Fats Flyer Posted May 15, 2008 Author Share Posted May 15, 2008 Hi Eric, yes you are nit-pickingyou bad man,....right.............lets start again for the sane..........i would like to know what the safe amp ratings are in the different size of multi stranded copper wire in a silicone covered sheath(is that better eric).The reason i would like to know is mainly for multi motored(not engines eh timbo) systems so im not adding more weight than i have to....phew..........

Brian Parker Posted May 15, 2008 Share Posted May 15, 2008 As a rough guide... A single strand of 0.1mm copper wire will carry 0.05A.......i.e. 500strands will carry 25A.A single strand of 0.2mm will carry 0.1A..........i.e. 250 strands will carry 25A A single strand of 1.0mm will carry 3A.Length is not an issue in this context as a single 0.2mm dia. copper wire has only 500ohm/KMIt is usual to keep below 30% of maximum current carrying capacity.

Tim Mackey Posted May 15, 2008 Share Posted May 15, 2008 As a rough estimate only, assuming good quality silicon sheathing, and well soldered gold connectors etc, then I usually reckon for the 3 most common cable and connector sizes on about.....2 mm - 40A3.5mm -70A4mm - 90AThese are my estimates only and not based on published figures ( which seem very hard to find )Deans ultra connectors are good to 80A. Some sites suggest that these figures may be even higher, but I err on the cautious side,. Quote Link to comment Share on other sites More sharing options...
Brian Parker Posted May 16, 2008 Share Posted May 16, 2008 Just found a wire table.....for single wire, not multi-strand.In an enclosed environment (no heat loss?) A 19swg(1mm approx) wire max current should be only 1.2A In open environment the above wire will start to melt (fuse) at 81A (approx. subject to thermal conditions).Plenty of room to experiment then!
