i hope to find the exact amp fuse i should use for the series of 4 cobs,,Fusing the dc side at 5 amps is not going to save the cob. The max amperage the 36v crees are rated for is 3 amps I believe. Make sure the fuses are rated for the voltage you intend to run them at.
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 buildsi 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
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.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.
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.
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

What is the max amperage rating on the cobs you are using? That is the fuse amperage I would use to protect the dc side. Anything with a higher amp rating will only save the house.

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,
No, I meant holder....not fuse...excuse my faux paux....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 amp
Why not both and what does grounding have to do with fusing.....Not a damn thing.Can't you just ground to the frame and call it a day?
