When are fuses necessary?

[Justin Case]

Will JBL S312 speakers (250 watts) need to be fused when connected to a WOPL 400?


The PL owner manual goes through this.

Thanks!

That's borderline as the 400s will put out just over 250wpc/ I would fuse them for peace of mind

I got a source for mid-ranges, but your method is more cost effective!

Yours tested at 241, 242.....

You could omit fuses on the output of each string, all thanks to the rating of the OCPD of the modules. I chose to show this example because it illustrates that careful evaluation of the modules in the system can help to not only determine when to fuse but also that in certain situations where you may think it is necessary it turns out that it may not. Considering these variables helps you to ensure that your circuits are indeed protected and in turn could save you from having to add fuses to the circuit outputs when it is redundant or unnecessary.

NEW fuses are only necessary when you ran out of tin foil...........
