The IET is carrying out some important updates between 17-30 April and all of our websites will be view only. For more information, read this Announcement
Sparkingchip:
Highest voltage and current it has to withstand after a failure of the FELV transformer has put the primary circuit voltage onto the secondary circuit along the the primary circuit fault current.
The secondary circuit could have 240 volts and several hundred amps to deal with if the transformer insulation breaks down livening up all the earthed metalwork.
