I have a 3 phase fused Distribution Box in my Garage , I want to run a 63A RCD Garage unit CU from it ,the fuses that are in are 20A double fuse holders , the feed to these is a 10mm2 4 core swa ,the earth is via the armour . The problem is that there is not enough room in the bottom feed in to the 20A fuse holder to take the 10mm2 that is in , and another 10mm2 I need to take the feed from . Anyone have a idea how it can be done , I was thinking of using a Henley block in some way , I could of course change the whole DB box , but at this moment I need a easier way if not temp way at the moment ,
If the garage electrical installation is part or connected a domestic dwelling it come under part p, as all domestic electrical work does! If the garage is not part/connected to a domestic dwelling I assume it can only be a commercial/industrial project.
With respect to the electrician that you are employing to undertake the work, they really are the best person to ask/answer you questions, as they will see the installation in full.
