i hope to find the exact amp fuse i should use for the series of 4 cobs,,
its not about saving the cob, its about not burning down the house,,
all i could find tonight for testing was 10 amp fuses ,, so i put them in for first Light,,
any suggestion for a fuse rating for the cob Dc side,, and thank you for your help

Tim maybe starting a new thread for DIY safety sake ? I'm sure many would like to incorporate some type of fuse block in there builds
My concern is with the usage of blade style fuses in high voltage applications. The fuse holders you showed are generally rated for 12 volt systems and have a voltage max of 32 volts. The ac side is either 110 volts or higher and the cobs in series is even higher voltage.

I agree with the ratings being nearly unusable for the AC side, but I have simple blade style holders that easily do 300v 30A, so no worries if your blade fuse is sized correctly....as SDS told me long ago, a fuse is a fuse is a fuse.
You might just look for resetable fuses on the Ac side @Tim Fox......and you can also do MOV's for any of these applications, rather than a seperate fuse circuit....but understand that they are single use in most cases...!!!!!
So yeah, I would maybe look for the 300v 30A blade style for your DC side too or just direct connect 16 gauge single strand copper wire to each terminal, should be about the same ratings as well
Did you mean 3 amp on the dc side? 30 amp is a heavy fuse to blow when output of the driver is only around 1 ampI agree with the ratings being nearly unusable for the AC side, but I have simple blade style holders that easily do 300v 30A, so no worries if your blade fuse is sized correctly....as SDS told me long ago, a fuse is a fuse is a fuse.

Thanks for all the input,,, everyones words caused me to do some google searching about fuses, and it does appear that I should get a fuse rated for a higher voltage for the AC side,
@Abiqua assisted me years ago with a Cob build and the blade fuses have been on my dc side of the cobs for several grows with no issues,, i guess i just assumed i could put the same fuse on the AC side as well,
home depot has some round fuses and holders that may work,,
as well as the amazon fuses listed here,,,

I add an On/Off Fused Switch and Fuse to the junction box. This works well for the AC side.

If you like this, I'll add pics of the wiring and mounting,

No, I meant holder....not fuse...excuse my faux paux....

Why not both and what does grounding have to do with fusing.....Not a damn thing.
Fusing is also good for surge protection as well, not a lot, but it can help....just another type of safety.....GFCI AFCI's are great too and still get put in all my builds!

Alright, i got a 110 volt fuse for the ac side of things, and I am testing the light today,, I had to wait for thanksgiving 1 and 2 to be over with and everyone went home so i can proceed,, the cxa's are taking care of the plants in the mean time,,
so the first pic is the light on jack stands,, going to let it run for a few hours,, make sure no wires melt or smoke comes out of it, or fuses pop, and if everything works out,,
right now the plants are getting 200 watts of cxa's, and this new light will be about 250 watts of citi cobs
after the test the new light is going over these plants in my grow cab
