I need some 10A fuses to use in 120 or 240 VAC circuits, found them surprisingly high-priced on ebay.
But, I have a pile of automotive 10A fuses (for DC circuits), rated I believe at 32 VDC.
Looks like I should be able to use these DC fuses in AC circuits, no
1. the RMS AC amps rating should be equivalent to the constant DC amps rating (equivalent heating effects to burn the fuse on over-current)?
2. I still can't see how the fuse's voltage rating matters here? A fuse is for over-current protection. The voltage drop across the fuse is minuscule. Which voltage are we talking about?
Anyone can shed more light on this.
