I need around 20m of 2.5mm^2 twin cable. There's the local swindlery and on ebay seems to cost 50 quid. Any alternative sources? Has to be proper tinned cable though!

thanks
 
Thanks, Riddal sounds good. Including shipping and VAT however you end up paying £ 43.20 for 2x 10m. Cheaper than ebay but I'll have to check with my local shop first.
 
cliff's link is about £24 for 50m and its tin plated wire suitable for marine use. Is there a reason why this would not be good enough (or about £20 inc. vat and del. for 20m of Tinned Copper Thin Wall Cable - 35/0.30, 2.5mm2, 29A, cable OD 3.0mm - 010902 Red? The reason I ask is I will buying reals of wire for a winter refit. Is this not "proper" tinned cable, which I assume is lower specification and less suitable in a marine environment?

Local scrap yard. Been the source of many a high quality bargain for me.

Only got a boat yard nearby. OTOH could be the same thing by the looks of it!
Chandler knocked the price down from 2.50 per metre to 2.15 per metre, undercutting Riddall by 1p :D
Well cash & carry vs shipping of course.
Blue mischief's supplier would've been cheaper per metre (1.60) but since 20m is already plenty I didn't want to buy 30m.

Thanks for the help!
 
The problem is I already have more than enough but never the right size or I can't find it. Space on a boat tends to be limited unfortunately.

I understand now, not so low cost after all for the single core stuff as suggested. Thanks.

But.... do you really need twin core? I run a power feed to individual lights and use a common return - the 2.5mm will cope with 29A and as one tends not to have all lights burning at the same time a common return is adequate. For other uses such as Radar then a dedicated return may be warranted. I have 10 lights in the forward section between the heads, forward cabin, coat lockers and mast but would not have more than 3 or maybe 4 of them on at any one time so one common return saving 9 redundant cables @ ~15m each - that is a lot of saving.

You should take care how any common return is laid out, as creating a current loop of any size may send your compass off...

It is prudent to check how many volts are left at the end of a run with a representative load. it can be interesting!
 
call a good cable / electrical distributor and ask for twin butyl flex or 'ship wiring' in the size you require, both of which should ordinarily come as tinned though just ask to confirm. might find them cheaper then the swindlery and most likely of better quality.
