Electrical : Time & Current Characteristics for BS 1362. (3A, 5A, 13A)

In this video, a selection of BS 1362 plug fuses are subjected to excessive currents to get them to fail. This is the TASTY EDIT. The ratings which are going to be examined are the three most commonly used: 3A, 5A and of course, the 13A. The plan is, to subject one fuse of a particular rating to a gentle tease. This is done by gradually increasing the current flowing through the fuse.....Until it fails. On this test, the current is measured with a clamp meter and catalogued in this video. After that test, another fuse is also subjected to excessive currents, but this time, instead of the teasing method, this one has the excessive current slammed straight through it, full-on instantly. Before this test is started, the device which sets the current amount (a 10A variac) is very slightly reduced from the setting which caused the previous fuse to fail. For the "instant-on" test, a stopwatch is used to document the time characteristic. The two tests above are carried out on 3A fuses, then repeated on the 5A fuses and then the 13A fuses, all with documented current characteristics, as well as the time characteristic. For whatever reason it may be, BS 1362 isn't listed in the Wiring Regulations, 17th Edition, BS 7671, so this prompted me to make this video so that you can become knowledgeable about the sometimes surprising disconnection currents of plug fuses! Thanks for watching, peoples. -BoomBoxDeluxe.
