Fuseholder - wiring of.
I'm sure I read somewhere that there was a correct way to wire panel mounted fuseholders.
The ones I'm talking about stick out 90 deg from said panel or chassis and are barrel shaped with the fuse sitting in a cap, that then screws into said barrel. There are two terminals to affix wires, one on the side one on the bottom. I think the "IN", IE from the mains live, from an IEE socket goes on the side, the "out" to the switch goes on the bottom. Is this correct? Andy.

Re: Fuseholder - wiring of.
If you mean this kind of holder: http://www.newark.com/bussmann-by-ea...unt/dp/63K9385
The live "in" goes to the bottom. If you wire the "in" to the side, there's a chance that if your fingers happen to be overlapping the cap and touching the metal bit as you insert the fuse-and-cap into the barrel, the tip of the fuse could contact the 'side' contact in the barrel of the holder as you put it in and cause a shock. Wiring the 'live' to the bottom-part of the holder makes this impossible. There again, it assumes you've got the power supply incomer wired with correct polarity! |
