what’s the best way to upgrade a economy 7 board, currently the is a board for the economy 7 and and another one for everything else, both boards need upgrading.
Well if you want to modernise the two consumer units you can install two new metalclad 18th edition consumer units, one for the on peak and one for the off peak. Have R.C.D. or R.C.B.O. protection that will protect cables buried in plaster less than 50mm deep and afford 18th edition compliance. A cheapo split load consumer unit can be used for the on peak consumer unit for economy, or an all R.C.B.O. board for the best most reliable protection and less nuisance if a circuit or appliance becomes faulty, as then each final circuit is independent of the others. The off peak consumer unit can have one R.C.D. and several M.C.B.s, but as off peak heaters can be come electrically leaky and trip off an R.C.D., the best option is a main switch and several R.C.B.O.s in the off peak consumer unit. Ensure the correct size of meter tails, and also ensure that the main bonding is up to spec.
All circuits and R.C.D.s/R.C.B.O.s should be tested after installation as well as Ze.
