snip info from Andy and Christian on grid switches

Thanks Andy and Christian,

The grid system looks very useful for my needs, but I have difficulty
visualising the terminals on the DP and fuse modules. I have
downloaded the MK grid pdf file from TLC (I found them once I know
what to look for) but despite all the useful info and pictures not one
view from the rear of the modules.

I currently have the ring main going into the unswitched side of a
single FCU
and then continuing into another FCU (unwsitched side) and then a
double socket and then a third FCU (unswitched side) before returning
to the ring. So the single metal boxes containing the FCU each have
3*2.5mm2 cables (ring *2 and cable to hidden unswitched socket), these
are a little cramped. These
faceplates are all mounted together touching each other in a
horizontal line.

Am I correct in assuming that the 20A DP switch has two input
terminals and two output terminals? Earth wires all connected to the
grid frame?

And that the 13A fuse module has two screw terminals?

I assume that I would make the ring main up by using links between
modules?

sorry about the extra questions.

thanks

Ian
