    AC vs DC, live vs neutral

    Hi. I've read much about ac vs dc but can't find a 'simple' answer. If current alternates 50 times per second in a uk mains circuit, why do live and neutral not swap 50 time per second? On these forums, I've read that it does, so that copper does not migrate as it would in a dc circuit. I've...

    Fluke 1662 live testing

    Morning everyone I’ve recently bought a fluke 1662 as my megger 1741 broke on a site last week. Does the fluke have the same capability as the megger or do you just have to take the lead resistance off after the test ?

    Can Live wire runs through the Neutral side of RCBO?

    So I had an inquiry to make an electric panel (single phase) with RCBO, but it seems like our customer uses type C and F power plug (I live in Indonesia). This plug doesn't have a guide to ensure the Neutral would always be in Neutral side & Live to always be in Live side. Can I still use RCBO...

    Why did test lamps show 0V between live side and dead side?

    I removed a fuse and before reinserting did the following tests using test lamps. Live side - Neutral = 230V, Dead side - Neutral = 0V, Live side - Dead side = 0V. I then used a multimeter to check these results as I was expecting a potential difference of 230V between Supply side and dead side...
