Battery kill switch

[sleepyfolk]

Good kit here generally and helpful if you need advice https://www.12voltplanet.co.uk/battery-cable.html
You can get the correct terminal ends etc from them

Great I was getting confused with all the earth cables available.

Does it matter if I use a longer cables so adding a max of 1.5m?

[lezmtaylor]

I don't think so, you are not likely to get a " voltage drop", mine are about 3 feet long .

You will always get a voltage drop over a length of cable, best to run the 230 v to the charger as near as possible to the charger, as a 5 volt drop is the max allowed, a 5 volt drop at 14 volts is not an option.
Is the car parked on your property/ drive ?
If so run a length of wired armoured 3 core 2.5 mm2 cable to an external waterproof plug adjacent to your car.
If not possible, you could have problems

I think he was talking about the negative lead interruption switch cable...

[lezmtaylor]

Well I was talking about -ve cable to kill switch.

Correct going with negative kill switch option. Wasn't sure it would work as most solutions talk about kill on the positive but Lez has shown me it can work and a far easier option to install.

About to order some cables, its asking whether I want m8 or m10, I am replacing the current cable so want to use the same point in the car, do I need m8 or m10 size?

Cables:
1 battery clamp to ring terminal
1 ring terminal to ring terminal

Cable Specification:
VDE 0298-4, BS638 PART 4, VDE0282-6, CENELEC HD22.6
Max Wattage (12V) : 2520W
Current Rating (A) : 285A
Rated Voltage : 100VDC/750V ac
Cable Diameter : 13.6
Ring Type: M8 or M10
Length : 48" 1200mm

[lezmtaylor]

I'll pass on cable and ring sizes as I have a hydraulic ring crimping kit and used what was appropriate (was a few years ago that I did the job), and as said previously a good quality spare -ve jump cable
The reason I used the -ve cable from battery is :all the Bentley workshop guides talk about disconnecting the Negative battery lead when doing electric work and a battery disconnect.

Switch has 10mm so will go M10
