"I have bought these breakers before and I am about to install a garage unit in my new workshop, Wylex have an excellent name in the industry, Now retired from sparking I still use the wylex consumer units as they are simple to install with plenty of space for wiring and these breakers seem to go on for ever. providing all terminals are tightened. Very fast delivery from Screwfix, I could have shopped around a bit and got these slightly cheaper, but for me when time is important. I would rather pay the extra. I have used these also when teaching in College, and they stand up to a lot of abuse. Well recommended products and fast delivery"
