Elec cable colours for re-wiring ?

Have a look at the ISO standards for boat wiring, and some areas of BS7671 that apply to such circuits. BS7681 is expensive, and not a lot of help for boats, but the ISO standards are available free with a bit of web searching. Re colours, not too important but they advise against using AC mains colours for DC circuits, and segregation of ac and dc wiring. See:
ISO 10133 Small Craft Electrical Systems, Extra Low Voltage DC
and
ISO 13297 Small Craft Electrical Systems AC

If you really want to comply to the standards then please don't use the online available versions, they are out of date, they were updated recently, also there is a way of interpreting the standards, they do not advise against using certain colours if AC colours are aboard they forbid it. Not that any of it means much to DIY cabling as there is actually no compulsion for you to comply.
 
Thanks David, I didn't know they have been updated, better update mine. Have they changed much? Sorry, yes, advise should be forbid. ISO's can be expensive; just been looking at some of those required for coded boats, near £200 each! Guess there must be specialist libraries around that have reference copies, hopefully up to date.
 
Latest copies with current dates are on the BSI website, actually they are not that expensive if you are a member, and of course have enough use to get the value from them.
 
For a multitude of cable colours, a lot of automotive suppliers do tinned cable, by the metre. So if you want pink with a red trace.... You got.....
Somewhere like vehicle wiring products, in ilkeston.... There are others, but that one springs to mind...

BS7671 is for electrical installations in buildings and is published by the IET the aspects of BS7671 which you maybe alluding to is for electrical installations in marinas.

The IET also publish a book for the standards required for ships etc but will not be would not for recreational craft.
 
Will Grundy at Ullswater Marine has held my hand in metamorphasis from hot ex dinghy crew
to experienced engine fundie.

In my rush to "sort" my new love, not only did I drill through the diesel engine supply pipe but
I severed the engine wiring loom. 17 connections: you soon get to know wiring colours!

I referred to Volvo's engine schematic and I have had no problems since.

Ok, except for running aground on the neighbouring yard's sand bank.
 
I use short lengths of heat shrink round each end of the cable using the standard resistor colour coding (black = 0, brown = 1 etc). Heat shrink is cheap as chips and different sizes cope with different cable diameters.
