distribution blocks

hmmmm

ok..the blue sea safety hub look too good to be true... it is a fused distribution block for all my appliances a ground bus to reference all my stuff to ground and it says it has a negative bus ut inthe schematic it shows only the positive battery conductor going to safety hub..
hmmmm wonderiing now where the negative battery conductor goes...hmmm could it be that convienent that the safety hub provides a negative bus for all my negative conductors inclusing the big one from battery???
HMMMMMM lol

Like I said some distribution blocks have return buses, and some do not.

what about this 1

this is the one im looking at.. have you any experience with these blue sea
seems like solid stuff. i have 2 mbrf and two of thier switches.at the
did you notice the schematic has a terminal for a battvry charger... you mentioned it wasnt advisable.. is this a deal changer?? or stil not a good idea to place a AC battvry charger inline with power distribution??
learning is fun!

Jeff you can put the AC charger on the block, there are no code or technical issues to worry about. Well you gotta make sure the charger current does not exceed what the fuse or block can handle.

I have not used that specific product, but use a few of their products similar to that in my company trucks. They make good stuff.

....
I have the blue sea single terminal mrbf on both the neg and positive battery terminals. .....

That's redundant redundant.

????

I thought for a floating system an mrbf on each terminal wast he way to go??
i have no negative ground
elighten me oh sensei lol

Correct Sir if you are going to float the system you need to protect both polarities. Keep in mind that gets expensive on distribution because you will need two two distribution blocks; one for the positive and one for the negative wires.

Warning here a lot of the DC powered equipment you buy will have the negative polarity bonded to the chassis. That defeats a floating system.

I don't know that 2 fuses would hurt anything, just another part that could go bad. I also did not realize your system is floating/ungrounded.
I withdraw !

Well Mike actually fusing both circuit conductors can hurt something if the system is grounded. If the fuse opens on the grounded circuit conductor, then there is a very high chance the return current will flow on something not intended for to on like the equipment ground conductors.
