Off peak and peak consuker unots combined?

[dokkan1080]

Is a board layed out like this correct for an eco 7 off peak supply and a peak supply?

Two isolators that feed seperate rcds.

They have a shared neutral which is split at a Hanley block.

The peak live, neutral and earth enter the cu via one gland,

And off peak live and neutral enter via another with no earth eddy currents?

They have split neutral bars but share the same earth bar...

See badly drawn picture.

For those with bad necks

A single isolator in the board to isolate both supplies

Common MET and separate neutral bars

That's the way I always did them anyway

Wouldn't you need a 3 or 4 pole isolator for that?
Or do you mean for an installation where the switching/timing is done by the loads, not by the meter?

Ya in the UK you probably would if you're breaking all the live conductors

Fusebox do a dual tariff CU that can be configured as per your sketch.

nobody's said "No" yet ?

For the off-peak feed in, as long as L + N go through the same hole, the fact that E doesn't is not a problem, given there shouldn't be much current flowing in it!

I see , 2 DP isolators

That wouldn't be allowed here for 2 supplies into a distrution board .

It's allowed in the UK as long it's clearly labelled that there are 2 separate supplies and that both need to be switched off.

I suppose ya

Wouldn't a 4-pole be simpler with no labels needed

Some of the newer peak/off peak installations have a 4 pole isolator fitted just after the meter. Which is a good idea.

I would agree that you really want a single point of isolation for everything, so if it were me I would look at using a 4P switch (even if one pole is unused, depending on just where it is located.
