I ordered a 6 position fuse block with a cover to run lights/CB radio off of (see pic below).

The box has 6 positions and a "in" and "out" connection for each fuse. My question is, can I run one wire into the first position and then do a little jumper wire off of that into the next 5 (to avoid running 6 12v wires from the battery)

I currently have an extra fuse box, but wanted this one because it has the cover...

 

The wire I currently have is 6awg so it shouldnt be an issue...then I will use like 12 or 14 awg wire to connect the additional 5 posts to the one main...

I have a CB and 2 sets of lights (one up front, and one back) both sets are cheap $30 sets and there is no relay so they go direct to the box...

 

As long as the main wire can carry the combined load of all of the accesories you are fine.

What unit is that? Looks interesting

 

14 gauge will safely handle less than 10 Amps, lights chould go through a fuse or fuse block.

you can only use the fuse block at what it is rated for. If each fuse is rated for a max of 10 amps than don't try running more than one 100W lamp of each fuse, the terminals won't support it.

So just what is it rated for?

 

It is the 6 terminal fuse block on wiring products dot com. Just search "fuse
block" and it comes up. It comes with a cover, in the description it says dust cover, but it looks waterproof...it has a black gasket around it and closes very secure...

I just bent each tab and screwed in a metal plate on the side over all of them, then I hooked one 6awg wire to the plate. each terminal is rated for no more than 30 amps, but no more than 65 for the whole unit, so ill be fine, I only have a total of 50amps on it now.

 

Looks like their website is down but thanks for the info. Looks like a good solution.

 

Here is some info, look at the 12VDC chart.

windsun.com/Hardware/Wire_Table.htm

Your 6 AWG wire should handle 40 amps up to 13 feet away with 12V and 30 amps at 18 feet.

 

Trust your electrical guy, obviously the electronic guy is a dolt.

The ratings you posted were for stranded wire, solid wire would never support those amp ratings without long term problems.

Just a little sidebar for you, electricity runs on the surfaces not inside the strand which is why stranded (and the more the strands the merrier) carries more. Boulder dam uses copper pipe so that the flow is on both the inside and outside of the pipe.
