Fuse or Breaker recommendations

wayneworkman2012 · February 2018

Hello,

I have six 100AH 12v batteries wired in parallel with 00AWG wire. I have one line coming off of one pole to a 250A DC breaker (ordered from here, love it) that then leads to a 3000 watt continuous pure sine wave inverter

What has been recommended to me here before is to rewire this, having all the positive poles go to a common positive, and having a fuse on each battery between it's pole and the common positive. I'd like to reuse my existing cabling.

Can someone recommend a fuse that accepts large lugs? Or should I just get several small DC breakers? Perhaps several 50A or 75A breakers?

I'd prefer to get NAWS breakers if possible because the one I have got in the past was great and accepted the large lug size without issue.

Blue Seas Dual (or single) Terminal fuse block

Bolts to the terminal, and accepts the lug that was going to the original terminal

Be sure to order the fuses, and a couple spares

I ended up getting three Blue Seas products to get this done.

@mike95490 Thank you for pointing me to this stuff. My largest problem is how much I don't know about available electrical hardware, I didn't even know what a terminal fuse block was until you brought it up. Again, thank you.
