EN61243-3:2010 and onwards two-pole voltage indicators cannot use fuses for protection as it introduces a risk of false clear indication; proving should alleviate this but the standard went that way anyway.

Great point, I shall add this to the video, as we can also get an external supply from PV sources coming in from elsewhere etc. Thank you for your comment.

why do we test at the bottom of the switch as i’ve seen the same video someone else does it at the top

Hi Clayton, thanks for your question. It all depends on where you are isolating. In this video the incoming supply to the whole board is isolated. Some videos just isolate the main switch to the board so will test the top of the main switch. Hope that helps.
