Dual Tariff or dual RCD

chris day · Jun 13, 2018

Hello everyone

I currently need to change a dual tariff (economy 7 & on peak) consumer unit situated inside a flat.
One half of the existing split fuse board serves the storage heaters with the second separate half being the On peak supply.

Am i correct in thinking a standard dual RCD board is effectively a dual tariff DB.
Just making sure i am not being a numpty in my thoughts? which is quite often the case.,

No it isn't, a dual tariff board should have two isolators one for each supply. A dual rcd board has one supply and one isolator with two rcds for the additional protection.

There we go i thought i might have missed something

Easiest solution if space allows is two separate boards and using rcbos will be more space effective.

High integrity board will do the job

This is how we do it place the offpeak tail in the last rcd then link the main neutral

The yellow, black, red and blue look like they are swa cable which is floating behind the board. How long before the black lashed into the main switch starts giving smoke signals. If one of our lads did that we would sack them.
