Can anyone send me a picture of their bus bar/advise me on the best option.



The ones that come with the Europa wiring kit seem to be plastic domestic

terminal blocks with one side (as it were) liked by wires/ring terminals

(Crimped not soldered ).



the wiring seems to me to add another point of failure whereas a straight

copper bar would eliminate this - indeed one of the crimped connections was

not crimped and I had to redo it.



Thanks

William, Mine  are brass bars pre-drilled to take bolts for ring terminals. 

The positive one has a plastic cover over it. The system has worked well. 

Unfortunately I can't remember where they came from! regards, David

Will,
	


I send to you a PDF drawing of my bus bar off this forum

Good evening

I bought some brass bar from the local DIY Store B&Q, in UK, drilled and tapped them myself.

Hi Will



Some bus info:

Worth looking here too at  flat thin copper wire, connectors and port negative inter ground wire connector/bus:

I just put a few bolts through the firewall. One bolt is connected to

ground, another to the 12 Volt power. On these bolts I can hook as many

ring terminals as I want, on the engine side as well as on the cabin

side. The amount of connections is only limited by the length of the

bolts.   And the maximum current is determined by the diameter of the

bolt. An AN3 will transfer more than enough current.

It is simple, economic, fail proof, light weight, it solves the problem

to get the power through the firewall, etc.

A bolt is just as good as a bar. And to fix the bar you need two bolts

anyway.

Will,



As with so many things in life nowadays, there are many alternatives.



I chose the Bussmann fuse block as depicted in the following link.  This 

unit

has its own bus bar (dual bus if required) that feeds up to 32 fuses.  Mine

is the 20 fuse model.  Only one wire needs to come through the firewall or

two if separate feeds are required for the dual bus.

I fitted mine as per the attached.



Cheers

Kingsley

I did the same as Frans, used brass bolts through the firewall as the main star points, I fed 5 wires with ring ends through a hole from the instrument panel and connected on the bolts so I can easily remove the instrument panel. I had noisy and quiet power and return and alternator output. Really you want the battery to be the bus (but then my battery is in the FWFD). In the instrument panel again I wired to brass bolts  on the ledge 2" from the bottom for ground star connections to low power instruments etc.

I am considering Vertical Power to simplify fusing and wiring.  Has anyone used this system?  http://www.verticalpower.com/
