Jumbo Fuse Connector Block Cable Connection (1 Viewer)

[clanjones]

Hi - Looking for some advise on how to make a proper connection for a battery cable.

I have a 50 amp fuse between the habitation battery positive and the fuse box. The cable that currently connects to the battery from the fuse is not really long enough in my view and hence I need to either make or buy a new cable.

I have bought a new fuse holder and it comes with these cable connectors. My question is how should the cable be connected? Crimping + solder? I consider this to be pretty important so if I have to go to an Auto electrician I will but thought I would ask on here first!

Crimp and solder....belt n braces every time.

How long is the existing wire ?
Needs to be as close as possible to the battery.

About 8/9 inches - it really needs to be a about 12 inches. I may well leave well alone until we come back off our next trip, we go in 6 days!

Crimp only, the same reason you never solder a cable that is going into a screw terminals. Solder and copper have different thermal expansion rates and under pressure the joint will work loose.

Agree with Lenny HB. Soldering also stiffens the cable just as it leaves the connector making it liable to fatigue failure. The correct crimper is here:

.............. either of the first two on the page.

Other suppliers are available .

Is that why every electrical item bought minus plug (12v or 230v) has tinned copper wire ends ready for a plug ?

Blimey how long since you bought a 230v item, they have not been allowed to sell them in the EU without a plug fitted for about 15 years. If you open the plug you will find they usually have brass ferals crimped to the end of the wire.
Leads on other items that are tinned is for convenience when manufacturing and packing you should always cut them off before connecting.

I bought these Crimpers when I fitted my solar panels and find them very good.
