In the following, some of the most important differences between the two standards will be indicated.įrom an application point of view, a fuse holder is characterized by the features discussed in the previous section by its rated values for voltage, current, and accepted power. In the case of fuse links, compliance with the UL-standard does not usually mean that the fuse holder under consideration meets IEC-requirements and vice versa. 2 to this publication dated January 1989.īoth standards show considerable differences. IEC-publication 257 (1968) and Amendment no.The most important standards for fuse holders, which specify requirements, characteristics and testing methods are:

How much is available to spend on safety and reliability?.

Should the fuse only be accessible from outside the appliance?.

Should the end customer of the appliance have access to change the fuse?.

How often will the fuse need to be replaced?.

Will the fuse need to accessible for replacement?.The first step is to answer the following questions: Lastly we have the Yellow Fuse and this one is in fact the 20 AMP, so set that accordingly.Selection of the Fuse and Holder Solution

Next we will play about with the Red Fuse, for this one you will want to insert the 30 AMP into it, do so. Okay well we will start with the White Fuse first and the correct AMP for this one is in fact the 15 AMP, (as seen in the above image) so slot that one home We also have several different AMP fuses to play with such as a 15 AMP Fuse, 20 AMP Fuse and a 30 AMP Fuse and all of these wonderful AMPS need to be placed in the correct places but what exactly is the correct place exactly? So here we are face to face with a Fuse Box that we need to solve, however how exactly can we solve this issue? We have some written messages on the door here but they are a bit vague, hmm.
