I need to run some instrument and internal lighting cables through a wooden box (almost like a conduit). Do I need to line it with sheet metal/fire resistant plastic conduit? Every step forward seems to come with two more jobs.
Ah well, it's the life we choose.
 
In general no but it's a good idea to clip it or fix it in some way to prevent chafing. Make sure it's fused with the lowest possible breaker or fuse rating possible.

In fact I think you will find the requirements to support the cables is spelled out in ISO 10133. Conduits and cable trays are mentioned.
 
Does ISO10133 apply retrospectively to last century's boats?

I expect so The Ark as well probably.

Would you not expect new wiring to comply with the latest standards regardless of the age of the vessel?

No, but I'd expect it to be done sensibly. If ISO standards were meant to be adhered to by DIY sailors, then the references would be freely available, not expensively paid for.

Never mind DIYers, the Swedish yard that built our boat certainly didn’t go in for cable trays and conduit. Most of the original wiring was tacked in place with occasional blobs of sticky black putty.

Thanks fellas - adding a battery box fuse to the system as well as a couple to the two feeds to the fuse box and breaker panel. Not much ISO compliance about to be honest, probably overkill as I don't want to go through this process again anytime soon.
