Dear All

Thanks for the comprehensive replies and also glad that you cleared up
that radial circuits are OK with more than one connection to an MCB. I
have very large MK boards but like to spilit up lighting circuits etc
so blowing bulbs don't take out whole floors.

I'm gald there was agreement that this MCB arrangement wasn't a code 1
risk "requires urgent attention, the safety of those using the
installation may be at risk"

In one property we have spare ways and the NICEIC electricians will add
an MCB and in the other property 2 joint boxes (which are accessable)
will be added.

BTW, yes John, I do have a £ 430 Seaward PAT testing machine and a
Megger so now PAT test my own properties - after all this is UK DIY!!

Thanks - Lightman
