Fuse board cable sizes


Recommended Posts

Hi,

I’m about to replace the fuse box in my 1977 Triumph Spitfire and may need to extent some of the cables which go into the box,

Top fuse

1.      Green for: -     Wiper switch, Heater fan & Stop lamp switch

2.      White for: -    Ignition

Middle fuse

1.      Red/green for: -  headlamp switch

2.      Red for: - Instrument panel, Indicators, Brake, Map, Side light & No. plate

Bottom fuse

1.      Brown for: - Alternator

2.      Purple for: - Dip flasher switch, Horn relay, Boot light, Door light & Seat belt

Firstly is the above correct and secondly what size is this cable, is it all 35amp as it’s a lot larger than the rest of the loom?

Many thanks

BC,

Here is a link to a GT6 fuse box replacement that you may find interesting. The wiring is similar, green, white, red/green, brown and purple. The 3 fuses are 35a blow but are not excepted to run continuously at 35a. The wiring sizes are in the thread, somewhere! :)
