Busbar chamber

[sparky87]

Hi all, Have a 200amp bus bar chamber located in a maintenance shed that feeds several isolators/ DB. This is fed from a 100 amp 3phase switch fuse located at the origin located within a different building some 70-100 meters away at high-level. Does the bus bar chamber require local isolation? I.E switch isolator on incoming cable? many thanks in advance

Well I would have thought so

Whilst strictly speaking it may not actually require one I think it is very unusual not to have one installed.

Like above, ideally you would have an incomming isolator as a local means, having said that as this is an existing install, if the front end Sw/F can be locked off then there isn't any real need to address the issue, anyone working on the busbar can safely isolate and lock-off the front end which would be fine in my books for an existing set-up.
