Re: Re: DIN Rail connections



2 things...

You can buy "naked" DIN rail in metre strips very cheaply, I got
some strips
at Maplins a few weeks ago, for (IIRC) 49p per strip. You can see an
example
of this here, where I have cut a small pice to length  to screw to a
backboard which is hidden away in the loft...

secondly, this consumer unit...

is pretty cheap, - only £19 from Screwfix Direct, and will take up to about
a half dozen modules happily enough....

Food for thought....
