Re: Re: DIN Enclosure for CBus modules

[Phil Dye <phil@xxxxxxx>]

I was discussing this with a friend on Saturday night, who's a
building control officer for a local council; their take on this
(since each authority is free to interpret "ambiguities" within
the
rules as they wish!) is;

- work carried out by contractors registered with approved
organisations (eg NICEIC) will be deemed to be OK, and will not
require building control inspection/testing/approval (note: inspection
!= a building control application, which is always required)
- work carried out by other (non-registered) contractors will require
inspection/testing/approval; either by another contractor (registered
with an approved organisation), or building control inspectors
- for DIY work, ditto
- he (and other inspectors) have just done a 2-day course on basic
inspection and testing, so they can approve. Anything complicated
though, and they'll need to bring in a contractor (registered with an
approved organisation) to do it
- building control application fees are fixed, so any external
inspection/testing won't cost the applicant any more
- the twist; the NICEIC have instructed their members not to carry out
inspection/testing for anyone else, not even building control. That
leaves a shortage of contractors (registered with an approved
organisation) who can do the approvals...
