You're a goddamned retard, boy.

Yes, and YOU, and he ARE said fools. WHERE are the patent numbers that follow his patent claims? Where is the ISBN number of his "book"? It seems that he ALWAYS fails to respond when he is confronted with those particular queries. His lame ass is too goddamned old for ANY of it to still be classified, so don't hand me any of that baby bullshit either.

I should have worded it as: The NiMH batteries seem to have higher internal resistance than NiCD. Try that wire trick with NiCD's. 26 gauge wire can pass far more than an amp ( just gets kinda warm ) as I've experimented. It shows how conservative the NEC is with wire ratings.

Mine has a series light to tell you current is flowing. NO light, no charging current. . . I DO NOT FOLLOW MANY OF THESE NEWS GROUPS To answere me address mail to snipped-for-privacy@aol.com

a litle aa nihm can put out an amp for over an hour with a 1800 ma hour rating. . . I DO NOT FOLLOW MANY OF THESE NEWS GROUPS To answere me address mail to snipped-for-privacy@aol.com

Of course one can pass more than an amp through the wire, but if you did in say a transformer, it would likely overheat, and possibly short (nyleze).

What It shows is the maximum temperature rise which is considered acceptable, and safe for the material (Copper), and the coating, or sheath, and the placement of the conductor, in say a transformer, or raceway, for that size conductor. It is physical and scientific.

Is not the NEC based on fire prevention codes?

Fahrenheit 454 type stuff (actually much lower for the limits here).

Better technology than the old diode with a large resistor. They used to tell you the cells were designed for the 10 hour rate and could handle it but most didn't last 6 months if left in that kind of charger.

Yes, the NFPA is the 'owner' of the NEC. Most of their 'ampacity' tables are based on 60C and 90C temperature limits for the commonly used insulations. Other tables also exist. This is based on a certain ambient and the conductor material. Higher temperatures are provided for by a derating method.

It is real handy for bread boarding. You can clear the insulation with a soldering iron. . . I DO NOT FOLLOW MANY OF THESE NEWS GROUPS To answere me address mail to snipped-for-privacy@aol.com

Yeah I remember that stuff. when you terminated the end with a soldering iron the insulation would peel back around all the corners and leave you with bare conductors and a mess of plastic...LOL

I don't think it is in our current (pun intended) regulation charts though.
