Wire looks fine, the connection in thw holder must be bad.I'm going to skip the fuse holder and go straight to the breaker for piece of mind until I get better fuse holders.
This was the wire I replaced.
Yes, no difference before and after replacing the wire as well.Copper conductors both heat and electricity, so a bad connection or bad fuse holder will cause the wire to get hot.
Did you try loosening and retorquing the clamp screw? If so, I'd pop open the fuse holder to see what's inside.
I see you posted the answer to my current question just as I was asking it.Yes, no difference before and after replacing the wire as well.
I was having issues blowing 20A fuses a few days / weeks back but figured that was because I was running ~22A through them. I used a 25A I ordered the other day and figured I'd check temps after the recent fire thread...
Everything with the holder appeared fine.
I'll get some Midnite holders on order and see if they make a difference.
That's a good question.Why are the spec on the front (32a @ 690vac) vs the side (30a @ 750vac)?
According to the Amazon listing, yes.Is that fuse holder rated for DC? It probably doesn't matter it's just a fuse holder, the fuse is the important part.
Can't get much without breaking it open.Pics of the inside?
I see you found it.What current was the constant current running through it and the fuse rating?
I see you posted the answer to my current question just as I was asking it.
22 amps continuous throughout a 25 amp fuse, is likely the problem. A fuse is a resistor and creates heat to melt and blow.
Normal recommendation is to run a fuse at a max of 80% continuous. Stepping up the fuse to 30 amp would be the minimum to meet that spec.
Was the other holder doing the same current?
I'm confident they are tight enough.I had a similar issue at the breaker.
Was getting hot enough to trip it .
I THOUGHT I was able to 'torque' the screw down with just a screwdriver in my hand but went ahead and put a bit holder and bit on my torque wrench.
More than half a turn later, the issue iwas fixed.
Were you able to resolve this? I just got a thermal cam and so far only seeing hot temps in the combo box. Mostly around the diodes in the middle, 156f. (99f ambient) This doesn't feel good.I'll order some 30A fuses to go with the midnite holders.
Just curious, have you tried running it without the ferrules?I'll order some 30A fuses to go with the midnite holders.
I never did install the midnite holder and 30A fuses, temps were fine using the breaker.Were you able to resolve this? I just got a thermal cam and so far only seeing hot temps in the combo box. Mostly around the diodes in the middle, 156f. (99f ambient) This doesn't feel good.
I saw where @TomC420 said he replaced his diodes with a bus bar. Is this my best move?
I can't remember, don't think so.Just curious, have you tried running it without the ferrules?
Fixed the nuisance CB trips due to heat in the box.Were you able to resolve this? I just got a thermal cam and so far only seeing hot temps in the combo box. Mostly around the diodes in the middle, 156f. (99f ambient) This doesn't feel good.
