"Dual RCD gives me much needed protection as previous distribution board was breaker only. The electrician was able to split out doubled up circuits and still leave me three spare for expansion. Worth going for that bigger box and good value from Screwfix."
"Don't buy a Crabtree Starbreaker consumer unit! Screwfix only stock limited MCBs and not the 100A main isolator (100/2MT) which is very hard to source, should the original go faulty. This has happened to me and I have had to buy a complete consumer unit (£125) for a £12 switch!"
