    Why are main bonding conductors so big?

    Fair point, I may have wrote before reading the whole post. So I do apologise. Although fault current will flow in the bonding conductor in fault conditions, all be it the amount, which will vary on many circumstances. The primary selection will be to do with impedance as I said. I'll leave...

    Probably what she was doing. Shuffling along the carpet and charging... Lol. Then discharging to earth lol

    If it is static, fit a switch with screw covers. Problem solved lol. Saves her panicking

    Switch arching?? Wet hands?? Deteriorated switch? Something could have damaged insulation and plastic. Oil or something? Have you tried it? Lol

    Why are main bonding conductors so big?

    Bonding will still take fault current in a fault!! And yes negligible impedance is 0.05.

    Why are main bonding conductors so big?

    Fault current what flows in the bonding conductors in a fault condition. Just think of the PeFC you measure then you will realise why.... ohms law shows higher resistance means less current flows, this is why TT can usually have smaller conductors. Another reason for this is to keep below the...
