The travel adaptors, Richard stated that the fuse is there is protect you from an electric shock. Sorry, but the fuse is to protect the flex and sometimes the appliance. I could say, for example, cut the end off an IEC lead, exposing the live conductor and plug into a socket (I DO NOT RECOMMEND ANYONE DO THIS) and shock myself with 230v (BTW, I won't be doing so). The fuse in the plug, say 13a will not blow as the amount of power needed to blow the fuse would have to greater than 2990watts, as they tend to blow at a slighty higher current. The body would receive a shock but not blow the fuse.
Hi just wanted to add a quick comment with regards to the points raise about our video and the purpose of the plug top fuse. Firstly it is always hard to strike a balance between producing a short video that can be easily understood and including detailed technical content. In this case we were keen to highlight the fact that the counterfeit lead featured in the video had no fuse, which is a key safety concern and chose to highlight the shock risk as this is easily understood by most viewers without the need for a detailed technical explanation. To clarify with regards to the fuse, the plug top fuse actually performs several functions. In addition to providing overload and short circuit overcurrent protection, it also forms part of the fault protection for class 1 appliances ensuring automatic disconnection in the event of a fault between live parts and exposed conductive parts. The fault protection therefore protects the user against electric shock by indirect contact with exposed conductive parts made live by fault. Kevin Smith Seaward
Another quality training video from Richard.

The demonstrator must reply.

Excellent, thanks Kevin!
@@SeawardElectronic great course very factual
Thanks Patrick
