Just wonder if anybody knows of any electrical factors that tend to carry stocks of older equipment. I have a Crabtree consumer unit, fitted about 8 years ago, and want to fit two new circuits. Speaking to Crabtree, the current MCB's should fit but are not directly interchangable so it sounds like a bodge. What are the chances of getting Crabtree MCB's from obsolete stock? I am in Herts.
