Hi All,

I thought I'd start a new thread as I could do with an answer asap (to
possibly get stuff moving) and I didn't want it to get lost on the end
of a similar thread ..

We had a letter the other day saying our meter was due for a change.

I also read a post here suggesting running some extra tails to feed a
garage supply?

So, some questions come out of this ..

1) We currently have a dual rate meter (E7 or similar) with a clock /
switch feeding a second CU running the storage rads. Will we get a new
dual rate meter controlled by radio and if so how will they deal with
the external switch for the E7?

2) While he is there doing the meter swap, would it be a 'good idea'
to fit some sort of isolator / RCD ready for the pending feed to the
garage. If I had the 'box' fitted nearby with a pair of suitable tails
'a dangling' would he / she be willing / able / allowed to hook it in
for me?

3) If they take away the 'switch' part of the E7 service (can they do
that?) I would be forced to add my own time-switches to each storage
rad. Would they supply them to me foc?

4) The CU for the storage rads is a nice MK Sentry 9 way (7 modules
and 1 x 2 wide incommer) steel unit with only 2 ways in use (was 3).
Maybe I could replace that with a smaller unit and fit the garage
'box' beside it. I could even possibly use the 9 way unit down the
garage as a split CU (Sw lights MCB, Lathe MCB, RCD, std ring Power
MCB etc?) Am I likely to get bus bars / modules to suit this if I cut
it down? Am I right that the SWA should to be 'protected' by an RCD
(and that's where I would use a 100mA unit with a 30mA at the garage
end? Is it likely I could fit the contents of a cheap plastic Clipsil
garage CU into the MK box?)

So I would end up with ..

Main split CU for the house (with existing 30ma RCD / MCB's)
Sub CU (no RCB etc for the storage rads / E7 cct)
Garage 'd/p Switch protection box' (with single 100 mA RCD as switch)


If anyone has any brands of module to hand I have a blank here for the
Sentry and it measures ..

The metal mounting rail is 35mm wide (*high* if you look at it from
the front)

44mm from the front face of the rail to the inside face of the cu
front cover (or module lip)

45mm high module (here it goes through the front panel)

18 mm wide module.

What to do ... ?

All the best .. you humble apprentice ..
