Re: Updated pics of my loft conversion

Dean,

Have you tried Futronix commercial dimmers?
Circuits are individually fused on the board.

We've been working with an alternative lighting control system following
years of Cbus - mainly due to customers not liking the Cbus contemporary
design.

Their system comes protected with 'B's - one of my guys managed to create a
dead short which the 'B' was to slow to re-act and it blew the Triac.

The good thing with this system is that the triacs are all engineer
replacable and my guy's now carry a few spares in case of emergency :)

Having protected all our CBus installs with 'B's for years - I now wonder
if
we have just been lucky that we havent lost any triacs in them....

Dean.

I might have been mistaken then - I remember fitting a different type of
MCB
in my workshop to protect woodworking equipment. Maybe it was type D?
