I have been asked a few questions that I myself am having difficulty finding concrete answers to. Does 4836 permit a non-electrical worker to access an LV panel and reset an MCB, replace a fuse, change parameters on a VFD/Servo or plug an ethernet cable into a device for programming purposes? For most of these jobs the LV side would be isolated via the main isolator with 24Vdc being supplied separately and still active, however some drives do require 3 phase to be up as they internally generate their own control power. If they are trained to do the task safely would they be considered a 'competent person'. The people accessing would be engineers, not just anybody.
I was also asked if a non-electrical worker could help with panel building (LV again) so long as no power is applied. I believe this one is prescribed electrical work and would be a no, but am thinking may as well ask here as well to be sure.
Thanks
