Guys, my electrician says that the new model domestic Wylex RCBOs are a direct replacement for the older NSB model RCBOs. But Wylex have said that the old type NSB cannot be mixed with the current model, but the old type can be fitted to a current NH consumer unit.
I've asked my electrician and he's not giving a direct opinion.
I've got a handful of the older model NSB RCBOs, but not enough. Either replace them all or can try to buy more older model ones from fleabay? Or just mix them?
