Hello All, Just a quick question for all the eagle eyed ones among you. The new BYB mentions this 100 and 200 numbering system.  100s are for CENELEC documents and 200s are for UK only.  I can see 200s here and there but no 100s.... Can anyone spot one?

Hello All, I am working away ( as funds and time allow) on the new Irish home.  Anyway, she who must be obeyed wants these new fangled dimmable LED lights in the main rooms and very nice they are too.  My question/ realisation regards circuit protection for these type of circuits.... Here goes...

Hello all, I was on a steel conduit job the other day (remember those?) and did a couple of identical double sets.  I photographed the second in stages to put on my blog.  However, no one ever looks at that so I thought I may pop it here.  If I were to do this, which section would I be best...
