why would they need RCBO's, just change the CU spec and juggle with the circuit connections to each way in the CU

I cant see a twin 30mA RCD board being much different to a 100mA S type and a 30mA

yeah fair one but was having problems with two 30ma on a split load as they were intermittently tripping the other one when testing giving odd readings, so reverted back to 16th TT method. Just out of interested was looking back at old 2391 certificate and it said "you have been sucessful in th following "0" modules..." is that correct as doesnt sound very encouraging?

as long as you have the certicate you are qualified

cheers shakey nice one, to be honest am new to the forum, but been reading posts for hours its surprising how much you get other views on things which is great as i work as a stand alone electrician top stuff cant get enough of it!

I agree Ben. M, myself and I get stuck in the same way mode. You think you know/understand something and then someone points out something bleedingly obvious. Thanks for the human conact guys.

I wonder if any of you could help? Have there been any changes in the 17th edition with regards to increasing the size of the neutrals due to harmonic currents?
Any help or advice very much appriciated.

I found a really neat 17th Edition site at 17th Edition Wiring Regulations - Schneider Electric. It's on Schneider's website, but doesn't try to flog you anything. There's a great little interactive quiz on 17th Edition (I only scored 70% so it got me thinking) and some really neat Noddy guides to each of the changed regs.
