[QUOTE="SPECIAL LOCATION, post: 382425, member: 250"] 6way consumer unit for a shed??? How big is this shed... Sounds like one big overkill to me? A 100A RCD or a 63A RCD is not an overcurrent device... An RCD is an earth leakage residual current detection device.. Yon need to look at the tripping current e.g. 100ma or 30ma and if it is time delayed or not.. The large 100A / 63A part of the specification is how much load the device can disconnect / reconnect without the switch contact arcing, sparking or welding together! As Manator says.. You really need to get two other electricians to come and see the job and give you a price.. at the moment TBH it sounds as though two people are designing something in a very haphazard manner. e.g " clipping SWA along the top of fence" ?? Why not ring the previous sparky who left the 40A mcb in the house CU... (unless of course they are the "invisible" electricians who so often appear on internet forums) Or is this all just a DIY project? :popcorn [B] [/B] [B] [/B] [/QUOTE]
