Yeah I know about eddy currents, which will NOT be present in the arrangement in your picture.

I agree - looks like a bit of the old scaremongering tactics to get work

Just goes to show - the NIC are not the be-all/end-all.

Electromagnetic effects from incorrectly installed cables of alternating current (a.c.) circuits can cause heat to be generated in the metal of ferromagnetic enclosures, such as steel conduit or steel equipment housings. To prevent such heat, which may damage cables and other materials, Regulation 521-02-01 of BS 7671 calls for the following requirements to be met:
(i) Single-core cables armoured with steel wire or tape must not be used for a.c. circuits.
(ii) Conductors of a.c. circuits installed in ferromagnetic enclosures (such as steel conduit, trunking or ducting) must be arranged so that the conductors of all phases and the neutral conductor (if any) and the appropriate protective conductor of each circuit are contained in the same enclosure.
(iii) Where such conductors enter a ferromagnetic enclosure, they must be arranged so that they are not individually surrounded with ferromagnetic material, or other provision must be made to prevent eddy (induced) currents. [/b]

since those MICC cables are multicore cables they meet both of the criteria i've highlighted and therefore conform to the regulation..
that regulation is to prevent SINGLE core ac cables from entering metal enclosures through seperate holes..

your website is therefore willfully misrepresenting the facts to convince the potential customer that a change is needed..

Why are you using a full scope NICEIC logo on your website, when infact you only have DI status?

Your not up-to-date: try Megaman Dimmable Series - new forms being added weekly.

Those lamps are still not dimmable in the way that incandescent lamps are - you have to turn your dimmer off, then on within three seconds then repeat to get it to your desired level. You can't just turn the knob to whatever brightness you want.

they are selling old black / red cable on e-bay with the tag line "DIYers - repair your wiring with the old colours before its too late"...

it's already too late since the new colour code came in a while back and the changeover period where either colour coulkd be used expired a long time ago..

You are referring to Dors not Dimmable !!
In January this year Megaman released these new lamps - I quote:

MEGAMAN® has invented the world’s first linear dimming CFL that is operable on conventional dimmer switches, and allows you to choose between full lighting or more dimmed atmospheric lighting. The DIMMERABLE® lamps works perfectly on any incandescent dimmer or standard switches with absolutely no additional control wiring and transformers needed.

Thanks for your observation - I have removed offending paragraph - I will review the section in BS7671 to confirm my agreement!

I took a look at the web site and found it a little bizarre to say the least.
Quite confusing regarding the other aspects of what "Aquae Viteae" actually do!
I did note the point about what the name stands for... "waters of life"
we all know that water and electricity don't mix. perhaps there is a lesson to learn here!!!

Also I notice that it offers an inspection and testing service but only feels the need to quote C&G 2381 !!! I would have thought 2391 would be more relevant.

hmmm!!!
