We worked on it live. It’s 550V just to add to the fun.
How come there’s no live working on link boxes now? OK their a bit dodgy but if you were quick fitting or removing links the fireworks weren’t to bad. With a four-way box there must be one hell of a lot of disruption.
It's just the open busbar "calendar" boxes that we have in Birmingham that are made dead, all other link boxes are linked in live. The "calendar" boxes have concentric busbars that are only a couple of cms apart, the insulators are usually in a bad way and the links are big enough to go across the phases.
Normal link boxes with the standard links are fine for normal operation, I'll see if I can dig up a pic of our "calendar" box!
