I kind of agree with BAS on this - the reference to maintenance-free terminals in Appendix 15 seems to be a bit vague. The Appendix itself deliberately distances itself from Part 5 at the top of the page and then makes reference to it (526.3) at the bottom of the page. What's that all about?
Wago boxes do carry the necessary BS EN 60670-22, but I am still undecided whether it can be used in an inaccessible area. Well, going by the regs I am.
