Valin -

I forgot to mention that Bussmann has circuit breakers that can be installed in lieu of automotive fuses in this buss. We have not installed cb's in the busses. We really like this buss system.

Valin -

We used all fuses in two electrical busses (dual battery, dual alternator wi/ crossfeed). Both are mounted on the panel but could be located elsewhere. On our ES panel there was room. The busses boxes are dual - you can feed 20 on the top and another 8 on the bottom from a different electrical feed. They are made by Bussmann Model 15712-20-08. We only have two breakers and they are for the alternator fields. We have never gotten a nusance trip, but that is why we put them in. Check these pictures:

The fuse panels are on the right side. We pretty much used Bob Nuckolls' dual battery/dual alternator design with ground power added, and jacks for a trickle charger to each battery.

Hope this helps.
