| Hi all, I'm about the start wiring. Have got a 6 gang rocker switch but am slightly confused about the cable I need to connect up the spotlight/cooker/bilge/kettle etc. Obviously it needs to be 12v, with just positive and negative, and able to manage the ampage for the individual devices, but does it need to be a certain thickness? Thanks Andy |

Kettle? Everything except a kettle (240v or 12v?) can be 0.75 as it's all low draw stuff but the kettle - 2.5mm if it's 240v, otherwise probably a battery-flattening 6 to 10mm dependant on current draw.
6-gang "rocker-switch"? I assume you mean one of those pretty black metal switch panels for boats with switches and fuses incorporated. You need to make sure the battery cable feeding it is man enough for the job. At a guess at least 6mm feeds via your battery master switch, all properly soldered or crimped ends.
And a cooker??? You've got an electric cooker? Now that has to be 240v or were you thinking of a spark supply to a gas cooker? Low draw if 12v, likewise if 240v. Do you want to confirm what you are using and what voltage?
Finally living the dream!

Twin electric hob is 240 volt? 2.5 twin and earth if so and follow Boat Safety Scheme rules.
On 12 volt probably a battery melting 10mm at least at a guess although I've never seen a 12v electric hob.

Don't even think of using twin & earth on a boat, it's solid conductor and prone to cracking with vibration, any wiring on a boat needs to be multi strand conductors whatever voltage.

Properly tubed and clipped it is fine, dangling from things is not and the BSS rightfully condemns it. New narrowboats are wired in it all the time, they don't go to sea and bounce about (generally) and I suspect the OP won't either.
Still trying to get my head around the 12v twin hob bit. Even if 240v relying on not tripping shore power out with both on at once is futile and I suspect it will prove to be a no-no.
U 571 or similar would be needed to cope with the required battery power.

I'd have said just a diesel engine sitting at the same rpm for hours on end would set up vibrations, I wouldn't use it.

Don't see many Listers or Kubotas in Norman 20's Dave,
