Good evening,
As the title suggests this could be and probably is a stupid question.
I've been flicking through posts and noticed a post regarding a fused switch isolator being installed before a run of SWA feeding a DB.
Why would a fused isolator be necessary if feeding the isolator is the main incoming fuse which itself obviously had a fuse in similar to the fused isolator? Why wouldnt it be possible to just fit a 2 pole 100A switch for example?
Don't see why this is any different to the main fuses feeding a board located directly adjacent to the incomer if the SWA is adequately sized.
