Dual tariff consumer units?

[lilman]

I need a new consumer unit that can house both peak and off peak supplies in one unit. I know they exist somewhere - anyone know a good supplier/brand. Basically I would like one that has main switch/dual RCD protection on one side, and main switch/RCBO (night storage heaters) on other side.

Thanks all

why dont you fit 2 boards ?

 

[lilman]

Trying to free up some space - will probably end up with 2 boards though.

MK do a multi incomer kit for the sentry range of consumer units.

If you've got the width a 21 module units will give loads of flexibility or you could use a stacking kit to stack two smaller units vertically if you don't have the width.

It might help us to help you if we knew how many outgoing ways you need in total and the split ratio. Also, what is the maximum width available to you in the fitting space?

There are currently 6 circuits on standard board (cooker, lighting, 2 ring finals, 1 immersion and radial/boiler), and 4 on off peak (3 storage heater and immersion). Property is a flat.

Width not too much of an issue, height is though. Currently the off-peak board is below the other board, but needs to be moved up.

Are you saying there are two immersion heaters? Are they side entry types, one at bottom one near top or a dual element top entry type? Presumably one is on E7 and other for boost.

 

[lilman]

Yes - one is a daytime boost

"radial/boiler" - is this a dedicated circuit for central heating only? or does it supply something else as well? What size cable?

And does the central heating also do hot water?

MEM do a dedicated dual tariff board. Fitted a few and worked well, I used rcbo's instead of two rcd's though

Used a MK split load arrangement with 3 neutral bars.

1 side for main switch RCD (off peak) + 4 mcb's

2nd side for RCD + half off peak ccts

3rd side for RCD + other half of circuits , incl 2 convectors for storage heaters
