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.
