It's why I said safer.

an rcbo is an rcd with built in mcb a seperate rcd and a seperate mcb is just the same and the tripping times and current of each will be identical so makes no odds which you choose for convinience
