Completing electrical certificates Discussion ThreadCompleting electrical certificates Electrical Advice
Hi all, question on testing and completing certificates inside a large factory in maintenance, a lot of the 3P boards here are full of cables, when we are adding to existing circuits, it would be required to perform the necessary tests, R1 R2 and Zs for instance inside the boards, how do we go about this when we are unable to isolate the board, having to open up an old board rammed with cables opens up risks itself. Is there anyway around this or must we be disconnecting from the earth bar every time we work on the circuit. Thanks
