mryan23 Posted November 9, 2011 Share Posted November 9, 2011 I've seen several places that say 18AWG spt-1 wire is ok for up to 7 amps, some say 2.5 some say as high as 10. Does anyone know what it is really rated for? Link to comment Share on other sites More sharing options...
thevikester Posted November 9, 2011 Share Posted November 9, 2011 Most that I have seen, as you described are rated at 10 amps, according to my reading, and the vendors that I buy it from Link to comment Share on other sites More sharing options...

Surfing4Dough Posted November 9, 2011 Share Posted November 9, 2011 Don't forget that length of wire should be considered since there will be some voltage drop.
