Will this fit a CED Garage consumer unit.

Asked by: Pedro1010
Hello. As per 18th Edition regulations you cannot mix manufacturers brands so a Wylex MCB should be fitted into a Wylex unit. As always you should consult a qualified electrician for any installation work. Thank you for your interest in our Wylex brand.

Is this a direct replacement for NSB20?

Asked by: WanWei
Hi, This product is part of the NHX range of MCBs and cannot be used as a direct replacement for the NSB MCBs. The 2 different ranges cannot be mixed in the same unit.
